Abstract
In this article, we have reviewed how polyethylene terephthalate can be recycled into value-added products so that it can be used as a raw material for coating applications.
Highlights
In the modern era of globalization, plastics are an integral part of our daily life; from our morning toothbrush to night dinner table, plastics are everywhere
There are already various wellestablished methods developed by researchers & scientists to synthesize value added products from polyethylene terephthalate (PET) waste and there is a huge scope for translation of these technologies into industry
To encounter the challenges involved with the recycling processes, especially in separation, purification and processing steps proper expertise and supervision is recommended along with advanced reactor designing, appropriate process control measures and all necessary safety precautionary measures
Summary
As a consequence, 2.41 million tons of these robust waste materials enter into our ecosystem every year To overcome this problem, researchers focus on synthesis of novel biodegradable synthetic polymers as well as sustainable strategies for recycling of these plastics so that they can enter into a circular economy. North America with a market share of 20.5% followed by Western Europe with 17.9% market share.[5] It is expected that within the time span of 2020–2025 the PET based packaging industry will get a huge boost in the countries of the Middle East and Africa due to their growing economy and emerging socioeconomical status These statistics suggest that this huge consumption of PET produces a massive amount of post-consumer plastic waste, which is a serious threat from the environmental point of view. We have highlighted that the existing challenges involved with the upscaling of these processes in industry as well as their probable solutions, so that these recycled products can be used in a sustainable and economically feasible way, which will lead to a closed-loop sustainable ecosystem for a cleaner world
