Two-stage pressurized anaerobic digestion is a promising technology. This technology integrates in one process biogas production with upgrading and pressure boosting for grid injection. To investigate whether the efficiency of this novel system could be further increased, a water scrubbing system was integrated into the methanogensis step. Therefore, six leach-bed reactors were used for hydroly...

Abstract Biohydrogen production in agricultural enterprises is an urgent matter. It appropriate to utilize two methods of biohydrogen production: a thermochemical method – from crop-based biomass and anaerobic digestion (fermentation) animal-based biomass.. use gasifiers for the biore-actors fermentation method. The theoretical potential was established with due regard amount which necessary ut...

Unconventional alternatives such as aerobic and anaerobic effluent from starch industry contain essential nutrients for Btk active ingredient synthesis. Effluent is rich in carbon nitrogen can replace expensive feedstock used during the fermentation process. The main objective of this study was to achieve a biopesticide formulation wastewater (SIW) with high entomotoxicity (UI/ml) larvae compar...

Background: Biogas production from lignocellulosic feedstock not competing with food production can contribute to a sustainable bioenergy system. The hydrolysis is the rate-limiting step in the anaerobic digestion of solid substrates such as straw. Hence, a detailed understanding of the metabolic processes during the steps of hydrolysis and acidogenesis is required to improve process control st...
