Within the scope of the UFOPLAN-project „Possibilities of a resource-efficient recycling economy by further extraction of raw materials from solid combustion residues from the treatment of municipal solid waste”, different options were evaluated in order to optimize ash/slag discharge systems and the processing of slags/bottom ash. The focus was put on the influence of the discharge in the municipal waste incineration, short MSWI, in order to compare wet and dry discharge.

The research on the current state of knowledge and state of the art in the field of MSWI shows, that the combination of wet discharge and subsequent mechanical processing, common in Germany, are already leading to good results in terms of metal reclamation.
