Automation of Plastic Recycling – A case study
2009 (English)In: Proceedings of EcoDesign 2009, Sapporo, Japan, Springer, 2009, 935-940 p.Conference paper (Refereed)
Plastic recycling is an increasingly important issue intoday’s society. The number of plastics and theirvariation with additives has increased lately, affecting inturn the possibilities for plastic material recycling.However, trends in e.g. Japan show a reduction in thenumber of plastics used in e.g. household appliances.This reduction has been put into force in order to easeplastic recycling for those kinds of products.In Sweden, more efforts are put on collecting plasticfor material recycling. The intention for doing this is tohave more plastic material recycled rather thanincinerated and energy recovered. This paper deals witha conceptual investigation and development of anautomatic plastic recycling plant in Sweden. In order toreach a recycling plant that fulfills required technical andeconomic specifications, a large investigation of existingtechniques was performed. This investigation revealedmany techniques described in research, but also whichtechniques that were used by recycling industry today.The results of these studies became a conceptual andpotential well-functioning material recycling plant forplastics which is fully automatic. However, the focus ofthis development has been to sort out and materialrecycle the most common plastics, namely polyetene(LDPE and HDPE), polypropylene (PP), polyethylene(PET), polyvinyl chloride (PVC) and polystyrene (PS)whereas the other plastics have been sorted out forenergy recovery. Having these delimitations, a goodrecycling process plant can be achieved.
