What is bottom ash?

Bottom ash is the largest residue fraction after incineration municipal solid waste (MSWI) and it mainly consists of minerals, glass and ceramics, but it also contains 1-3% non-ferrous metals and 5-15% scrap iron. A Swiss person produces approximately 100 kg of bottom ash per year.

What are shredder residues?

Usually in the recycling of Cars, electronics and electrical household aids the materials are shredderd and afterwards separated by air. The result is a Shredder-Light-Fraction (SLF) and a Shredder-Heavy-Fraction (SSF). SSF contains the bigger and densier material and contains most of metals, but also in the SLF are still some metals which can be separated from the plastics. Both fraction, SLF and SSF, can be processed in the supersort®metal plant.
