Project presentation
In partnership with the Commune of Mazingarbe, this project aims to redevelop a derelict site at the foot of slag heap 49, by combining the installation of a seed orchard, the creation of an urban forest and the creation of a soft pedestrian walkway. The project also includes agricultural reprofiling for recultivation. The circular economy of soil from local building sites helps to self-finance this natural, recreational, ecological and educational area.

Project life
Mazingarbe, a study site for the ecological rehabilitation of mining sites
At the foot of slag heap 49, the ECT site at Mazingarbe is home to study plots for the European REECOL project, piloted in France by Ineris. This program aims to develop sustainable solutions for restoring degraded soils in mining regions.
The circular economy of building land at the heart of the transformation
November 2024 – Since the summer of 2024, excavated soil from our local partners’ construction sites has been transforming the landscape at the foot of slag heap 49 in Mazingarbe. Coming from a 22 km radius, the soil is part of a circular economy initiative to create an urban forest, a seed orchard and an agricultural area, while combating the Giant Hogweed. The traceability of inert soils is at the heart of the project: each input is controlled from source to final placement. A project that combines land reclamation and landscape rehabilitation, in partnership with local players and ENRx.
Rehabilitating the mining landscape through an ecological renaissance
Coal mining has left its mark on our landscape with the majestic slag heaps. These include terril 49, which has been transferred to the Conservatoire d’Espaces Naturels des Hauts-de-France for land protection. At the foot of the slag heap, the abandoned land is overgrown with various types of waste and colonized by invasive exotic flora, such as the dreaded Giant Hogweed.
The reuse of inert soil from local construction sites is an opportunity to rehabilitate this derelict land and transform the site. The transformation of the site is self-financed by the circular economy of inert soil, and will provide a natural space for relaxation.
This project has been designed with a multidimensional approach: ecological, landscape, sensory, well-being and educational.
4 project challenges :
- Creating an urban forest
- Building a seed orchard
- Maintaining agricultural land
- Opening the site to the public
