BioAmber is seeking a $360 million loan guarantee from the US Department of Energy (DOE) to build its second plant, which will be located in the US. The proposed US facility will be over six times the size of the Sarnia plant - with annual capacity of 70,000 tons of bio-based 1,4-butanediol (BDO), 24,000 tons of bio-based tetrahydrofuran (THF) and 60,000 tons of bio-based succinic acid.
