Effluent solids recirculation to municipal sludge digesters enhances long-chain fatty acids degradation capacity

Biotechnology for Biofuels, 2021
Background Slow degradation kinetics of long-chain fatty acids (LCFA) and their accumulation in anaerobic digesters disrupt methanogenic activity and biogas production at high loads of waste lipids.

Markets Mitigate Land‐Use Competition From Energy Crops and Increase Farm Revenues

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large‐scale biomass production for land use, crop production, and market outcomes under mature market ...
