A PET palack és egyéb poliészter hulladékok újrafeldolgozása, újrahasznosítása

Abstract

The scientific definition of polyethylene terephthalate (PET) changed for polyester in the common language. It was first manufactured in 1928 and the production of the fibre version started in 1941. Nowadays, 70% of artificial textile raw materials are polyester fibres and a significant amount of plastic waste is generated at the end of the life cycle of polyester clothing and other end products. The injection moulding process introduced in the 1970s made it possible to design and produce three-dimensional objects, and this resulted in the spreading of light, transparent, resistant and non-fragile PET bottles. Given that the degradation of PET is more than 450 years, the increase of recycling and reprocessing is an urgent pressure.
