Recycling Potential of Polymers 91A123

In order to reduce the volume of waste in general and of shredder waste from the disposal of scrap cars, the German Federal Government has prepared a draft regulation, which will be implemented unless the automotive industry and the distributors of imported cars take action on their own to achieve these objectives. The regulation provides that the car manufacturers are fully responsible for the environmentally controlled disposal of scrap cars. The return of scrap cars to the work industry must be free of change for the last owner. A nation-wide network for the return of scrap cars must be implemented by end of 1993. To reduce the amount of shredder waste the automotive industry is expected to practice recycling on non-metallic materials. Facilities required for thermal treatment of residues, which cannot be recycled, are to be installed on account of the originator, i.e. the automotive industry. The paper deals with the recycling potential of the mostly used thermoplastics, considering economical and logistical aspects for collecting and recycling of these materials for future automotive use. Examples demonstrate, that the possibility of recycling does not depend upon material only, but on design of parts, avoiding combinations of chemically incompatible materials which cannot be separated easily.
