Dairy Manure as a Potential Feedstock for Cost-Effective Cellulosic Bioethanol
This study investigated sulfite pretreatment to overcome recalcitrance of lignocelluloses (SPORL) pretreatment and subsequent enzymatic digestibility of undigested dairy manure to preliminarily assess its potential use as an inexpensive feedstock for cellulosic bioethanol production. The sulfite pretreatment was carried out in a factorial analysis using 163 to 197 °C for 3 to 37 min with 0.8% t...
متن کاملPretreatment of Straw Fraction of Manure for Improved Biogas Production
Pretreatment of straw separated from cattle and horse manure using Nmethylmorpholine oxide (NMMO) was investigated. The pretreatment conditions were for 5 h and 15 h at 120 °C, and the effects were evaluated by batch digestion assays. Untreated cattle and horse manure, both mixed with straw, resulted in 0.250 and 0.279 Nm CH4/kgVS (volatile solids), respectively. Pretreatment with NMMO improved...
متن کاملSodium hydroxide pretreatment and enzymatic hydrolysis of coastal Bermuda grass.
Coastal Bermuda grass was pretreated with NaOH at concentrations from 0.5% to 3% (w/v) for a residence time from 15 to 90min at 121 degrees C. The pretreatments were evaluated based on total lignin removal and production of total reducing sugars, glucose and xylose from enzymatic hydrolysis of the pretreated biomass. Up to 86% lignin removal was observed. The optimal NaOH pretreatment condition...
متن کاملBiological Pretreatment and Dry Digestion Processes for Biogas Production
Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process. Additiona...
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...
