Waste activated sludge (WAS) is the most yielding byproduct in municipal wastewater treatment plants (MWTPs), and its disposal poses secondary pollution that severely threatens the environment.

"Can we recover something potentially of higher value than biogas?" he asked. He and his team looked at short-chain volatile fatty acids (VFA), a common intermediate compound for many materials, ...

This research assessed the effect of decoupling hydraulic retention time (HRT) and solid retention time (SRT) on the production of volatile fatty acids (VFAs) via anaerobic fermentation of beet ...

Plant secondary metabolites (PSMs) can potentially reduce ruminal methane formation. However, related to differences in their molecular structures, it is not yet clear what causes an anti-methanogenic ...

Volatile fatty acid separation from biowaste. Cattle manure is anaerobically digested in a bioreactor, and the resulting broth is processed with redox-mediated electrodialysis. The volatile fatty ...

Many sewage treatment plants are equipped to process waste using anaerobic digestion, in which the sewage sludge is held in an oxygen-free chamber to ferment and break down. As part of that ...
