PROJECT DETAILS:
To valorize decontaminated soils previously impacted by organic and inorganic contaminants, Northex Environnement is investigating their potential as functional raw materials. A key pathway under evaluation involves the generation of two well-defined granulometric fractions, intended for integration as input materials in the formulation of hygienic cat litter products. Achieving the requisite performance and quality criteria will necessitate process refinement to ensure that the recovered fractions meet the physicochemical specifications typically required for such applications.
The primary objective of the project is to optimize the soil treatment process to yield granular fractions that exhibit both physical and chemical compatibility with other constituents commonly employed in cat litter production. Due to the hygienic nature of the final product, quality assurance protocols will also be revised and aligned with relevant sanitary and safety standards.
This initiative offers multiple benefits:
A) It reduces the dependency on virgin raw materials, notably bentonite, whose extraction, processing, and transportation have significant environmental footprints;
B) It enables the upcycling of remediated soils into value-added products, thereby supporting the advancement of a regional circular economy and enhancing the sustainability of soil remediation practices.
