Reclaiming fuel oils from waste plastics

High Performance Plastics, January, 1993

The world's first technology for reclaiming fuel oil from chloride-based plastics has been developed by researchers at the Environmental Engineering Laboratory of Toshiba Corp, Tokyo, Japan. Because chlorides release poisonous hydrogen chloride gas (HCl) during conventional heat decomposition, fuel oil reclamation has been prevented until now, says Toshiba. However, the new technology can be applied to the thermoplastics that decompose when exposed to heat. This category includes polyvinyl chloride (PVC), acrylonitrile-styrene copolymer, acrylo- nitrile-butadiene-styrene (ABS) copolymer, polyethylene and polypropylene.

In conventional fuel reclamation processes, plastics are put into a reaction chamber and heated to a gaseous state. On cooling, the fuel oil is...
