Hyosung expands bio spandex capabilities

Hyosung TNC has partnered with sustainable materials leader Geno to begin construction of facilities at its plant in Vietnam to produce BIO BDO derived from sugarcane.

The work, which will commence in the second quarter of 2026, is part of Hyosung’s corporate ESG commitment to achieving net zero by 2050 and supporting the wider textile industry to meet evolving sustainability goals.

BDO is the technical name for butanediol, a chemical traditionally made from fossil fuels and a major ingredient in the manufacture of spandex. Through plant-based Geno BDO technology, which ferments sugars derived from sugarcane to replace the fossil raw materials such as coal, Hyosung aims to build on the launch of its range of certified regen BIO spandex products.

The partnership with Geno establishes the world’s first fully integrated manufacturing site for bio-based spandex from renewable raw material to fibre. The project will fast track the production of BIO BDO with an annual capacity of 50,000 tons in the second half of 2026 – with the aim of expanding capacity up to a total of 200,000 tons per year to meet expected industry demand for bio-based spandex.
