Overview in Europe
Bottom ash (BA) from municipal solid waste incineration (MSWI) has a high potential for the recovery of valuable secondary materials due to the conditions of incineration.
New directions with BA
Recovery of more metals and recovery of metals from a very fine fraction e.g. < 3 mm to 4 mm. Upgrading metal qualities.
Products/Residues
Non-ferrous metal, scrap iron, precious metals, stainless steel, meatballs (Cu-Fe engines, etc.), organics and aggregates.
Sustainability
Treatment of MSWI bottom ash (BA) helps to save resources in the sense of recovering valuable metals while simultaneously minimizing the environmental risk as a result of upgrading the quality of the residue fraction.
