Belgarena has spearheaded the development work of ROTON Environment Group in Wallonia for more than twenty years.

Its main aim is to decontaminate and recover slightly polluted soil from civil engineering and land remediation sites.

Belgarena also processes foundry sand and other inert waste materials whilst continuing to expand its activities in the production and logistics of materials for the building and public works (BPW) sector.

Besides the actions to protect and bolster wildlife on Saint-Jacques mining tip that are being conducted by SETSJ, Belgarena is developing and supporting specific ecological actions on the Farciennes site, including within the Sambre river contract.
