Study on Slaughterhouse Wastes Potency and Characteristic for Biogas Production
Budiyono, I N.Widiasa, S.Johari, Sunarso
The objective of study was to indentify of the sources and characteristic of slaughterhouse waste for biogas production. The identification waste was done by observing the slaughtering activities on slaughterhouse owned by Regional Government of Semarang City. The wastes studied include the rumen, wastewater, and manure and the characteristics include physical and chemical. Based on the slaughterhouse waste characteristic, either liquid or solid, slaughterhouse waste was very suitable and has high potential to be treated anaerobically for biogas production. The wastewater has the potency for producing total biogas as 2.472 m3/m3 of wastewater. The degradation of cattle manure has the potency for producing total biogas of 618,90 L/kg in dry based by the composition of CH4, CO2, NH3 were 48.89, 47.87, and 2.43 % volume, respectively. In other terms, cattle manure will produce CH4 as 305.06 L/kg in dry based.
