[PR Newswire APAC](https://en.prnasia.com/story/552268-0.shtml) reported the milestone on October 19, 2026.\n\n## Hyosung TNC's Vietnam Bio-BDO Plant\n\nHyosung TNC is a South Korea-headquartered subsidiary of Hyosung Group and the world's largest spandex/elastane manufacturer, producing CREORA spandex, MIPAN nylon, performance polyester, and regen recycled and bio-based fibers for apparel, swimwear, denim, outdoor and personal hygiene brands.\n\nThe Vietnam facility produces bio-BDO by fermenting sugars derived from sugarcane, replacing fossil-based feedstocks used in conventional BDO production. The company said the material is chemically identical to conventional BDO and maintains the same stretch, recovery and quality in finished spandex fiber.\n\nBio-BDO is supplied to the company's Dong Nai operations and converted into PTMG, a key intermediate used to manufacture regen BIO spandex, also known as elastane. Connecting these stages across southern Vietnam is designed to strengthen supply reliability, improve production efficiency and reduce transportation requirements.\n\n\"We have established an integrated production system that connects bio-based raw materials with finished spandex fiber,\" Chairman Hyun-Joon Cho said. \"This will be a core pillar of Hyosung's next century.\"\n\nSugarcane sourcing and traceability are verified through the VIVE Sustainable Program, while bio-based content is certified under SGS's Environmentally Evaluated Product Scheme. Hyosung TNC also plans to supply bio-based chemical intermediates for thermoplastic polyurethane used in automotive interiors and polybutylene adipate terephthalate, a resin used in biodegradable plastics.\n\n## Hyosung TNC's Bio-BDO Investment Records\n\nHyosung TNC began supplying bio-based 1,4-butanediol from the new Vietnam plant in May 2026 as it geared up for industrial-scale production, according to akta.pro [company records](https://akta.pro/company-data). The same records show the plant has an initial annual capacity of 50,000 tonnes with infrastructure designed to scale up to 200,000 tonnes per year, backed by a nearly $1 billion integrated investment spanning sugarcane to Bio Spandex.\n\n## Earlier Hyosung TNC Bio-Material Steps\n\nHyosung TNC announced at the Sourcing Journal Fall Summit in October 2026 its expansion of bio-based spandex, investing up to $1 billion in a Vietnam facility using BDO from sugar cane, with a partnership with Czarnikow cutting carbon emissions by an estimated 45% versus conventional spandex, WWD reported.\n\nHyosung TNC began commercial production at a $1 billion bio-BDO plant in Ho Chi Minh City, Vietnam, producing 50,000 tons annually from sugarcane, Naver reported in September 2026. Hyosung TNC established an integrated bio-BDO to bio-spandex production system in Vietnam, producing 50,000 tons of bio-BDO annually, Yahoo reported the same month.\n\n## Hyosung TNC's PERFORMANCE DAYS Schedule\n\nHyosung TNC is sharing insights into bio-based spandex adoption at PERFORMANCE DAYS in Munich on October 13-14, the Textile Exchange Conference in Vancouver on October 12-16, and Functional Fabric Fair in Portland, OR, on October 27-28.\n","publisher":{"name":"News for Agent","url":"https://newsforagent.com"}}
