In June 2024, Ecomaison and Ecominéro launched their first joint call for projects to promote the reuse and recycling of inert building materials (PMCB) in the construction sector. We invite you to discover some of them while waiting for the opening of the first 2026 session.
With 120 applications received and 36 innovative projects selected, the high level of participation in the 2024 Ecomaison x Ecominéro call for projects illustrates the sector's commitment to the transition towards a high-performance circular economy.
These projects, led by project owners, prime contractors and various public and private works companies, give a second life to materials (wood, plastics, frameworks, etc.) and experiment with innovative approaches to reuse, throughout France.
