SEOUL, South Korea, Sept. 22, 2026 /PRNewswire/ -- In response to carbon neutrality and the restructuring of global industries, Hyosung Chairman Cho Hyun-joon is accelerating the group's ESG initiatives through proactive investments. Under the strategic leadership of Hyosung Chairman Hyun-Joon Cho, proactive investments have materialized into proprietary technologies and expanded production bases across major affiliates.

Hyosung TNC Expands Low-Carbon Textile Market with Bio-Spandex

As the global leader in spandex market share, Hyosung TNC is aggressively expanding its bio-materials business to address tightening European Union (EU) climate regulations and the textile and fashion industry's shift toward bio-based and recycled raw materials.

The company has built a comprehensive "integrated bio-spandex production system" in Vietnam, encompassing everything from sugarcane-based raw materials to final textile products. Under this structure, the facility in Ba Ria-Vung Tau produces 50,000 tons of bio-BDO annually, which is then processed into bio-PTMG and ultimately manufactured into bio-spandex at the Dong Nai plant.

Produced by fermenting sugars extracted from sugarcane and corn using technology from the American biotechnology firm Geno, bio-BDO can reduce carbon emissions by more than 90% compared to traditional fossil fuel-based products. This bio-spandex maintains conventional elasticity and durability, making it highly applicable for sportswear, swimwear, and denim.

With a total investment of USD 1 billion, Hyosung TNC plans to expand its annual production capacity to 200,000 tons. This strategic move aims to enhance raw material procurement stability and cost competitiveness while significantly reducing transportation-related carbon emissions.

"The bio-business, transitioning from traditional fossil raw materials to plant-based alternatives, will become the core pillar for Hyosung's next 100 years," stated Chairman Cho. "We must strengthen our global market penetration based on this integrated bio-BDO and bio-spandex production system, further elevating Hyosung's premium brand status."

Looking ahead, Hyosung TNC plans to expand bio-BDO applications to include TPU for automotive interiors, biodegradable PBAT resin, and shoe soles, nurturing its Vietnam production base into a comprehensive bio-materials integration platform.
