Ethanol production from mixtures of wheat straw and wheat meal
BACKGROUND Bioethanol can be produced from sugar-rich, starch-rich (first generation; 1G) or lignocellulosic (second generation; 2G) raw materials. Integration of 2G ethanol with 1G could facilitate the introduction of the 2G technology. The capital cost per ton of fuel produced would be diminished and better utilization of the biomass can be achieved. It would, furthermore, decrease the energy...
متن کاملSeparate hydrolysis and co-fermentation for improved xylose utilization in integrated ethanol production from wheat meal and wheat straw
BACKGROUND The commercialization of second-generation bioethanol has not been realized due to several factors, including poor biomass utilization and high production cost. It is generally accepted that the most important parameters in reducing the production cost are the ethanol yield and the ethanol concentration in the fermentation broth. Agricultural residues contain large amounts of hemicel...
متن کاملCultivar variation and selection potential relevant to the production of cellulosic ethanol from wheat straw
Optimizing cellulosic ethanol yield depends strongly on understanding the biological variation of feedstocks. Our objective was to study variation in capacity for producing fermentable sugars from straw of winter wheat cultivars with a high-throughput pretreatment and hydrolysis well-plate technique. This technique enabled us to estimate cultivarrelated and environmental correlations between su...
متن کاملCombined production of bioethanol and biogas from wheat straw
Due to the problems with environment and green house gases more biofuels as bioethanol and biogas needs to be produced to reduce the problems. Wheat straw as raw material is a good choice for ethanol and biogas production since wheat is the most produced crop in Sweden and the whole Europe and it isn’t competitive to food. In this study three different options for pretreatment of wheat straw, c...
متن کاملInfluence of high gravity process conditions on the environmental impact of ethanol production from wheat straw.
Biofuel production processes at high gravity are currently under development. Most of these processes however use sugars or first generation feedstocks as substrate. This paper presents the results of a life cycle assessment (LCA) of the production of bio-ethanol at high gravity conditions from a second generation feedstock, namely, wheat straw. The LCA used lab results of a set of 36 process c...
