Abstract
It is not economical to recycle a number of composite parts through tradi tional routes, such as remelting or chemical recycling, because they either consist of a mixture of polymers or are highly contaminated. A typical example of such waste is the lightweight fraction of shredder waste that accounts for a substantial proportion of the weight of a discarded automobile body. This shredder waste comprises 10-12 % plastics and 6-8% rubber and textiles of the body is eight, with the remainder made up of inor ganic materials such as glass, stones, metals and metal oxides, including rust. This paper discusses a number of alternative techniques for waste disposal, emphasizing processing routes that could be conducted in self-contained plants without any emissions.
