Our activity

tri.jpgTerralys contributes to sustainable development through the re-use and return to the soil of organic waste.

The tailored solutions and expertise offered by our teams are feasible in terms of both cost and required investment.

Biological re-use has been our business here at Terralys for over 30 years. TERRALYS takes charge of the waste at source, it organises the transport and all aspects from processing through to the finished recovered product. We also work upstream with the producers of organic waste to guarantee a better quality of waste entering our sites.

Allied with the R&D expertise of Suez Environnement, Terralys has the technical expertise to ensure it very efficiently reacts to major problem issues, such as odour management.
Moreover, the skills of its engineering division are reflected in the construction of treatment plants designed specifically to handle waste from local authorities or industry.

How is biological re-use from my waste optimised?

  • Increasing awareness amongst the public to improve sorting of waste and composting by individuals. Terralys supports local authorities in this endeavour.
