In processing residues, Rock Solid maximises their value whilst taking their original characteristics into account. Rock Solid effectuates the following applications depending on residues’ characteristics:
- Direct use, as a replacement for primary raw materials
- Upgrading, followed by replacement of primary raw materials
If upgrading is essential, an analysis of the necessary technologies will be made. For example, this might be through dry processing, wet processing, bio-gradation, immobilisation or by the addition of additives. Furthermore, we find out a location where the upgrading can be carried out: this might be a production site, a depot, a processing plant or the end-user’s site. In order to verify and guarantee the quality and the application, Rock Solid carries out quality controls and certification in line with the European CE marking or other specific guidelines.
