TECHNOLOGY | PET RECYCLING

per year of old PET bottles. It plans to have the plant operating around the end of 2024. In March, it signed an Expression of Intent agreement with PET producer Equipolymers, which could host the unit on its site in Schkopau, Germany. In January, Eastman Chemical Company announced plans to build one of the world’s largest plastic-to-plastic molecular recycling facilities at its site in Kingsport, Tennessee, US. Using methanoly- sis-based technology developed by Eastman, it will convert polyester waste. Eastman is already lining up supplies, including material from old polyester carpets. The facility, which is expected to be mechani- cally complete by year-end 2022, will contribute to the company achieving its ambitious sustainability commitments for addressing the plastic waste crisis, which includes recycling more than 500m pounds of plastic waste annually by 2030 via molecular recycling technologies. Switzerland headquartered start-up Gr3n said in December that it had raised funds from an initial investor that would help it towards its goal “to become the world leading supplier of recycled PET and polyester.” The company says it has developed the first economically sustainable and industrially viable process for breaking down any type of PET
and polyester plastic into PTA and MEG monomers. A demonstration plant with an inlet capacity of 60 kg/h, located on the premises of NextChem in Chieti, Italy, is currently under construction. This is part of the EU-sponsored Demeto project (Demeto is an acronym for depolymerisation by microwave technology). SABIC said in March that since the introduction of LNP Elcrin iQ materials in late 2019, it has helped divert more than 100 million single-use 16.9 oz. (50 cl) PET water bottles from landfills and incinerators, converting them in a chemical recycling process into polybutylene terephthalate (PBT) materials. Huntsman also operates chemical recycling, but in its case, it is converting old PET bottles into polyurethane polyester polyols. It has two plants, one in Houston, Texas, US, (running since 2014, processing the equivalent of around 1bn 500-mL bottles per year to yield around 26,000 tonnes per year of polyols), and one in Taiwan (which opened last year, and which has a declared output of 22,000 tonnes per year).
