Chemicals group BASF has said new variants of the butanediol (BDO) and its derivatives that it produces at its plant in Ludwigshafen will offer customers a lower carbon footprint.

BDO is a key ingredient of polytetrahydrofluoride, which is used extensively in the production of elastane fibres for use in swimwear, sportswear, underwear, stretch jeans and other garments.
