What are the conditions of access to ECT sites?

An invasive alien plant species is a plant that is introduced into a new environment where it is not native, and which proliferates aggressively, causing ecological, economic or social damage. These plants may have been deliberately introduced for horticulture, agriculture or other uses, or may have arrived accidentally via international trade, transport or other human activities.

Once established in their new habitat, invasive alien plant species often have a competitive advantage over native species. They can spread rapidly, crowd out native vegetation, disrupt natural ecosystems, reduce biodiversity, alter natural nutrient and water cycles, disrupt ecosystem services and even threaten endangered species.

Controlling invasive alien plant species is a major challenge for biodiversity conservation and ecosystem management in many parts of the world. Prevention, control and eradication measures are often necessary to limit their spread and minimize their harmful impact.

On Sunday September 24, 2023, the ECT site in Villeneuve-sous-Dammartin (77)  exceptionally opened its doors for an outdoor escape game. An opportunity for the public to discover the land art work, “L’Œil du Ciel”, designed by Antoine Grumbach and produced by ECT. Earthworks and planting of the second Eye are scheduled for 2025. The site will open its doors to the public at the end of the excavated soil reclamation operation in 2027. 

Every year, in the Paris region, an estimated 20 to 25  million tonnes of soil are excavated by the construction industry, leaving the excavation site.

Thanks to its experience and the services it offers to the construction industry, ECT is the leader in excavated soil management in the Paris region.

In line with the principles of the circular economy, ECT reuses nearly 15 million tonnes of excavated soil on its sites every year. These contributions of land make it possible to design and finance development projects that are concerted, sustainable and useful to the region. 

The artist Saype has taken up residence in Annet-sur-Marne (77), on a site rehabilitated by ECT, to create his new lad art work. This ephemeral, eco-responsible fresco entitled “Un jeu d’enfant?” was painted in 3 days using pigments derived from excavated soil. This fresco is no longer visible:  it has faded naturally with the weather and the regrowth of ground vegetation. A sign has been installed on the site to commemorate this emblematic achievement.

Invasive Alien Plant Species (IAS) are one of the five causes of biodiversity loss. As a company committed to the OFB, ECT has a triple objective:

• the reduction of their proliferation on its sites
• limiting their spread from customer sites
• the creation of a dedicated offer for the management of construction site soil impacted by EVEEs

ECT has created a booklet to help you identify, learn about, combat and eradicate these species. This guide provides recommendations for each invasive plant: 

• Japanese wild buckwheat
• The Butterfly Tree
• Giant Hogweed
• Galéga Officinal
• Ambrosia
• Himalayan Balsam
• The thorny apple
• The American Grape
• Herbs of the Pampa

 It is important for site managers to regularly monitor the presence of EVEEs and implement appropriate control measures to limit their spread and impact. Here are the 7 best practices: 

• INFORMING OUR CUSTOMERS
  and transporters of the risk of inputs into the soil and dissemination on our sites.
• MAPPING
  impacted areas to measure their evolution.
• EVALUATE
  the type of intervention to be carried out depending on the plants and their location on the site.
• WATCH
  regularly to identify the presence of invasive plants.
• DELIMIT
  to avoid them on foot or with construction equipment.
• COMMUNICATE
  on our practices and results, with internal and external feedback.
• LUTTER
  Neutralize invasive exotic plant species by carefully uprooting them or burying them at the bottom of a bin.
  Contain invasive exotic plant species by surrounding them with more competitive plants.
  Temporarily revegetate bare soil with ground cover seedlings to render it unattractive.

Invasive alien plant species (IAS) can have a detrimental effect on construction sites, causing delays, additional costs and safety risks. It is therefore important for construction companies to implement measures to manage and control invasive species in order to minimize their impact.

1. Alteration of the construction environment: EVEEs can colonize construction zones, hindering construction and development activities. Their rapid growth can disrupt soils, structures and foundations intended for construction.
2. Additional costs: The presence of EVEEs can lead to additional costs for construction projects, particularly in terms of the time and resources required to remove these plants, restore disturbed areas or reinforce protection measures.
3. Safety risks: Some EVEEs can pose a safety risk to workers on construction sites. For example, fast-growing invasive plants can make surfaces slippery, increasing the risk of falls and accidents.
4. Damage to equipment and infrastructure: EVEE roots can damage drainage systems, underground pipes, foundations and other infrastructure, leading to costly repairs and longer construction projects.
5. Risk of propagation: Construction sites can act as dispersal vectors for EVEE. Machines, vehicles and construction materials can transport seeds and plant parts from one site to another, encouraging the spread of these invasive species to new habitats.

This is a systematic assessment designed to identify, evaluate and map invasive species present on a construction site. It generally recommends special measures for the treatment and disposal of plants and soil. EVEEs are plant species that have been deliberately or accidentally introduced outside their natural range. Their dissemination is one of the
5 causes of biodiversity collapse.

Inert materials are defined in article R541-8 of the French Environment Code.

These are materials that undergo no significant physical, chemical or biological modification. Inert materials do not decompose, burn or produce other physical or chemical reactions. They are not biodegradable and do not deteriorate other materials with which they come into contact in a way likely to cause environmental pollution or harm human health (Council Directive 1999/31/EC of April 26, 1999 – OJEC of July 16, 1999).

It is forbidden to dilute or mix waste for the sole purpose of meeting acceptance criteria (Order of October 28, 2010).

Inert excavated soil belongs to the category of inert materials.

A regulatory procedure: a validated DAP for each excavation site

For each project, our customers must submit a Request for Prior Acceptance (RPA) to ECT’s Quality department. This is mandatory prior to evacuation on an ECT site.

The DAP states:

• Geographical origin: site location;
• Producer’s contact details ;
• Carrier details ;
• Type and quantity of backfill.
• The information is then compared with the data contained in the database of potentially contaminated sites in the Ile de France region (BASOL).

Contact details and PAD templates 

• Requests for prior acceptance (RPA) must be sent at least 48 hours before the first deliveries,
• to the following email address
