 Special interest to BUTALCO is the use of the newly built pilot plant, which is equipped with a safety class 1 approved fermentation room with 4 x 1.5 m³ fermenters.The concept of the plant allows both starch and lignocellulosic based raw materials to be processed.The collaboration will allow BUTALCO to optimise its C5 sugar fermenting and butanol producing yeast strains on a technical scale and produce first amounts of bioethanol from lignocellulose.
