Alternative feedstock supplementation can add value for lignocellulosic bioethanol production from wheat straw
39th Symposium on Biotechnology for Fuels and Chemicals
In the current study whey, whey permeate, beer production mash, deep litter, potato pulp, rape seed press cake, and saw dust are all investigated as feedstock supplements on 2G bioethanol production of wheat straw. These biomasses can all be found in close proximity to a projected full-scale 2G ethanol plant in Denmark.
The impact of including these alternative biomasses is assessed on the basis of composition, high dry matter enzymatic hydrolysis yields, fermentations yields, and assessment of selected inhibitors and potential fermentation nutrients. The impact of different blend-in ratios for blending in the alternative biomasses in a wheat straw based ethanol production will also be presented, while the optimal point of including the different biomasses in the production will be discussed.
