AI Article Synopsis
- Municipal solid waste incineration (MSWI) is a popular method for waste treatment in Europe, producing about 20 million tons of incineration bottom ash (IBA) annually.
- IBA contains valuable materials like ferrous and non-ferrous metals and glass, which can be recovered, depending on the original waste composition.
- The paper reviews different technologies and approaches for recovering non-ferrous metals from IBA, highlighting advancements since the 1990s that have become standard in developed countries.
Article Abstract
Municipal solid waste incineration (MSWI) is one of the leading technologies for municipal solid waste (MSW) treatment in Europe. Incineration bottom ash (IBA) is the main solid residue from MSWI, and its annual European production is about 20 million tons. The composition of IBA depends on the composition of the incinerated waste; therefore, it may contain significant amounts of ferrous and non-ferrous (NFe) metals as well as glass that can be recovered. Technologies for NFe metals recovery have emerged in IBA treatment since the 1990s and became common practice in many developed countries. Although the principles and used apparatus are nearly the same in all treatment trains, the differences in technological approaches to recovery of valuable components from IBA - with a special focus on NFe metals recovery - are summarized in this paper.
