Methanization potential of anaerobic biodigestion of solid food waste [PDF]
Revista Brasileira de Engenharia Agrícola e Ambiental, 2018 Anaerobic biodigestion of solid and semi-solid wastes has been widely used for the treatment of these residues and methane production; however, during the process (more specifically in the acidogenic phase), there is a tendency of pH reduction, an ...

Anaerobic co-digestion of rabbit manure and sorghum crops in a bench-scale biodigester [PDF]
Bioresources and Bioprocessing, 2020 Any type of biomass can be used as substrate for biogas production, but the performance of the biodigestion depends on the composition of the feed, and no direct extrapolation of the yield of the process from one substrate to another can be made. In this
