Construction of a plant for the production of recycled plastics using chemical depolymerisation and Solvoli technology – funded by the European Union – NextGenerationEU
Plasta Rei took part in the MASE call for proposals under the PNRR funds – NOTICE M2C.1.1 I 1.2 Action Line C “Construction of new facilities for the recycling of plastic waste (through mechanical and chemical recycling, and Plastic Hubs), including marine plastic litter”, funded by the European Union – NextGenerationEU 1*.
PROJECT TITLE: Construction of a plant for the production of recycled plastics using chemical depolymerisation and solvolysis – funded by the European Union – NextGenerationEU
The aim of the investment is to construct a plant for the production of recycled plastics from plastic waste (uncleaned post-consumer PET, regardless of shape, colour or size) using an industrial chemical depolymerisation process based on glycolysis. The proposal involves the conversion of a solution-based polymer production plant into a glycolysis depolymerisation plant, followed by a purification stage. The process flow will be as follows: the plastic waste supplied by sorting centres will be pre-treated to make it suitable for the depolymerisation process. It will then be fed into the glycolysis reactor, where, in the presence of ethylene glycol and catalysts, the PET polymer chains will be broken down to form an intermediate monomer, BHET, and low-molecular-weight oligomers. The reaction products will then be filtered and purified to remove unreacted PET and impurities. The products obtained from the chemical depolymerisation process (BHET and PET oligomers), once purified, will be reconverted by polycondensation into PET with a degree of crystallinity and a molecular weight suited to the requirements of market applications (e.g. bottle-grade).
