Reusing most of the materials

Thermal waste treatment produces residues which can be either reused or landfilled. The principal components are slags and ashes, consisting mostly of non-combustible waste constituents such as glass, minerals or scrap metals. Flue gas cleaning also forms reaction products. The volume and nature of the residues produced depend mainly on the composition of the waste and the process used in the particular treatment concept. With an intelligent secondary treatment process, large parts of these materials can often be reused.
