Jun 10, 2020 · In general, pretreatments improve anaerobic digestion of the lignocellulosic content of animal manure and, therefore, increase methane yield. The objective of this research is to present a review of the current technologies and pretreatments used in the fermentation of cow, pig and poultry manure.

Enhanced degradation of glucocorticoids, a potential COVID-19

Waste activated sludge (WAS) and animal manure are two significant reservoirs of glucocorticoids (GCs) in the environment. However, GC degradation during anaerobic digestion (AD) of WAS or animal manure has rarely been investigated. In this study, co-fermentation of WAS and animal manure was conduct

Bioenergy production from chicken manure: a review - Springer

Jun 12, 2023 · Tylosin concentration exceeding 167 mg/L in the manure highly deteriorated the biomethane productivity due to an accumulation of acetate and propionate in the fermentation medium. Anaerobic co-digestion of 10% of primary sludge to 90% of chicken manure increased the biogas yield up to 8570 mL/g volatile solids.
