Plastic is an essential material in our daily lives that has multiple functions: food packaging bottles and jars, insulators, microchips in phones and computers, textile industry and so on. The world’s annual consumption of plastic materials has increased from around 5 million tonnes in the ‘50s to nearly 300 million tonnes in 2020. Due to plastic’s resistance against degradation and its increased production in industry, the issue of plastic pollution has evolved to become a menace to global ecology. Therefore, there is an urgent need to resolve these environmental issues that minimise the importance of these materials that play an important role in our daily lives. All these recycling approaches have limitations because the PET can only undergo a finite number of processing cycles before their properties are significantly compromised ends up in the landfills or is incineration, being the source of others pollutants. However, PET could be recovered through chemical recycling, we could save the natural resources and the prices of polymers would be lower. RECYCLE propose a simple solution, to heterogeneously catalyse PET depolymerisation using surface modified flexible materials, in which 2D malleable flakes/sheets are surface modified by strong acidic functionalities, like sulfonates.
