Automotive Shredded Residues (ASR) result from the reclamation process of recyclable ferrous and non-ferrous metals. The primary source of recyclable materials comes from automobiles, trucks, buses and common household appliances such as washers, dryers and refrigerators. According to estimates from the automotive industry only in the United States about 2 billion pounds of ASR are generated annually.

ASR generally consists of a mixture of plastics, rubber, glass, wood products, cloth, paper, foam, dirt, and electrical wiring. Average calorific value is 19-21 MJ/kg. Some streams after shredder can have high plastics content and the calorific value may rise to 40 MJ/kg. It is obvious that incinerators have a big problem to handle ASR.

The industrial ASR pyrolysis systems implement general MPSC scheme, producing pyrolysis gas followed by generation of electricity. ASR pyrolysis facility is characterized by high efficiency power generation, additionally recycling the non-oxidized metals. As example daily pyrolysis treatment of ~400 tons ASR with calorific value ~21 MJ/kg supplies about 10 MWe to the grid.
