MSWI ash can contain several metals that EU has listed as critical. In addition, the mineral fraction of ash is an interesting raw material for low CO2 cementitious binders.
Our SUSRES project focuses on processes that enable efficient and throughout utilization of MSWI ashes through, 1) mechanochemical treatment, 2) bioleaching, and 3) development of cementitious binders. The project focuses on the interconnection of different processing steps to allow fluent transfer of resources from waste stream to products. The project combines high value utilization (metal recovery) to high volume utilization (mineral residue utilization) to develop economically viable solution for MSWI ash utilization.
The utilization of MSWI residues as a source of critical metals and as cementitious binders reduces the consumption of non-renewable natural resources, lower CO2 emissions related to material processing, as well as decrease the potential hazards related to waste disposal.
