Abstract

Water extraction of raw chicken manure elevated the carbon-to-nitrogen ratio 2.7-fold, i.e. from 7.48 to 19.81. The treated chicken manure (T-CM) thus became suitable for biogas fermentation as monosubstrate. Improved methane production was achieved in co-fermentations with either maize silage (24% more methane) or corn stover (19% more methane) relative to T-CM monosubstrate. The standardized biogas potential assay indicated that the methane yields varied with the organic loading rate between 160 and 250 mL CH4/g organic total solid (oTS). Co-fermentation with maize silage was sustainable in continuous anaerobic digestion for at least 4 months.
