South Korean producer SK Chemical will establish a Recycle Innovation Centre (RIC) at its Ulsan petrochemical complex, where eco-friendly chemical materials are produced, the firm announced on 18 February.
The company will invest in new pilot facilities for the chemical decomposition of plastic waste to produce recycled BHET (r-BHET), an intermediate raw material in the production of PET and copolyester. SK Chemical aims to start up the depolymerisation pilot facility in 2026 with production capacity of 50 t/yr of r-BHET. The plant is integral to SK Chemical's chemical recycling technology and will be linked with existing commercial copolyester production facilities.
The pilot facility is part of SK Chemical's efforts to process and reuse plastic waste that is difficult to recycle. The facility will validate commercialisation technology for various low-quality plastic waste types that were previously difficult to recycle using conventional methods, including textiles, fibres, films, and automotive parts. Recycling textiles is known to be highly challenging because of the diverse forms and material types mixed in a single garment, including polyester yarn as well as fibres such as cotton and various accessories such as buttons.
SK Chemical previously established a PET chemical recycling plant in Shantou in south China's Guangdong province after purchasing Guangdong Shuye's r-BHET and chemically recycled PET (r-PET) units in 2022 to strengthen its recycled plastic business. The Shantou plant can now produce 70,000 t/yr of r-BHET and 50,000 t/yr of r-PET pellets.
