About

Nous recyclons les matériaux alternatifs issus de l'industrie comme les cendres de chaufferie, les sables de fonderie, les Scraps & les crasses de fonderie, etc… à destination de l'activité agricole, industrielles ou des travaux publics.

La mise en place de cette filière permet à la fois de donner une autre utilité à des déchets mis en enfouissement et cela permet aussi d'économiser des graves dites naturelles de carrières comme matériaux utilisés en TP. Le 3e impact induit du 2nd et le fait d'économiser sur les ressources mises en œuvre pour l'extraction. Cela permet de créer de l'emploi sur nos territoires.

Nous recyclons plus de 30 00 Tonnes/an, tonnage qui augmente de 50%/an depuis Trois ans.

Le bénéfice est donc à la fois environnemental, économique, social et sociétal.-------------------------------------We recycle alternative industrial materials such as boiler ash, foundry sand, scraps and slag, among others, for reuse in agriculture, industry, and public works.

This recycling stream gives a second life to materials that would otherwise be landfilled, while also preserving natural aggregates typically extracted from quarries for construction purposes.
By reducing the need for extraction, this approach also lowers environmental pressure on natural resources.
At the same time, it supports the creation of local jobs and strengthens regional economies.

We currently recycle over 30,000 tonnes per year, with a growth rate of 50% per year for the past three years.

The impact is therefore environmental, economic, social, and societal — a complete circular value chain
