October 7, nearly 50 people gathered in Mazingarbe to inaugurate the forest area, the seed orchard, and the greenway developed at the foot of slag heap 49.

This transformation was made possible by the circular economy of construction and public works land. An inauguration attended by local stakeholders The ribbon was cut by Sandra Guthleben, subprefect of Lens; Laurent Poissant, mayor of Mazingarbe; Michel Marchyllie, executive director of Espaces naturels r\u00e9gionaux (ENRx); and Julien Golaszewski of ECT.
