In the commune of Epône (78) ECT has worked with the bike club ORC Epône to create the first sports facility in the Île-de-France region for mountain biking and trials riding.

The club has more than 70 members. It does various forms of the sport (cross-country mountain biking, trials riding, cyclo-cross and adult sport touring). The ORC is designated as a bike school and competition club by the national governing body, the FFC or Fédération Française de Cyclisme.

4 questions for ORC Epône, for its president Franck Prestat and vice-president Philippe Gaudens.

Can you tell us about the various branches of mountain biking and trials riding?

Trials riding is done with a specific bike (with no saddle). It’s a spectacular sport, which requires flexibility, agility and balance to get round an obstacle course without putting a foot on the ground.

The mountain bike, which is much more common, is a bicycle for use on rough ground, off metalled roads.

ORC Club Epône - Vélo

What makes ECT’s involvement interesting for the ORC?

ECT’s involvement is what makes the project possible. Bringing inert soil to the site is financing the new developments. It means that the club will become the first in the Île-de-France region to have a terrain specifically for sport on two wheels – mountain biking and trials riding. It will also be the ideal location for hosting competitions.

How does the design of the new site work with bringing in soil from outside?

It’s bringing in inert soil that provides the opportunity to transform flat terrain into a very varied terrain almost like a stadium. It will make it possible for us to use the entire area of the terrain, and make the technical sections better spread out, more varied and more numerous. The height of the terrain lets us offer climbs and descents, and gives us more options in terms of the creation of technical sections.

What do you want the club to get from this new project?

The project aims to meet the needs of our two branches of cycle sport. Trials riding experts are always looking for new technical zones with obstacles, to add variety to their training, gain experience and improve their performance in competitions.

The total redevelopment of the site will let us completely rethink the zones so as to achieve better, more progressive technical levels. They will also delight our riders with new routes, whether using existing obstacles or new ones.

For mountain biking, we used to have to go elsewhere to find terrain with good training qualities.

Thanks to this project, we will have a wide range of technical sections for all levels right here on this site.

That means we’ll become more efficient in training our youngest members, as it will limit the travel distance to technical sections and at the same time increase safety (no roads to cross, etc.).

And aside from our youngest members, having a selection of benchmark technical sections means we’ll be able to assess riders as they progress through the various levels, and make up our groups accordingly – and prepare our competitors for the level of technical achievement that is expected.

Our adult mountain bikers will also be able to perfect their technique on a terrain that sets the standard.

A site to be rehabilitated 

At Roissy-en-Brie in the département of Seine-et-Marne (77), ECT is opening a new site on 27 July. The re-use of excavated soil will restore and conserve degraded farmland. Before starting, ECT cleaned up the site, removing waste that had been tipped there. The purpose of this development is to restore the land’s vitality. It will create an area of farmland, and areas devoted to biodiversity.

Conserving and improving an area of farmland

It’s about restoring agricultural holdings for their original purpose. This means restoring the productivity of the soil. The process of rehabilitation thus requires appropriate grading to create fertile soil, for a new agricultural area extending over 37 acres. When our involvement is over, the farmer will be able to resume operations on this land, and its agricultural role will have been secured for the future.

Recreating ecological continuity

The development recreates ‘ecological coherence’. It supports and is consistent with the living past and present of the commune. The goal is to ensure the future of natural habitats, with:

  • Conservation of existing natural environments (wetlands, small lakes, watercourses and neighbouring woods).
  • The reconstitution of a mosaic of environments, restoring ecological corridors and biodiversity in this district.

The project in figures

  • Launch date for the project: July 2020
  • Period of works: 2 years
  • Restoring 37 acres and returning it to agriculture
  • Creating ecological developments of grassland and wetland over 8 acres
  • Planting 11 acres of wooded slopes.

Read more about this restoration of farmland


On 27 July 2020, ECT opened a new site at Roissy-en-Brie in the département of Seine-et-Marne (77).

Bringing soil to this site will restore the productivity of an agricultural holding.

The works will last for 2 years.

For access to the Roissy-en-Brie site, prior approval is needed from the ECT’s Reservations department.

The site is equipped with scanners to read ECT’s electronic delivery tickets, as part of our contactless initiative for fully paperless working.

ECT is a member of UNEV (the national union of upcycling operators or Union Nationale des Exploitants de la Valorisation). In this video, UNEV’s president Albert Zamuner puts the spotlight on the sectors represented by UNEV.

He describes the work of its members, who have been very active during the health crisis to ensure that the construction & public works sector and local authorities could keep going.


[IN THE NEWS] “Covid-19: A good time to reflect on strategy”

Laurent Mogno, chairman of the ECT Group, spoke to Franck Boittiaux of

This discussion was an opportunity for the ECT chairman to give an initial financial assessment of lockdown and social distancing measures, and to explain the business’s approach to paperless and online communications with its customers in the construction & public works sector.

What are the consequences, especially in financial terms, of the health crisis and lockdown on the activities of your business, and the way you relate to your customers ?

“The consequences have been significant. We shut down all our sites from 17 and 18 March, while we set up new working procedures so as to safeguard the health of our and our customers’ workforces. We took about a week to re-open three sites, from 24 March, well spread across the Île-de-France in the 77, 91 and 95 départements. These sites seem well suited to ‘no contact’ working, and have adequate reception capacity, given that the ECT model consists of receiving soil excavated by construction and public works operators and offering solutions within a short travel distance.”

What steps did you have to take during lockdown ?

“Wherever possible, we shifted workers to teleworking, and set up strict procedures for the operational sites, with absolute ‘no contact’ working, in other words without using paper vouchers, without contact between members of our workforce or with customers, and with no shared equipment, whether that’s a computer keyboard or a bulldozer ! ”

How long do you think it will be before you can get back to a normal level of working, or even to get back to the 2019 level ?

“Probably not before September, and we will continue to monitor the situation thereafter because of the effects of Covid-19 and the municipal elections, so that we don’t experience a drop-off in 2021 arising from a lack of construction works, given that the various sectors involved are focussing very much on events unfolding today, and in particular on additional costs and the drop in productivity. Negotiations between the project supervisors and the construction and public works businesses on these subjects are complex and continually updated. As far as we are concerned, we have decided to absorb the costs arising from the new procedures.”

How has this period been for you? Has it given you an opportunity to think about possible reorganisations? Or changes to working methods ?

“It has been an opportunity to accelerate the process of going fully paperless, which was already at an advanced stage. We’re finalising our IT solution, which will be operational at the beginning of June and which will have an effect on productivity. It has also been a good time for reassessing the strategy of the business, especially in terms of the environment and biodiversity, because on 22 May the European Union published a roadmap which, in particular, promotes urban nature via the creation of plans for an ecological approach to urban and near-urban spaces in communes with more than 20,000 inhabitants, by the end of 2021. It’s a very interesting development for us, because its goal is the landscaping of spaces like those we make. Mankind needs nature in the city !”

Developing the first site for mountain bike and trials riding in the Île-de-France region

ECT opened the new site, in the Yvelines département and more specifically in the commune of Epône, on 15 June. The site upcycles inert soils from construction works in the west of the Île-de-France region, and it will include the first mountain bike and trials riding venue in the Île-de-France.

A quick introduction to the two sports :

  • ‘Trials riding’ is done with a special bike that makes it possible to tackle a series of different obstacles without setting foot on the ground.
  • Mountain biking, which is better known, consists of learning to handle a bicycle on rough ground from an early age.

A sports development in the Yvelines département

This stadium project has been “eco-designed” in conjunction with the club ‘Off Road Cycliste d’Epône’ (ORC Epône) and the Epône town council. The aim was to reconfigure the sports facility to provide the club with new technical zones and obstacles so as to give more variety to their training, increase their experience and enhance their performance in competitions.

Reshaping the site involves providing soil, making it possible to extend the mountain bike and trials riding area by nearly 5 acres. The development is fully financed by upcycling the soil.

The project will create a number of different zones. There will be technical zones with workout installations, ‘pump track’ and rock garden zones, and tracks with moguls and bends.

The project in figures

  • Project start date: June 2020
  • Duration of works: 4 months
  • 4.7 acres of training and competition terrain
  • 150 m² of rock garden, 300 m² of trials zone, and 2 pump track zones of 300 m²

New ECT site at Epône in the département of Yvelines (78)

ECT starts work at a new site at Epône, in the département of Yvelines.

The purpose of this site is to create the first mountain biking and trials riding centre in the Île-de-France region. It will be developed by upcycling soil excavated during construction works in the west of the Île-de-France region. The works are expected to last four months.

All access to the Epône site must be pre-booked with ECT’s Reservations department.

The site will also be equipped to scan e-tickets for soil deliveries, as part of our ‘Full Dématérialisation’ (Fully Paperless) initiative.

[IN THE NEWS] International journal “Ecological Engineering”

The international journal “Ecological Engineering” has just published a very interesting article.

The article is entitled: “Tree growth and macrofauna colonization in technosols constructed from recycled urban wastes”. It is co-authored by Charlotte Pruvost and Thomas Lerch (at the Institut d’Ecologie et des Sciences de l’Environnement de Paris, Sorbonne University, CNRS, UPEC, Paris 7, INRA, IRD).

The subject of the article is how to use technosols to provide sustainable alternatives to the large-scale importation of topsoil, in view of the increasing need to ‘green’ the cities. It is a research topic already explored by Charlotte Pruvost in a CIFRE thesis supervised by Thomas Lerch and funded by ECT.

Opening of a new site in the département of Essonne; a future equestrian centre

Developing a riding centre by upcycling inert soil

On 8 June ECT began a new site in the commune of Chevannes, which is in the département of Essonne. The purpose of this site is to re-use inert soils from the construction sites of the south-west of the Île-de-France region to create a horse-riding centre.

This equestrian project has been “eco-designed” in conjunction with the equestrian committee of the Essonne and the council of Chevannes. The objective was to define in advance the areas to be developed for horses and riding, and to set out how the site should be managed for the environment and biodiversity.


The goal is to create a full-featured, eco-friendly equestrian centre

This sports centre will cater for all equestrian disciplines. Bringing in soil makes it possible to create terraces on several levels. The terraces will provide a place for dressage arenas, and their flanks will be used for cross-country. The development is fully financed by upcycling the soil.

ECT is taking the opportunity of reshaping the site to promote the development of biodiversity. The various zones form part of a landscaping development of green space and wooded slopes.

Aménagement du centre équestre - Chevannes (91)

A number of different zones are included in the project. There are to be a manège or horse schooling area, stables, a clubhouse, and a car park with 100 spaces.

The project in figures

  • Project start date: June 2020
  • Duration of works: 2 years
  • 27 acres of land reclaimed as an equestrian centre

New ECT site at Chevannes in the département of Essonne (91)

ECT today opened a new site, at Chevannes in the Essonne (91).

The purpose of the site is to create a centre for horse-riding by upcycling soil excavated in construction works in the south of the Île-de-France. The works are expected to last two years.

All access to the Chevannes site must be pre-booked with ECT’s Reservations department. The site will also be equipped to scan e-tickets for soil deliveries, as part of our ‘Full Dématérialisation’ (Fully Paperless) initiative.

For all information about the conditions for access to the site (location, types of soil accepted, opening times, truck types), click here


Traceability of soil, efficient unloading, compliance with COVID-19 hygiene rules

On 4 June, ECT launched its fully paperless system for soil delivery tickets. That means ECT is now paperless for the whole process of issuing, delivering and checking tickets. And from this week, 100% of ECT sites will be equipped to scan their QR codes. The site entry ticket is an important link in the chain of traceability for the soil and materials received on our sites.

This project for e-tickets began some months ago as part of the business’s environmental initiative, and the health crisis gave it added impetus. The implementation of ‘no contact’ facilitates collections from the sites of customers in the construction & public works sector. They also help with efficient traffic flow at the sites where we upcycle the soil.

This has a three-part objective for our customers :

  • Shorter times when a driver arrives.
  • Better traceability of materials.
  • Better compliance with social distancing and other protective measures.

The technology is integrated with the customer service provided by ECT

Designed with our tech partner CKdev, this responsible approach is fully integrated into the customer experience so as to optimise pre-booked access to our sites.

There are 4 key steps :

  • Creation by ECT of e-tickets when entry is booked.
  • The e-tickets are sent out by email
  • The e-tickets are completed by the customer, with the driver or haulier.
  • The QR code for each e-ticket is scanned on arrival at the ECT site.

The issue, transfer and approval of e-tickets can be viewed in real time in ECT’s online client area.

Fertile substrate created on-site in the Bois de Vincennes, Paris

A responsible solution for greening the city

The on-site production of a fertile substrate or growing medium is an environmentally-friendly solution, making it possible to extend “nature in the city”, a major environmental factor for the cities of tomorrow. This growing medium is a local and sustainable alternative to importing of topsoil, which is a natural resource that should be left intact.

For 10 days, ECT has been creating a fertile substrate on site. This growing medium, which is essential for restoring vegetation to the Esplanade Saint-Louis, is an application of ‘circular economics’; the fertile substrate comes from recycling inert soil together with composted plant/vegetable waste.

A recycling plant on a landmark site

The purpose of the works is to landscape the traffic junction next to the Château. The requirement was to produce a recycled growing medium to re-green the Esplanade to a particular contractual specification, because the grassed area will be for public use for open-air events.

On-site creation of a fertile ‘technosol’ is one of a line of experiments already carried out in conjunction with the City of Paris. These experiments have been carried out within the Bois de Vincennes, in the context of a call for proposals by Paris Région Lab.

« The concept of fertility is integral to ECT’s business. We use a high-grade material in the form of inert soils from the construction & public works sector, to recreate fertile soils and to offer communities and local authorities a base for planting that is environmentally friendly, recycled and locally produced. And without falling back on topsoil stripped from the land hundreds of miles away. » Laurent Mogno, président d’ECT. 

The fertile substrate for reconstructing soil, and its agro-ecological qualities

2,800 cubic metres of fertile substrate have already been produced in this way. The process for making this substrate can be modified to meet a particular contractual specification. A range of soils and aggregates can be used. These materials are levelled out on site, before being covered with a layer of vegetable compost. Once this “layer cake” has been created, the substrate is given a full-thickness blending to produce a consistent texture. The growing medium is now ready to be planted by a landscaping business.

The ‘circular economics’ of soil excavated for “Vert en Ville” or greening the city

This site represents another advance in the deployment of a ‘circular economy’ of excavated soil at the service of communities and local authorities. A circular economy involves maximum recycling with the minimum addition of raw materials, water and energy, as opposed to the extraction-manufacture-consumption-disposal model of linear economics. The re-use of inert soils represents a striking opportunity for the creation of natural, agricultural and leisure spaces. It’s an important issue, given that 63% of town-dwellers in France say they would like to see more green spaces created in their neighbourhood (study carried out for ECT by IFOP in February 2020).

The production of a fertile substrate that’s suitable for planting in an urban environment has been the subject of several years of R&D by ECT, culminating in 2019 with the creation of Urbafertil, a branded substrate with a composition that varies for each project but always meets the French standard NF U 44-551 (growing media).

ECT sponsors a garden at the International Garden Festival at Chaumont-sur-Loire

The Festival International des Jardins in the Domaine de Chaumont-sur-Loire opened its doors last Saturday. This opening took place in circumstances greatly impacted by the health crisis of COVID-19. That’s why ECT is particularly proud of having supported the creation of one of its gardens, “Jardiniers de l’Invisible” or gardeners of the invisible. 

In the words of its designers, who are students at the ENSP national landscaping school  at Versailles (the École Nationale Supérieure de Paysage), this garden puts a question to the visitor: “How can we restore lost links with our earth, the remarkable original model of living together, sharing and symbiosis?” ECT also co-funds a business chair, “Earth and Landscape”, at the ENSP.

For 6 months, this festival is the don’t-miss international garden venue. Visitors explore a world dedicated to creativity, imagination, poesy and nature, which has been acknowledged as such since 1992 by professionals and by garden lovers. Every year the festival welcomes landscape gardeners and designers from all over the world.

ECT supporting the re-start of the construction & public works sector

The re-opening of construction and public works sites is under way, with an increasing number of sites, including several Grand Paris Express (GPE) lines, now back at work.

After a break for several days to put in place the necessary changes to crews and procedures for the fight against COVID-19, ECT reopened several of its sites from 25 March, to deal with residual activity in the construction & public works sector, and then to work with the sector as it restarts.

At the end of April, five sites were receiving loads from our customers and we were ready to open others to keep pace with the increasing demand from the sector. One week later, at the beginning of May, 8 ECT sites are now open, and can be accessed under the system for optimising and pre-booking delivery slots that was put in place at the end of 2019.

These open sites provide complete coverage for the Île-de-France region.

Well done to all teams for making this happen !

Covid-19 – three ECT sites open

Three ECT sites are open to receive soil and materials from our customers. These are the sites at Chelles (77), Forges-les-Bains (91) and Cormeilles-en-Parisis (95). To achieve this, ECT has put in place appropriate procedures to cope with the health risks linked to Covid-19, to ensure for both our workforce and our customers the necessary conditions for restarting work at its sites.

Access to these three sites must be pre-booked via ECT’s sales and service department.

In the context of this re-opening, ECT remains vigilant in the face of the Covid-19 epidemic, which calls for the greatest care. Our goal is to protect all staff, both those of ECT and those of our customers. And to guarantee the most effective implementation of traceability for the soil that we re-use.

At a time when the functioning of the country has been impacted by the Covid-19 pandemic, we are conscious that the entire construction & public works sector is calling for sites to be re-opened, provided that safe working is possible on site and that there is somewhere to send the excavated soil.

To date, our three open sites provide geographic and quantitative cover for the slots that have been pre-booked by our customers. We are entirely at their disposal to assess and respond to their needs in the coming days and weeks.

[In The News] Le Moniteur – A new look at the management of excavated soil

Le Moniteur – March 2020 – Special issue: ‘Circular Economy’ initiatives

Excavated Soils: A new look at waste – an article by Laurent Miguet 

In the département of Seine-et-Marne, the re-use of 13 million cubic metres of material has turned ‘spoil’ into a wooded park. In 2014 the old gravel pit of Villeneuve-sous-Dammartin became an ECT site for depositing inert waste. From 2024, the site will host “The Eyes of the Sky”, a gigantic artwork by the architect Antoine Grumbach, created out of excavated soil. These two eyes, each 400 yards long and 170 yards wide, will be visible to travellers landing at the Roissy- Charles-de-Gaulle airport.

 “Our project is located near the Mesnil-Amelot railway station, terminus of the future Line 17 of the Grand Paris Express, and it has every advantage to make it a destination in its own right. It ticks all the boxes in our work of developing non-built environment”, says Laurent Mogno, chairman of ECT

“Soil is not part of the circular economy for its market value. We’re advocates for its re-use, both societal and symbolic”, explains Antoine Grumbach.

The French law on ‘circular economy’ provides for the balance that ECT advocates, by encouraging communities and local authorities to take up opportunities for land-use development projects, without losing the benefits of traceability arising from the legal status of excavated soil as ‘waste’.

“Greening the City”: a new urban challenge

A study carried out by IFOP for ECT on the expectations of town-dwellers relating to “vert en ville” or greening the city

With the municipal elections coming up, ECT, developer of sustainable projects using soil from construction and public works sites, unveils the results of a survey* carried out by IFOP on town-dwellers and “greening the city”. Involving more than 2000 urbanites, the study shows the strong attachment of town-dwellers to green spaces and to their benefits. Most French people who spend time in the green spaces are happy with them. However, the 18-35 generation of Millennials stands out. They have much greater expectations about the use of green spaces. With the approach of the municipal elections, this is a political issue because 72% of people in the survey said that the question of “greening the city” would play a major or decisive role in the polling booth.

« Townspeople have real expectations, in terms of the creation and development of green spaces, but also in terms of facilities and services. Urban farms, linear parks and green corridors, land art, sports installations, and so on. It is vital to tackle this fundamental issue for the well-being of residents », emphasizes Laurent Mogno, chairman of ECT.

IFOP’s analysis is that « the study shows that ‘Millennials’ have a generational aspiration towards there being more green spaces in cities, and more facilities for the things that interest them. A significant gap has opened up between them and the Baby-boomer generation, who are satisfied with green spaces and equipment in their current state. »

Overall satisfaction, but higher expectations on the part of the 18-35s

  • 74% of French town-dwellers are satisfied with the number of squares, parks, gardens and green spaces in their commune.
    The average amongst the 18-35s: 63%
  • 66% of those surveyed would go there more often if the number of such spaces increased.
    The average amongst the 18-35s: 73%
  • 60% of those surveyed would go more often to the green spaces in their town if there were more facilities (sports, games, relaxation spaces, etc)
    The average for the 18-35s: 75%
  • 59%  of those surveyed would go more often to the green spaces in their commune if there were more activities (gardening, sports courses, workshops, etc)
    The average for the 18-35s: 72%

Half of city-dwellers consider that there are enough :

  • Children’s play areas (50%)
  • Parks and gardens (49%),
  • Outdoor sports installations (45%),
  • Woods and natural spaces for flora and fauna (45%)

But the 18-35s stand out and express frustration:

  • Only 43% are satisfied with the quantity of parkland, gardens and green spaces in their communes – 6 points less than the national average
  • As regards sports in town, 37% are satisfied – 8 points less than the national average
  • And for areas dedicated to the conservation of flora and fauna, 39% are satisfied – 6 points below the national average

A close link, and recognition of the benefits of “greening the city”

All the French believe in the benefits of green spaces :

  • On the personal level: 92% believe that green spaces in the city improve morale.
  • As a social bonding factor: 82% think that “greening the city” contributes to reinforcing the social bonds between residents.
  • As a direct contribution towards the environment: 92% see them as islands of freshness in city centres. 91% see them as a factor in improving air quality. And 89% see an opportunity to create places for biodiversity.


Places at the heart of their everyday life for 7 town-dwellers out of 10

Green spaces thus constitute part of everyday life for town-dwellers. 7 out of 10 say they spend time in a park, square or public garden in their commune at least once a month; at least once a week for 34%, and every day for 4%. Only 29% of city dwellers say that they never spend time in green spaces.

This close and very strong link between the French and green spaces can be explained in terms of the geographical distribution of green spaces:

  • 36% of town-dwellers said they live less than 5 minutes on foot from a square, park or public garden,
  • 34% between 5 & 10 minutes away on foot, 19% between 11 and 20 minutes away
  • and 11% more than 20 minutes away.

As regards leisure activities:

  • 88% of town-dwellers who were asked said that they go for walks there
  • 71% of people who were asked said that they did relaxation and leisure activities there (picnics, reading, sunbathing, etc).
  • 64% of respondents go more for games and family activities
  • 63% do a sports activity in the open air.
  • 46% of town-dwellers (which is almost one person in two) who were asked would do more gardening if the infrastructure was there to make this possible.

Methodology of the study

The survey was carried out with a sample of 2,005 town-dwellers who were representative of the adult population of urban communes in mainland France.

To ensure that the overall sample was representative, quotas were used for:

  • Socio-demographic criteria: The gender of the individual; the age of the individual;
  • Socio-occupational criteria: The individual’s profession;
  • Geographic criteria: The region and size of the urban unit of the commune of residence.

These quotas were defined using INSEE data for the population aged 18 or above and living in mainland France (Enquête Emploi 2015).

The interviews were carried out with self-administered online questionnaires between 31 January and 3 February 2020.

A job with a story: site reception

Whatever their area of expertise or trade and whichever site they work on, the staff of the operations department of ECT contribute every day to “making landscape”.
Despite the rigours of the weather, they have to stay optimistic and persevering. And work together, in a team, to shape these earth hills and these projects.

Through portraits of these men and women, we let you discover what they do and what is important to them. In this edition, we put the spotlight on site reception personnel.

Site reception: A key stage in traceability?

Every year, ECT receives nearly 15 million tons of soil. The traceability of this soil is a major factor in the management and re-use of excavated soil. On every site, the soil is checked at the reception point.

The site reception officer carries out the first checks in situ:

  • enregistrement des documents contenant des informations sur l’origine du chantierrecording of the documents that contain the information about the place of origin
  • checking the admission documents
  • checking the load on the truck
  • communicating and checking safety instructions, traffic rules and tipping rules

Site reception officer: a line of work for women too.

On several sites, the reception points are staffed by women. This role calls for working fast, getting it right, and being firm.

You have to know how to manage the flow of trucks entering the site and keep waiting time to a minimum. And sometimes you need determination to turn away a load because of a problem with traceability or with the quality of the soil.

“Here, at this point, you need to have character, be disciplined and give your instructions with a smile”

“My role is to control the loading of the trucks, do data entry and manage safety.”

3 questions for Jonathan Bryden, director of the “New Products” department

3 questions for Jonathan Bryden, who joined ECT in September 2019. He is director of the “New Products, New Services” department. That puts him at the heart of the business’s innovative approaches and the monetising of ECT’s fertile substrate, Urbafertil.


What were the origins of Urbafertil?

The origins of Urbafertil go back a long way. The interactions between our land-use developments using inert soils and the fertilisation of the soil emerged very rapidly as one of the key issues in our work as developers.

From 2002, ECT was involved when some parts of the Park de la Corneuve were ‘greened’ with a mix of excavated soils and compost. The experiment was observed and funded by the Council of the département of Seine-Saint-Denis.

Building on that, from 2002 to 2013, ECT was associated with a scientific committee on fertile substrates which included representatives from ADEME, from the Conservatoire Botanique National, from INRA, from the UMR Biogéochimie et Ecologie des Milieux Continentaux, from the Université Paris Est and from the Bioemco laboratory.

The work of this scientific committee resulted in a 4-year phase of experimentation (2013 -2017). This experimentation took place on the ECT site at Villeneuve-sous-Dammartin (in Seine-et-Marne, 77).

It was observed scientifically by Charlotte Pruvost, a PhD student at the Institut d’Ecologie et des Sciences de l’Environnement in Paris. The title of her thesis was:

The potential for biodiversity in the construction of technosols from urban waste“.

This thesis was presented in December 2018 before a jury consisting of members of the Muséum National d’Histoire Naturelle, senior lecturers from the University of Lorraine and professors from the universities of Rouen and Dijon.

In 2019, ECT set up a Research & Development department. Based on prior experimentation, one of the tasks of this department is the production and monetisation of a fertile substrate or growing medium. Production work is done in close co-operation with Biodepe, a subsidiary of ECT that specialises in organic waste and soil fertility. From December 2019, ECT was able to take this to a new level, by offering communities and local authorities its own brand of fertile substrate: Urbafertil

Why use Urbafertil as a growing medium?

Today, when a local authority is looking at projects to restore vegetation, the common practice is to import topsoil. These soils are stripped from fields located outside the towns and transported to the site where they’ll be used. However, there are solutions that are local, recycled and highly effective. That’s why it is important to think outside the box and favour bringing in local products.

It’s important to note that the traceability of topsoil is not always optimal. Urbafertil is partly made from inert soil from construction and public works sites located near the site to be ‘greened’. These inert soils have the advantage of compulsory traceability for excavated soils..

Urbafertil is produced purely by recycling, and comes from the combined re-use of inert soil and compost made from vegetable waste. Urbafertil is a successful example of ‘circular economy’, with very competitive prices compared to the price of topsoil.

A number of projects to create growing media using Urbafertil are under way in the Paris region.

What are the new products and new services that you are working on?

The whole ethos of ECT’s R&D department and the management of “new products and services” is to encourage a forward-looking and innovative approach. ECT has committed itself to this approach of innovation by creating partnerships with innovative businesses. The goal is to offer to communities and local authorities a range of new products and services to meet their need for estate management and development.

This has already resulted in the launch of the Urbafertil substrate, and also membership of Cycle Terre. This organisation aims to create a pathway for re-use of inert soil from the construction & public works sector, constructing new spaces from raw earth.

We are very aware of the environmental and societal impacts of the developments we carry out. And we are conscious of their potential, and their ability to have an extremely positive impact in the medium and long term. ECT is currently working on tools to make it possible to highlight the effectiveness of our solutions from the environmental perspective, and to demonstrate their advantages over other solutions.

The solar park at Annet-sur-Marne under construction

What’s happening at the Les Gabots site at Annet-sur-Marne?

The transformation goes on at ‘Les Gabots’ at Annet-sur-Marne, on the site planned as the location for a solar park. On a recent visit to the work site, ECT was impressed by the profound changes to the hills that will become one of the largest photovoltaic (PV) power plants in the Île-de-France region. Akuo is currently installing the solar panels. Activity is intense. Between now and summer 2020, more than 44,000 solar panels will be installed on the 45 acres of rolling landscape shaped by ECT.

Annet-sur-Marne, a renewable energy town

14 November last year was the day of the official fitting of the first solar panel for the PV power plant, in the presence of the mayor of Annet-sur-Marne, Christian Marchandeau, the vice-president of the Conseil Régional, Jean-Philippe Dugoin-Clément and of Eric Scotto, the chairman and founder of Akuo. All those present were delighted by the launch of this site for green, renewable energy.

With peak production of 17 MW from the solar park, the town of Annet will become a net producer of renewable energy

A partnership between the LPO and ECT to support the Little Owl

Respect for the environment and the conservation of biodiversity are at the heart of ECT’s values. That’s why we pay particular attention to the impacts of what we do. Even better, we are keen to work proactively in favour of biodiversity. This is underlined by the charter of commitment we’ve signed with the Humanité & Biodiversité organisation.

Now we need to turn this commitment to biodiversity into practical action. That’s why ECT is working with the LPO (the Ligue pour la Protection des Oiseaux, which is the French RSPB or Audubon Society) within a partnership agreement.

The LPO is well known for its work to protect species. The purpose of the programme put together for the little owl (Athene noctua) in the Île-de-France region is to re-establish ecological continuity between the Val d’Oise and the north of Seine-et-Marne. And by so doing, to conserve the various populations of this bird in this region.

LPO is working with ECT to advice us on three of ours sites, which are situated within the study area for the little owl: Villeneuve-sous-Dammartin (77), Vémars (95) and Louvres (95). ECT’s part is to encourage it to establish itself there, and that means creating corridors.

On the Villeneuve-sous-Dammartin site, developments are already expected for this year. In particular, in the orchard zone, with the placing of nest-boxes for the little owl.

A France Inter report on ECT’s centre for biological treatment

This week, the France Inter series “La Terre au Carré” is broadcasting a series of reports by the journalist Juliette Prouteau. This documentary mini-series is about the soil excavated from Grand Paris Express work sites.

The report of 14 January focuses on polluted excavated soil. That’s why the journalist visited our centre for biological treatment of soil polluted by hydrocarbons, located at La Courneuve (93).

In the report, Jérôme Malherbe, the site manager, and Laurent Mogno, chairman of ECT explain how the centre carries out biological treatment of these polluted soils.

It gives an overview of the work of the first French centre of this totally-enclosed type, in various stages :

  • The soil is unloaded into specific bays for particular sites.
  • The centre then sorts and analyses the soils to identify the type of pollution.
  • The process of treatment can then start.
  • The treatment process ceases when analyses show that the hydrocarbons have been substantially cleaned up

ECT presents its work to the local authorities of the Yvelines département

The local authority news publication “Magazine des Mairies et Intercommunalités des Yvelines” ran a special article about the UMY conference day in the 2019 edition. It was an opportunity for feedback from the various stakeholders and participants.

As part of the “Sustainable Development” workshop, ECT gave a presentation about its work as an environmentally aware developer of the non-built environment.

In this new interview, Laurent Mogno, chairman of ECT, talks again about the potential for re-use of inert soil, and ECT’s ability to offer to create, for communities and local authorities, sports and leisure spaces that are good for biodiversity.

Best wishes for 2020

In 2019, the men and women of ECT enhanced the lives of people living in the Île-de-France region.

Let’s work together to build the landscape of 2020. With more green spaces, sports grounds, places to walk, places for farming in town and in the fields … and happiness for all.

ECT wishes you an excellent 2020

ECT signs up to a charter to support biodiversity

ECT makes a commitment to biodiversity

Bernard Chevassus-au-Louis, chairman of the association “Humanité & Biodiversité”, and Laurent Mogno, chairman of ECT, formally signed a joint charter of commitment to biodiversity. This Charter is the result of a year of joint work with a shared objective – to work in partnership on the challenge of conserving the living world, participating in increasing knowledge, and affirmation by carrying out positive acts for biodiversity.

ECT and the “Humanité & Biodiversité” association: a meeting of minds that began in 2019

“Humanité & Biodiversité” is an association whose main purpose is to help everybody take into account the synergies and unbreakable links between mankind and biodiversity. The association works to conserve the diversity of the living world, and wants to see biodiversity considered in every sector of the economy. How? By systematically taking account of the interactions between the economic and social spheres and biodiversity.

That’s why ECT has joined this partnership with Humanité & Biodiversité, so as to incorporate biodiversity thinking into the way ECT works.

Bernard Chevassus-au-Louis, chairman of Humanité & Biodiversité: “In our view, the conservation and re-establishment of biodiversity require us to take human activities into consideration, so that everything we do contributes towards conserving our natural capital. Humanity is part of biodiversity. Humanity depends on it, profits from it and is responsible for it. It seems to us to be essential to recreate natural spaces where people live, so they can taste, smell and appreciate biodiversity.”

A charter of commitment to biodiversity, co-drafted and co-signed

The goal of this partnership is to grow together, and for each to better understand the activities of the other. The teams of each organisation have worked together to produce this charter which reflects a shared vision and commitment.

The charter takes into account the special characteristics of ECT’s work as an operator of non-built developments. In this way, we intend to reinforce the ways we work in regions that have strong potential for biodiversity.

Laurent Mogno, chairman of ECT: “There aren’t many organisations like ECT that have the ability to create green, non-built developments with an environmental agenda. We are a manufacturer of landscapes on a grand scale. I believe that our approach to biodiversity on our projects must be proactive. This is the ambition and spirit of this charter. ECT definitely has the ability to make firm and lasting commitments to create, into the future, habitats that are re-worked, reconstituted, and conserved.”

The charter of commitment will be reflected, from 2020, in operational matters

The objective of this charter is to increase our expertise in carrying out our developments. Meeting this challenge means a commitment to three things:

  • Turning the potential for biodiversity of ECT sites into reality
  • Training our people in biodiversity issues
  • Participating in the development of knowledge on biodiversity

The charter is intended as a guide for the business. It is to be seen as a resource for putting in place a practical methodology. 2020 is going to be the year for providing the business with a map of practical and appropriate responses in support of biodiversity.

“Earth as a Material”, a new book by Antoine Grumbach

Antoine Grumbach is an architect and town planner. This book is a reflection on metropolitan (metropolitan France, that is) land art. It gets its impetus from his awareness of the sheer volume of soil excavated by the construction & public works sector in the Île-de-France region.

Antoine Grumbach has no doubts – soil is a marvellous material. He explains all in his book entitled: “La Terre comme matériau: les Belvédères du Grand Paris”.

In the book, the architect and town planner describes the project of “made hills”. A visible sign of a symbolic ‘circular economy’, they have sprung up at the edges of the Paris metropolitan area.

ECT shares this ambition with Antoine Grumbach; the ambition of turning an “astonishing, intelligent, poetic, bold, useful” project into reality – the belvederes or lookout hills of the metropolitan area.

The sketches in the book illustrate these discoveries and explorations. The book unveils a laboratory of the imagination. They are steps to celebrate the fragility of the limits of the metropolitan area, as symbolised by these belvederes.

[In The News] Annet-sur-Marne: The transformation of the ECT site into a solar park has begun

To mark the start of works on the 17 MW solar park at Annet-sur-Marne, the first panel was officially fitted on 14 November. 

In March 2019, ECT and Akuo joined forces to create a shared subsidiary called ACT-E. Its objective: To develop solar energy in the Île-de-France region. The first project has been taking shape since November.

14 November was the official ceremony for the fitting of the first photovoltaic panel at the future Les Gabots solar park, in the presence of the mayor of Annet-sur-Marne, Christian Marchandeau, and the vice-president of the Conseil Régional, Jean-Philippe Dugoin-Clément.

The 45-acre project includes the installation of 44,000 solar panels. That’s why the works will continue until the end of summer 2020.

Present at the opening ceremony, Hendrick Delaire, a journalist for Le Parisien, spoke to the various participants:

Eric Scotto, chairman and co-founder of Akuo Energy, said “this power plant will produce 17 megawatts. That’s enough to provide 3,700 homes with electricity, which represents about 10,000 people. That will make the Annet commune a net producer of energy”.

The output of the future panels will be enhanced thanks to the combination of the skills of the two companies. Laurent Mogno, chairman of ECT, explains: “ECT is reshaping some terrain to give the panels a better orientation and thus optimise the insolation or amount of sun they receive”.

It’s their first project, but they have no intention of letting the co-operation come to an end any time soon. Akuo and ECT “expect to develop more solar parks on sites that ECT has already created using inert waste.”

Laurent Mogno, chairman of the ECT Group, spoke to Catherine Bernard of Le Journal du Grand Paris..

Laurent Mogno re-examined the definition of “inert soil”, and the concept of “la valorisation des terres” or upcycling soil. He started with a reminder that re-using excavated soil provides an opportunity for development in the regions, and for biodiversity. It was the soil from ‘The Hole’ at the Halles de Paris that went to make the landforms in the park at La Courneuve. And this park is classified as a Natura 2000 site.

During this interview, Laurent Mogno explained how the ECT company deals with soil from works on Grand Paris Express sites, and in particular the soil from the tunnel-boring machines. And how 100% of the soil from the GPE that is entrusted to ECT becomes part of the creation of land-use developments – whatever regulatory framework resulted in authorisation to re-use these soils.

[Appointments] ECT restructures its strategic approach and reinforces its dialogue with communities and local authorities

ECT is focussing and accelerating its growth as a major player in green developments for leisure, sports and agriculture.

ECT is focussing and accelerating its growth as a major player in green developments for leisure, sports and agriculture.

With two new appointments, ECT aims to focus its growth and reinforce its dialogue with communities and local authorities.

As the leading operator in France of a ‘circular economy’ for the excavated soils of the construction & public works sector, ECT is keen to develop its position as the go-to organisation in non-built developments for leisure and urban agriculture.

With this business dynamic in mind, ECT’s management has been strengthened by two appointments:

Guillaume Pasquier has joined the business as Director of Development. He is thus in charge of working with local authorities to develop ideas for new projects. His role also includes dealing with the large regional competitions.

Jonathan Bryden has become Director of New Markets and Services. His role is to identify new opportunities for growth, and to lead the Group’s move into international markets.

Their careers:

Guillaume Pasquier received an engineering degree from Mines Nancy (the École Nationale Supérieure des Mines de Nancy) in 2000, and a Masters from Sciences Po Paris (the Paris Institute of Political Studies) in 2004.

He began his career with Procter & Gamble. He then became parliamentary attaché to Christian Blanc. In 2007, he went to the USA where he worked as policy officer for a consulting company specialising in environmental issuesIn 2008, he was a ministerial adviser in the office of Christian Blanc, who was then Secretary of State for Development in the Paris region. He was involved in the launch of the Grand Paris project. From 2009, he directed the pilot team for the planned EPA Paris-Saclay (Etablissement Public Paris-Saclay). He became the EPA’s first deputy CEO in 2011. For 5 years, he piloted one of the flagship development projects of Grand Paris. In 2016, Guillaume Pasquier joined the La Française group to develop a “Grand Paris holding company”. The object of this company was to invest in real estate development projects near the Grand Paris Express stations.

Since October 2019 he has been ECT’s Director of Development.

Jonathan Bryden has an MBA from ESSEC, and an expert knowledge of banking acquired at HSBC in London and then at Citigroup in Paris, London and New York. He has worked in mergers & acquisitions, company flotations, raising capital on financial markets, restructuring debt and advising investment funds. Jonathan has also advised on the development of start-ups in the United States and in Europe. In 2014, he became the head of international corporate development / M&A at PMU. He has worked on the development of businesses in Belgium, Germany and Brazil.

Since October 2019, Jonathan has been ECT’s Director of New Markets and Services.

A new project opens at Morangis in the Essonne département

A municipal vegetable garden to bring more nature into town

The site for the new vegetable garden covers 5,390m². This area is for sustainable market gardening, aimed at school canteens in town. Excavated soils are a very good basis for a market garden. Degraded soils can be covered with a layer of inert soil and fertile topsoil, and the new landforms help with water management. The site will also have an educational role. The process of taking over this new environment opens the possibility of education about biodiversity, exchanges and sharing in the garden.

A new archery range to expand the sports programme

A new 10,000m² outdoor site has been set aside for archery for the ‘Compagnie d’Arc’ club of Morangis. Access to the site will be arranged for people with reduced mobility. This sport will be done in complete safety, thanks to the installation of a protective bund. The raised area will be wooded with fruit trees planted on a layer of fertile substrate. This substrate is a product of combining recycled inert soils with green compost.

Design and numbers

The project is taking shape on land belonging to the commune. It has been entirely “eco-designed” in conjunction with the Morangis town council. The objective was to set out upstream, with the local authority, the content of the developments, their uses for the benefit of the region, and the environmental management of the site. ECT planned the access route for bringing soil to the site in such a way as to reduce the impacts of the works, and to help them become part of the fabric of local life.

  • An area of 33,000m² including 10,000 m² of sports space and 5,390 m² of urban market garden
  • Duration of works: 4 months bringing in soil, and 2 months developing the agricultural and sports aspects

The international journal “Accattone” dedicated a dozen pages in its sixth issue to ECT and its model for upcycling excavated soil.

The author, architect Galaad Van Daele, came to visit us in June 2019. He describes, in this very aesthetic article, his perceptions of two ECT sites. First, his visit to the Arboretum Park at Moissy-Cramayel (77) which was shaped by ECT using inert soil from construction sites in the Île-de-France region. Then, his exploration of our centre for biological treatment of soil polluted with hydrocarbons, at La Courneuve (93), the first of its kind to be entirely enclosed.

“The Grand Paris Express and the Challenges of Managing Spoil”, an article by Clémence Barral of Le Figaro

What is the future of soil excavated from the Grand Paris Express? asks Clémence Barral

How is it to be managed in the long term? What can be done with this ‘spoil’ made up of soil excavated from railway stations and by the tunnel-boring machines?

The local authorities have some projects of their own, and others, such as “The Eyes of the Sky”, have been conceived by Antoine Grumbach and the ECT company.

Line Magne, the Mayor of Moissy-Cramayel, and Laurent Mogno, chairman of ECT, open a new urban park

On 22 June, Line Magne, the mayor of Moissy-Cramayel, Anne-Marie Démoulin, the deputy mayor responsible for sustainable development, Betty Chappe, the deputy mayor responsible for developing the eco-district of Chanteloup, and Laurent Mogno, chairman of ECT, inaugurated the Arboretum Park. This park is a new leisure space, open to the public in the eco-district of the Arboretum de Chanteloup.

New, green, sporty and educational, that’s the Arboretum Park.

The opening ceremony was an opportunity to explore this new park, a magnificent ‘green corridor’ or planted walk, on foot or by bicycle. It has nearly 2 miles of walking / cycling routes, a street workout zone and an arboretum. The sports associations of Moissy took an active part in the day. In particular there was the Kids Stride Out event by the Inisports school, and Moissy-Cramayel Athlétisme, Moissy Musculation, Rando Nature et Loisirs M-C, Cyclo Club Moissy-Cramayel and the UFOLEP of the Seine-et- Marne département were also represented.

“I’m delighted that this park has finally become a reality and I thank the ECT company for bringing this ambitious project to a successful conclusion, together with the municipality’s own departments. As with the town’s other neighbourhoods, our eco-district will now have its own jewel-box of greenery. It’s a new place that the people of Moissy will not take long to make their own, in their own way to suit their wishes: strolls, sport, picking from small fruit trees, discovering the flora and fauna … “ Line Magne, mayor of Moissy-Cramayel

The design and funding are part of a ‘circular economy’ of soil excavated from the sites of the construction & public works sector

As set up by the ECT company, the creation of the park was completely funded by bringing in inert soil from construction & public works sector sites in the south-east of the Paris region. This has also funded landscaping, educational and sports developments.

« For the last 18 months, ECT crews have been working to create and finalise the Arboretum Park, in tandem with teams from the town hall. ECT’s business is creating land-use developments that are useful to the community and local authorities by re-using excavated soil. The Arboretum Park is a very fine example. » Laurent Mogno, chairman of ECT

The orchard, the lake and the arboretum enhance the landscape and the walking area

The deliberately environmental nature of these spaces for biodiversity has an educational aspect. The educational side appears in the many interpretative panels to help people explore the various sites and trees in the park. With the fruit trees in the orchard and the remarkable trees in the arboretum, the park is home to a lot of trees. There are typical native species as in the nearby forest of Sénart such as the pedunculate oak, the alder and the yew; and exotics such as the Japanese pagoda tree and the cedar of Lebanon.

A park open to all: Families, sportspeople and people with disabilities

As requested by the Town Hall and local associations, the Arboretum Park is accessible to all, and proudly aims to get the “Tourisme et Handicap” label. That means providing facilities suitable for this section of the public. Half of the routes are accessible to all, and they make it possible to visit the whole park. The signage, and the access to signage, have been developed specifically with this in mind.

An eco-district enhanced by the Arboretum Park.

The eco-district of Chanteloup already contains new homes and an urban farm. There is a plan for the construction of more new homes. The Arboretum Park represents, as a public amenity for shared leisure and sports, a new vector in the residential aspect of Moissy-Cramayel.


“Soil excavated from the Grand Paris Express is just part of our annual volume”, an article from Cadre de Ville

Laurent Mogno, the chairman and CEO of ECT: “Soil excavated from the Grand Paris Express is just part of our annual volume”

Interview by Rémi Cambau, for Cadre de Ville, Friday 21 June 2019

[The main operator in soil recycling in the Île-de-France region announces that it processes between 12 and 15 million tons annually. “We are a bulk player”, says ECT’s CEO simply, before affirming: “In a period of just two and a half years, we find a new role for the equivalent of all the soil that the Grand Paris Express will produce in twelve years.”]

ECT’s project for a fertile substrate, winner of a call for proposals from Plaine Commune relating to the recycling of materials from the construction & public works sector


As part of its look at the urban metabolism, Plaine Commune is piloting a new call for proposals. It’s entitled “Let’s work together to build new avenues for the re-use of materials from the construction & public works sector“.

For ECT, the objective of producing a fertile substrate has two recycling components: Recycling inert soil from the sites of the construction & public works sector, and recycling composted green waste. This mixture makes it possible to create technosols rapidly.


Topsoil is a natural resource that needs to be conserved. It’s important to limit imports of topsoil into cities as far as possible. ECT’s fertile substrate represents a 100% eco-friendly alternative:

  • Produced near where it’s going to be used, it reduces the carbon footprint of both urban green space developments and restoring farmland;
  • The product of twin avenues of recycling, the fertile substrate is a successful illustration of the ‘circular economy’.


Developing nature in the city means limiting or even reversing the artificialisation of soils. This makes it possible to boost biodiversity and provide residents with spaces for relaxation and leisure.

Less expensive than topsoil, ECT’s fertile substrate makes it possible to develop more green spaces, adding to well-being in town.


When you create a technosol, you can vary the characteristics of the soil depending on its intended purpose: Vegetation, biodiversity, drainage and/or loadbearing capacity.

With a fertile substrate, it’s possible to modify the circulation or retention of water and minerals. It is also possible to achieve better stability and greater loadbearing capacity.


The leader in France in the re-use of inert soil, ECT has unrivalled expertise in the management and classification of soils. This expertise includes producing fertile substrates. ECT also has a subsidiary called BIODEPE, a business that specialises in organic waste and the fertilisation of soils. BIODEPE manages the local supply of compost made from green waste, and the production of a fertile mix.

Processing 15 million tons of excavated soil per year, ECT is able to meet all the supply needs of its customers. That’s why we can also provide a substantial outlet for the green waste pathway in the Île-de-France region.


ECT checks the materials that go to make up its fertile substrate. Standards for analysis and traceability apply to both the inert soil and the green waste – unlike topsoil, which has no guarantee of analysis or traceability.

  • The waste codes for inert soil: 17 05 04 / 20 02 02
  • The waste codes for green waste: 20 02 01


  • French standard NF U 44-551
  • ECT’s centre of production is at La Courneuve (93), with roll-out planned for other ECT sites
  • It can also be produced in situ where it will be used
  • Available in ‘big bags’ or in bulk
  • Competitive prices

1,000 cubic metres of excavated soil for an Earthworks workshop run by the ENSP

Simon Boudvin, an artist and a professor at the ENSP national landscaping school, has led the first EARTHWORKS workshop in partnership with ECT. The goal of the workshop? To create an artwork in 4 days using 1,000m3 of soil.

For this workshop, with thirty-odd students from the ENSP or École de Paysage de Versailles, ECT made available: A site, inert soil, a bulldozer, and its operator.

The challenges? There were several:

  • To examine the conceptual roots of Land Art
  • To understand a landscape that has been reconstructed with inert soil
  • To create an object on the scale of the wider landscape

The challenge was taken up successfully! A new landscape appeared!

Launch of the first phase in the rehabilitation of the domaine of the château of Grange-le-Roy (77)

SAFER IDF has officially launched the first phase of the work to rehabilitate the ‘domaine’ or estate of the château of Grange-le-Roy at Grisy-Suisnes (77). Laurent Mogno, chairman of ECT, attended to describe the phases by which inert soil will be brought to the site.

The objective of the project is to restore the domaine’s farmland with plantations of walnut trees and wood for heating, and to rehabilitate the property’s heritage and the landscaped park.

A second life for an abandoned site

Site owner SAFER IDF (Île-de- France) has acquired the 170-acre estate of Grange-le-Roy at Grisy-Suisnes in the département of Seine-et-Marne. The historical and architectural aspects are being looked after by a private investor and ECT is working on the nature and landscaping aspects.

There have been several previous failed attempts to rehabilitate the estate of Grange-le-Roy. That is why the site today shows all the signs of being derelict. The château and its outbuildings are very dilapidated, and rubbish and illegal dumping sully the ground and the natural surroundings.

Taking it back by applying a principle of ‘circular economy’: The re-use of inert soil

The provision of inert soil makes it possible to create a forestry enterprise of walnut trees and trees for fuelwood. This soil will also make it possible to restore the other natural and landscaping spaces of the estate.

How? Putting the domaine back in order in terms of forestry and landscaping is possible thanks to ECT’s upcycling of inert soil. This soil comes from construction and public works sites in the Île-de-France region, and this finances the various developments and plantations. The soil will itself be used to remodel the domaine and the park.

Renewing the landscape with a public park and productive wooded areas

At the end of the project, when it is opened to the public, walkers will be able to explore some remarkable new features:

  • There will be a foundation for contemporary and digital art in the château and the park
  • The 2.5 acre walking area will be enhanced by a sloping bank providing an open panorama
  • The forestry will consist of a 50-acre plantation of walnut trees and 7 acres of fuelwood.
  • A new meadow and open spaces will offer a haven of biodiversity

Respect for biodiversity

The project will include a number of measures to conserve ecological habitats. It’s a question of sustaining sensitive natural habitats and encouraging flora and fauna.

On the 24 acres of natural habitats there are important ecological issues, especially as regards the open spaces and the wetland zones on the site. Ecological site management will reinforce the conservation initiatives. The wetlands will be conserved over 10 acres and recreated over 1.5 acres with the installation of reed beds. ECT is restoring 7 small lakes.

There will be specific developments for protected species. With the creation and restoration of lakes, there will be bat-boxes and refuges for reptiles. ECT has relocated amphibians and a protected flower (a bladderwort, Utricularia australis).

Finally, ECT is arranging for there to be ecological follow-up of the site over a period of 30 years.

The project in numbers

  • 30 years of dereliction
  • 30 years of ecological follow-up
  • 2019 = date when inert soil starts to arrive
  • 5 years = duration of the development works
  • 4,400 walnut trees planted on 50 acres
  • 6,240m² of wetland

BAP! : The “Earth Moving” (“Terres en Mouvement”) exhibition at the national landscaping school

Earth Moving: A look at the made-ground landscapes of the Île-de-France region

The exhibition takes place at La Figuerie (a historic amphitheatre) in the Potager du Roi at ENSP Versailles.

It is open from 4 June to 23 June as part of BAP! (the Biennale d’Architecture et de Paysage) at Versailles.

Civil engineering works in the cities are generating a considerable and increasing amount of inert soil. Consisting of both topsoil and subsoil, this is being deposited and re-used, making new landscapes.

In the context of the partnership that the ENSP has established with the ECT Group, the exhibition goes behind the scenes in the construction of landscapes, to take a fresh look at these sites made from the products of earthmoving; constructed landscapes, totally man-made, their movement and arrangement orchestrated by the landscape architect.

The exhibition also looks at the uses and the environmental and landscape qualities that meet and find expression there. Contemporary sites in the Île-de-France region provide a context for analysis. They find their echo in the Potager du Roi which has itself been the subject throughout history of successive earthmoving projects.

This exhibition also provides an opportunity to present the work of the photographer Anne-Marie Filaire, who was given an assignment by ECT.

Curators of the exhibition:
Marie-Laure Garnier, DPLG (the acronym indicates a Versailles-trained landscape architect)
Romain Bocquet, also a DPLG landscape architect, and a gardener

“We must promote the re-use of inert soil excavated from construction sites”: An article in News Tank: Cities

Interview with Laurent Mogno of ECT: “We must promote the re-use of inert soil excavated from construction sites”.  AUA – Paris – friday 17 May 2019 – interview number 146743 [“We must promote the re-use of inert soil excavated from construction sites: An article in News Tank: Cities. Upcycling this material from construction sites is a socially and environmentally useful activity. It’s not recycling. The objectives of re-using soil vary depending on the sites and the local challenges or issues in the region. In terms of landscape developments, there is immense scope. Our goal is to develop a circular economy of excavated soil to create useful developments that are part of a local dynamic”, said Laurent Mogno, chairman of the ECT group, on 07/05/2019. The ECT company processes between 12 and 15 million tons of excavated material every year (Parisian made-ground, clay, marl, sand and silt, rubble, ceramics, brick, rock, concrete, etc). 85% are inert soils, and the remaining 15% are made up of sulfate soils (spoil from gypsum quarries) and soil polluted with hydrocarbons that is processed at the ECT centre for biological treatment of soil at La Courneuve (Seine-Saint-Denis). According to the Société du Grand Paris, which is in charge of the Grand Paris Express (GPE) construction sites, the soil from the 15 tunnel-boring machines that are operating represents half the soil extraction. “ECT’s part of the market for managing and re-using soil from construction sites is in the order of 50%”, says Laurent Mogno. “The Île-de-France is the most dynamic region in France, where the most soil is being excavated”. The GPE construction sites produced 5 million tons of excavated spoil in 2017 and 2018, with a prospect of 43 million tons by 2030 (consisting partly of soil extracted by the tunnel-boring machines).] Read the complete article

“What’s to be done with the soil excavated from construction sites?”, an article by Sibylle Vincendon in Libération

Artificial hills on the ECT site at Moissy-Cramayel

A park created entirely with re-used soil will soon be officially opened by the mayor of Moissy-Cramayel in the département of Seine-et-Marne.

What’s to be done with soil excavated from construction sites?

A few weeks from now, the Mayor of Moissy-Cramayel (Seine-et-Marne) will officially open a park created entirely thanks to re-used soil. In twenty years or more, as the deposits are exhausted, the galleries of gypsum mines operated in the Île-de-France region by Placo will be backfilled with the same soil. Using the spoil that all the construction sites are excavating to fill other sites seems to make sense. It’s not the rule. The days are long gone when the civil engineers of Haussmann’s Paris “had a culture of excavate-and-backfill”, in the words of the architect Antoine Grumbach. The soil from the excavation of the Paris Métro was used to make the parks. Leader in the collection and processing of these soils, ECT does this kind of recycling when it’s possible. The least visible but most remarkable technique is that of using soil to backfill the galleries of gypsum mines when they’ve been emptied. The Île-de-France has a very good basin of these deposits, from which Placo, a division of Saint-Gobain, extracts the gypsum plaster used to make the famous drywall panels for the construction industry. Since 2000, the quarry companies have been required to backfill where they have excavated, to avoid the collapse of the galleries.] Read the entire article

“Near Roissy, giant eyes will be visible from the sky”, an article by Marion Kindermans in Les Echos

[ECT, a company that recycles excavated soil, will work with architect and town planner Antoine Grumbach to create a work of land art on 320 acres at Villeneuve-sous-Dammartin.

By Marion Kindermans

Spoil from construction sites turns into a work of art. Hills of soil from construction works in the Île-de-France region, accumulated over some years on the soil recycling site of Villeneuve-sous-Dammartin in the département of Seine-et-Marne, will soon be transformed into a green sculpture. On 320 acres and 100 feet high, this is the biggest such site in France.

Two giant eyes, 400 yards long, crowned with the logo of the 2024 Olympic Games, will be visible to nearly 70 million air travellers. This immense site is right in line with the runways of the Roissy-Charles de Gaulle airport, and less than a mile from the future railway station of the Grand Paris Express railway (Line 17) at Mesnil-Amelot.

It’s an exceptional geographic location, which prompted the Île-de-France company ECT, site owners and specialists in re-using excavated soil, and Antoine Grumbach, architect and town planner, to think of this slightly mad land art project. The Prefect of the département of Seine-et-Marne, Béatrice Abollivier, gave official approval to the project at the end of January.]

“Moving shovels, moving earth”, an article by Sybille Vincendon in Libération

Moving shovels and soil

By Sibylle Vincendon — 12 April 2019 at 11:24

[Every week, we run a story of towns, of villages and urban issues. Today we look at the destiny of the tons of soil that are being shifted for construction works. We’re talking big bulk.

So there’s this story of the guy who’s digging a hole. Another man arrives and says “Where are you going to put the soil?” And the first guy replies, “In another hole.” On all construction and public works sites, digging the hole is the first thing you do. But as you can’t dig a second one to pour the earth into, having tons of minerals to manage is no small affair.
When you look at spoil, you go behind the scenes in the world of urban construction; you’re now standing in the kitchen that you never hear about. “As soon as anybody gets building consent, there’s going to be excavated soil”, explains Laurent Mogno, chairman of ECT, which is a leading company in the business of collecting, processing and using soil from construction sites. “Construction companies pay us to take it away”. It’s the law. And then it’s up to the person who takes the soil to find something to do with it.]

Laurent Mogno at the microphone: He talks to Radio-Immo about ECT and inert soil

Questioned by Radio Immo at the AMIF conference, Laurent Mogno, chairman of ECT, explained the great potential for re-using inert soil from excavations. He revealed his strategies for identifying sites to develop, and he outlined the way soil can be upcycled; a method being put into operation across the region.

To listen to the interview with Laurent Mogno, click here

Using inert soil from excavations to rehabilitate and re-green sites is a very powerful financial tool for local authorities.

AMIF is the association of mayors of the Île-de-France region, and ECT has been attending AMIF’s Salon or conference for several years now.

ECT is a member of AMIF’s partners group. ECT’s business is essentially located within Île-de-France, because construction sites within this region are very active in both the building and infrastructure sectors. It’s one of the consequences of a very dynamic economy.

Along with Akuo Energy, ECT promotes solar power in the Île-de-France region

With ACT-E, their co-owned subsidiary, ECT and  Akuo Energy, an independent producer of renewable energy, are keen to duplicate the project at Annet-sur-Marne (77).

At Annet, they’re creating a solar power plant with 17 MW of panels. These will supply enough power for 3,700 homes (excluding heating).

The slope of the terrain, and shaping by ECT for optimum insolation (exposure to sunshine), combine to maximise the plant’s output. There is also the question of creating the best landscaping solution.

« UWe have identified a dozen sites that would be suitable for installations of 10 to 20 MW”, says the chairman of ECT, Laurent Mogno.

The shared objective of the two businesses is to produce about 100 MW of solar power in the region.

“The electricity produced can be sold to EDF and injected into the grid. That’s what will be done for the plant at Annet, which was the winner of a CRE public tender process”, says Eric Scotto. Eric Scotto is the chairman and co-founder of Akuo Energy ;

“Electricity can also be sold direct to businesses within a PPA (Power Purchase Agreement). Or used to produce hydrogen as a “Last Mile” solution.

“When excavated soil from Greater Paris helps to develop a region”, an article by Giuletta Gamberini in La Tribune

[The ECT company re-uses these soils to transform impoverished spaces in urban parks and farmland

27 March 2019, an article by Giuletta Gamberini in La Tribune

The enormous volumes are one of the main environmental issues for Greater Paris. How to upcycle the tens of millions of tons of excavated soil that will be generated by these works? 40 million tons will come from the Grand Paris Express alone. For the ECT group, operating in the Île-de-France region, this challenge is above all an opportunity. ECT has been active in this area since the 1970s, and it has developed a solution which goes beyond that traditionally offered by earthmoving companies, which consists of simply re-using these soils for highway embankments. Instead, ECT uses them for land-use developments. “We make parks out of them, but also fields or woods, where there are impoverished spaces – brownfield sites, sports grounds, rubbish dumps, abandoned quarries and so on”, explains the chairman of the business, Laurent Mogno.

The financial model used by ECT, which has already completed dozens of developments, is based on the status of ‘waste’ which legislation today applies to all this excavated soil, including the 80% of it which is ‘inert’ rather than polluted; in other words, which is not liable to deteriorate or to react in contact with other materials. The business’s income comes entirely from the price paid by businesses in the construction & public works sector to get rid of waste in a way that complies with the regulations.
ECT separates out and treats any polluted soils, and provides the certificates required for traceability of waste.

On its 15 sites in the Île-de-France region, ECT has the capacity to receive about 15 million tons of inert soil per year. And on some of them, like the one at Villeneuve-sous­-Dammartin, vast dikes have been created to receive tons of soil from tunnel-boring machines, which make up half the excavated soil from the Grand Paris Express, and which have particular physical characteristics that require suitable sites.]

Creation of a subsidiary by Akuo Energy and ECT to produce solar energy in the Île-de-France region

The goal: To produce 100 MW of solar energy

Akuo Energy is the main independent producer of decentralised renewable energy. ECT develops sites by re-using soil from sites operated by the construction & public works sector. Akuo Energy and ECT have announced the creation of ACT-E, a jointly-owned subsidiary. The objective is to increase the production of photovoltaic energy in the Île-de-France region, with the goal of achieving, on the sites developed by ACT-E, a total peak output of about 100 MW.

A question of optimisation and proximity

ACT-E is working on a regional approach of proximity – offering green electricity, produced locally, to the residents of the Île-de-France. This partnership between the two companies aims to optimise the performance of photovoltaic plants by first reshaping the site on which they are installed. The provision of soil by ECT plays a key role in reshaping the land to give the photovoltaic panels better ‘insolation’ or exposure to sunshine. This type of development also makes for better landscaping of the solar park.

The first operation – at Annet-sur-Marne

The first operation by ACT-E is already at the financing stage and will soon be under construction. It’s a solar park with a peak output of 17 MW, situated at Annet-sur-Marne (77) The Annet-sur-Marne project in figures:
  • Type: Solar park with fixed structures
  • Total area: 113 acres
  • Photovoltaic surface : 45 acres
  • Peak output: 17 MW
  • Production: 18,500 MWh/year
Laurent Mogno, chairman of ECT is delighted. “We’re very happy with this partnership. It exemplifies the principle of ‘circular economy’ which is at the heart of what ECT does. Essentially, ACT-E will produce photovoltaic electricity in a way that is perfect for the needs of residents of the Île-de-France region. The electricity will be produced on sites developed with soil from the construction of the Grand Paris Express. We can also celebrate making an energy contribution in future to the running of the metro.” Eric Scotto, chairman and co-founder of Akuo Energy, finishes up: “This partnership takes on a new form today with this subsidiary shared by ECT and Akuo. It will give a second life to sites. This renewable energy project demonstrates the strength of our partnership, at the service of the Île-de-France region and its dynamic economy.”

First conference on the re-use of inert soil by ECT and the EIVP

Soil is an amazing resource!

The EIVP (the City of Paris School for Engineers / École des Ingénieurs de la Ville de Paris) and ECT are organising, on 9 and 10 April 2019, a conference on the theme “La Terre dans tous ses États” or “Soil in all its States”. Presentations by Henri Bava and Antoine Grumbach, both winners of the town planning award ‘le Grand Prix de l’Urbanisme’, will conclude these two days of exploring soil engineering.

This conference is part of the EIVP / ECT chair, “Upcycling Inert Soil”.

  • Seminars and round-tables: Researchers, developers, elected representatives, experts
  • Site visit: To the ECT site for upcycling excavated soil at Villeneuve-sous-Dammartin (77)

Every year in the Paris region, the construction & public works sector excavate more than 10 million cubic metres of inert soil. That’s the equivalent of four Great Pyramids of Giza, and a quantity that is a barometer of the sheer volume of public works currently happening in the Paris metropolitan area.

The conference “Soil in all its States” proposes to reveal the thousand and one ways in which inert soil can be upcycled. It’s a golden opportunity to shine a light on the principles of ‘circular economy’ and ecological mitigation that are at the heart of these often unsung activities.

The speakers will explore numerous solutions:

  • Remediation of polluted zones
  • Creating planted parkland
  • Restoring farmland
  • Transforming soil into a construction material or a fertile substrate
  • Creating works of art

The conference is at the EIVP, 80 rue Rébeval, on 9 and 10 April 2019 from 09:00 to 17:00

A virtuous circle: The re-use of inert soil, a report by France Télévision

A report by France TV on “The Eyes of The Sky” was an opportunity for Laurent Mogno, chairman of ECT, to illustrate the virtuous circle of the re-use of inert soils. These soils are making it possible to create new cultural and leisure sites in the Île-de-France region . “The Eyes of the Sky” is a monumental work of Land Art that Antoine Grumbach is creating on the ECT site at Villeneuve-sous-Dammartin

Antoine Grumbach’s project: Two immense eyes, each 400 yards long. He is creating this work in the commune of Villeneuve-sous-Dammartin (77), a few miles from Roissy-Charles de Gaulle airport. Passengers taking off or landing will be able to look at “The Eyes of the Sky”, which will look back.

“3 rows of trees outline the eyes, with nearly 1,200 trees in all. Add to that 12,000 square metres of planted mound around them. At the centre of one eye will be a hedge maze the public can walk around”. The place will also host exhibitions, sports competitions, “and even a skating rink in winter”, says Antoine Grumbach.

The end result is still a little hard to visualise, because today it’s an immense site with 700 trucks arriving every day to dump their tons of earth from a number of construction & public works sector sites in the Île-de-France, including underground railway construction for the famous Grand Paris Express.
