Hyosung TNC begins bio BDO production in Vietnam

Hyosung TNC, a global spandex manufacturer, has commenced production of bio-based 1,4-butanediol (bio-BDO) in Vietnam. Chairman Hyun-Joon Cho has identified bio-based materials as a strategic focus for the group, expanding its innovation portfolio to include regenerative fibres made from recycled PET and corn-based bio spandex. The company's new Vietnamese bio-BDO facility, with an initial capacity of 50,000 metric tonnes per year, aims to increase production to 200,000 metric tonnes annually as demand grows.

The facility produces bio-BDO by fermenting sugarcane-derived sugars, replacing fossil-based feedstocks used in traditional BDO production. This bio-based material maintains the same properties as conventional BDO while enabling the use of renewable resources. Hyosung TNC plans to supply bio-BDO to its Dong Nai operations, where it is converted into PTMG, an essential intermediate for manufacturing regenerative bio spandex.

The company's commitment to sustainability is demonstrated through sourcing and traceability of sugarcane from the VIVE Sustainable Programme, as well as certification of bio-based content under the SGS Environmentally Evaluated Product Scheme. This move aligns with the growing demand from premium fashion brands seeking consistent performance and transparent material sourcing.

Hyosung TNC's venture into bio-based spandex production is part of a broader strategy to supply bio-based chemical intermediates for various applications, including automotive interiors and biodegradable plastics. The company's investment in Vietnam has the potential to strengthen economic ties between South Korea and Vietnam.
