Hyosung Begins Commercial Bio-BDO Production in Vietnam
Hyosung has started commercial production of bio-BDO at its Vietnam facility. The bio-based feedstock is used in spandex and polyurethane supply chains, and the move follows tightening material compliance requirements in major markets.
Manufacturing & Process Note: Bio-based BDO shifts the feedstock cost basis for spandex and polyurethane value chains; plant managers should verify fermentation-grade purity and secure offtake lead times before reformulating existing resin or fiber lines.
