Abstract [en]

Utilization of renewable energy is an important component of the current sustainable global energy strategy. Currently, biogas is considered one of the most economic and environmentally friendly fuels. Animal waste may serve as an important substrate for biogas production. Pig/swine is the most common domestic animal in many of the European countries, and the swine manure may be a good source of biogas because of its richness in nutrients and energy. This study aimed to determine the production of biogas from the co-digestion of slaughterhouse waste from pigs and pig manure. Slaughterhouse waste from pigs and pig manure were collected from Ginsten slaughterhouse outside Halmstad, Sweden and were then co-digested in lab scale. In the lab, pig manure and slaughterhouse waste were mixed in different ratios (50-50%, 65-35%, 80-20% and 95-5%) to find out the best efficiency. The content of methane (CH4) in the biogas was monitored at four occasions (day 15, 17, 23 and 24). The results show that the methane content was highest in the 95-5% and 80-20% ratios. This study reports that anaerobic co-digestion of slaughterhouse waste from pigs and pig manure could be an important source of renewable energy if the amount of slaughterhouse waste was kept low.
