An Assessment of “Pyrolysis” as a Resource Recovery Option for Automobile Shredder Residue

Pyrolysis, the chemical cracking of organic materials such as polymeric materials represents an innovative technology to recover resources contained in automobile shredder residues (ASR). In this study the technical capabilities, economic viability and environmental impact of pyrolysis as applied to ASR has been investigated. Based upon data provided by pyrolysis equipment suppliers, the pyrolysis of ASR appears to be a viable option to deal with the growing quantities of this material currently being produced. However, the selection of the most appropriate pyrolysis technology is dependant upon local needs and requirements.
