Asahi Kasei: Production of S-SBR using sustainable butadiene
Asahi Kasei will produce solution-polymerized styrene-butadiene rubber (S-SBR) using butadiene derived from plastic waste. The company concluded an agreement with Shell Eastern Petroleum Ltd. on 23 November 2021, regarding the supply of butadiene derived from plastic waste and biomass.
Asahi Kasei plans to begin producing and marketing of sustainable solution-polymerized styrene-butadiene rubber using the sustainable butadiene at its plant in Singapore by the end of fiscal 2021 in March 2022.

Shell will produce sustainable butadiene by mass balance method in two ways at Bukom, Singapore. (The mass balance method is a globally applied method to calculate the share of sustainable raw materials for individual products in a mix of sustainable and petroleum-derived raw materials.) The first is a method of converting plastic waste into pyrolysis oil and feeding it to the naphtha cracker, the second is using bio-feedstock as a naphtha cracker feed.
