South Korean spandex maker Hyosung TNC has commenced commercial production at its $1 billion bio-BDO plant in Ho Chi Minh City, Vietnam. The plant has an annual production capacity of 50,000 tons, with infrastructure in place to expand to 200,000 tons as demand grows. This facility completes an integrated supply chain that converts sugarcane-based raw materials into spandex, replacing fossil-based feedstocks used in conventional BDO production through the fermentation of sugars extracted from sugarcane.
