Industrial waste streams gain new life

Through the MaRes programme, VITO and other Flemish partners look for smart ways to add value to industrial residue streams. To this end they are implementing a 'zero waste' concept: every part of the waste stream is reused.

The more resources we use, the smaller the supply and the higher the demand. Six Flemish industrial companies want to break that vicious circle. To do so, they founded the consortium MaRes (Materials from solid and liquid industrial process Residues) along with KULeuven, UGent and VITO.

Together, the MaRes partners developed a ready-made package that links every possible industrial waste stream to the optimum treatment method. Their goal is to recover every part of the waste stream, from metal slag to incineration residues, in the best way possible. These residue streams contain plenty of valuable metals, which can be filtered out through magnetic separation. Once the residue is cleaned, it can be reused as a resource for construction materials.

VITO's role

As a MaRes partner, VITO is using its expertise in the application of several valorisation techniques:

  • filtering valuable resources from watery waste streams;
  • pre-treating solid industrial waste streams through physical or magnetic separation. These processes are linked to applied software;
  • treating metal slag with carbon dioxide (carbonatation) to create new construction materials.
