Hyosung’s Backward Integration Into Raw Material For Spandex
Hyosung is initiating a backward integration project and is investing in producing bio-Butanediol (BDO), which is a chemical, used as a raw material for PTMG, which is used to make spandex fibre.
This was announced by Hyun-Joon Cho, Chairman of Hyosung who added that the company is investing US $1 billion to establish a 200,000 tons per year bio-BDO plant in Vietnam
Hyosung received investment approval for the project from the Ba Ria-Vung Tau Provincial Government last month to be set up in Phu My 2 Industrial Park in southern Vietnam.
Bio-BDO is manufactured by fermenting sugars derived from sugarcane, replacing traditional fossil raw materials such as coal by 100 percent.
The South Korean company has chosen Geno’s proven technology, which enables Hyosung to unlock and fast track production of bio-BDO in the first half of 2026.
According to a Hyosung press release, from raw material to fibre, Hyosung has established the world’s first fully-integrated production system for bio-Spandex
Notably, the South Korean company is the first in the world to establish a vertically integrated production system for bio-spandex, from raw material to fibre.
Hyosung will produce bio-BDO at its factory in Ba Ria-Vung Tau Province, manufacture PTMG at a nearby factory in Dong Nai and then use this to produce Regen Bio spandex at the Dong Nai Spandex factory.
