Bio-methane Generation Supply-cost Curves from Manure Digestion as Substrate

C. Bidart, A. Gordon, M. Flores & P. Loubiés
Energy and bio-methane potential derived from livestock residues of all major groups of stock-raising animals, i.e. cattle, pigs, sheep-goats and poultry, were evaluated for a studding area in Chile. The calculations were based on geographical and statistical data, which typically includes population of animal groupings, availability factors, and degree to which the animals were stabled. This data was then processed through a methodological approach that allowed for the determination of potential primary and secondary energy...
