MOSCOW (MRC) -- Toyo Engineering and SCG Chemicals in Thailand entered into a MOU relating to the joint collaboration for improving the process of turning mixed post-consumer plastics into recycled feedstock for petrochemical businesses, said Hydrocarbonprocessing.
The process is owned by Circular Plas (CirPlas), which SCG Chemicals hold a 60% stake. CirPlas has already operated the demonstration plant for the advanced recycling process in Rayong province, Thailand. In September 2021, the process using the advanced recycling technology received the International Sustainability and Carbon Certification or ISCC PLUS. This certificate is issued to organizations with sustainable management and development across the supply chain with SCG Chemicals as the first in Thailand to be certified in the advanced recycling category. SCG Chemicals and CirPlas are planning to increase the capacity of the demonstration plant, and CirPlas and TOYO execute the joint collaboration of exploring scale-up for commercialization.
The advanced recycling technology uses a catalyst, so the recycling process is in low temperatures. This reduces energy consumption and promotes environmental-friendliness. By recycling post-consumer plastics into feedstock for virgin plastic resin, it can contribute to solve the problem of plastic waste not only in Thailand but also in other countries.
As MRC wrote previously, SCG Plastics, part of SCG, took its high density polyethylene (HDPE) plant off-stream for a maintenance turnaround on November 26, 2019. It remained under maintenance until December 14, 2019. Located in Map Ta Phut, Thailand, the plant has a production capacity of 200,000 mt/year.
Ethylene and propylene are feedstocks for producing polyethylene (PE) and polypropylene (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 2,265,290 tonnes in the first eleven months of 2021, up by 14% year on year. Shipments of all grades of ethylene polymers increased. At the same time, PP shipments to the Russian market were 1,363,850 tonnes in January-November, 2021, up by 25% year on year. Supply of homopolymer PP and block-copolymers of propylene (PP block copolymers) increased, whereas supply of injection moulding PP random copolymers decreased significantly.
