Generation of pig slurry, in those areas with a high concentration of pig farms (e.g. Catalonia and Aragon), became an environmental problem but also constitute abundant resource for energy-recycling. The slurry potential as a substrate for anaerobic fermentation is low, however this performance can be improved by synergic combination with other substrate as agro-industrial by-products. The objective of the present assay was to study the in vitro potential of some local by-products (i.e. wheat straw, apple pulp and sugar beet pulp) as a co-substrate and ruminant faeces as co-inoculum to optimize CH4 under anaerobic fermentation. The use of referred co-substrates improved significantly biogas and CH4 production although a negative relationship between methane production and slurry dilution was detected (4 and 6% vs. 2% slurry DM, P <0.05).
