A new industrial process will be realized for a (pre) treatment of halogens containing materials to obtain "clean" fuels and purified noble metal containing residues from a process integrated separation of halogens. Possible feeds are electronic devices (shreddered mobile phones or computers) or separated fractions like circuit boards. The reactor concept (pilot scale prototype) - a gas tight cascade of rotary kilns with separate conveyor screws, metal based bulk goods and gas tight connectors - has been developed in the former and still running project "Halocleanconversion-G1RD-CT-1999-00082". The results show, that it is possible to generate oils with a halogen content in the ppm-range and a PCDD, PCDF concentration below detection limit. Noble metals can be concentrated easily in a residue fraction of 5 wt-% of the feed, containing gold up to 2.2 wt-%. Furthermore, a European-Life-Cycle-Analysis-Centre for polymeric materials will be founded.
