Abstract |
Due to the increasing production of plastic soft drink bottles, accompanied by the accumulation of plastic waste in landfills, our society is encouraging the development of recycling industries around the world, with a special focus on recycling post-consumer PET (polyethylene terephthalate, the world's third most dominant plastic) for food contact applications (i.e., for single-use items). Plastics have indeed become a threat to the environment because of the lack of recycling technologies, which could instead enable the production of high-quality polymers from scrap materials, at an equal or lower cost compared to the production of the corresponding virgin polymer from crude oil. PET has a great recycling potential if compared to the other most diffused plastics, and it can be treated in many different ways. In this chapter, the very broad spectrum of all the available technologies for PET recycling is presented (from the zero-order to the fourth-order recycling) with particular attention to mechanical and chemical recycling. Indeed, the former is currently the best available technology for PET recycling at the industrial level, while the latter represents the best perspective for PET recycling in terms of circular economy, allowing to get back the monomer building blocks from complex waste materials and using the monomers to produce a new recycled polymer. Advantages and disadvantages of the current state of the art are highlighted, aiming to identify the viability of every process at the industrial scale. |
