Another important step for BST and BSTE towards sustainable manufacturing.
In 2026, we are proud that Bangkok Synthetics Co., Ltd. (BST) and BST Elastomers Co., Ltd. (BSTE) have continuously achieved ISCC PLUS certification from SGS Germany GmbH.
This certification covers operations under the Mass Balance system and raw material management in the Bio, Bio-circular, and Circular categories according to the scope specified in the certificate:
BST : C4 for the production of Butadiene, including operations as a Trader with storage.
BSTE : Butadiene for the production of Styrene Butadiene Rubber.
This achievement reflects our commitment to developing responsible manufacturing processes, using resources efficiently, and delivering products that align with the Circular Economy—because sustainability is driven by all of us working together.
