From polymer waste to potential main industrial products: Actual state of recycling and recovering

Abstract

lastics have become widely used materials in everyday life due to their special properties such as durability, easy processing, light-weight and low-cost of production. However, because of their stable and non-biodegradable nature, postconsumer plastics become an issue to the environment. The growing amounts of waste are generated, as plastic products are commonly used only once before disposal. The alternatives of practical techniques for solid waste management are: redesign, reprocessing and recycling. Even thus recycling is not the most profitable technique for the treatment of plastic waste it should be constantly developed. The recycling of plastic waste helps to conserve natural resources due to polymeric materials are made from oil and gas. There are four main recycling methods: reuse, mechanical recycling, chemical recycling and energy recovery. Mechanical recycling turns polymeric waste into new polymer products when energy recovery process releases the energy contained within plastics through combustion and chemical recycling converts waste polymers into feedstock for chemicals/monomers/fuels production. Nowadays chemical recycling of plastic waste is the most noteworthy of polymer recovery technique. This manuscript presents a literature review on chemical recycling methods of various polymers, such as polyethylene (LDPE or HDPE), polypropylene or mixture of this polymer waste, poly(ethylene terephthalate), polycarbonate, polyurethane etc. We described the effect of the reaction parameters on obtained products, used catalysts and agents and used equipment for specific methods of chemical recycling. In this way, the state of the art of the chemical recycling methods of several polymers is presented.
