We are Rock Solid


Mineral rest streams from industrial thermal processes are generally regarded as a waste product, but not so by Rock Solid. For us, these rest streams are new raw materials for different uses.

About us


Since its establishment in 2006, Rock Solid has been a key player in the waste-to-energy plant (WTEP) bottom ash market. Applying bottom ash as a building material in groundwork and civic engineering projects results both in a reduction of the use of natural raw materials and in a cost reduction for contractors and waste-to-energy plants.
