Mineral residues from thermal industrial processes are generally considered waste materials. But not for Rock Solid: we see opportunities to produce new raw materials from waste. Mineral residues from waste-to-energy plants (WtE), steel mills, coal-fired power stations and other thermal processes are converted and recycled in order to be used in the following applications:

  • in the road building and construction industry
  • in the concrete and asphalt industries
  • in landfill constructions
  • in the production of fertilisers

We offer turnkey solutions: from logistics – via upgrading – to the application as a new raw material. Residues can be taken up at any point of the process. Depending on your wishes and requirements, we also offer partial solutions, including logistics, upgrading, quality control, certification, monitoring and application of raw materials.
