A microwave-assisted alkaline hydrolysis for an economically viable recycling process of PET
01.
Identification
The Solution aims at providing a sustainable, and profitable option for recycling polyester, with a particular focus on what mechanical recycling is not able to treat. This Solution relies on microwave-assisted alkaline hydrolysis to go back to terephthalic acid and ethylene glycol, saving up to 60% of CO2 emission compared with the existing production processes. This allows us to go back to what is normally used to produce PET and polyester fibers with a purity as high as the one from fossil fuels. Re-polymerizing the molecules it is possible to obtain a new polyester without using oil (at least 0 kg of petroleum naphtha per Kg of PET produced) and with the same quality (i.e., physical-mechanical properties, scrap rate, etc.).
