The majority of municipal wastewater treatment plants in Sweden produce biogas from sewage sludge. In order to increase methane production, different scenarios for redirecting organic fraction of municipal solid waste (OFMSW), collected at municipalities, into usual biogas production lines were explored. Both co-digestion of sludge and OFMSW, and mono-digestion of OFMSW with addition of a trace element mixture were examined. The study showed that the option of co-digestion results in higher methane yields, due to synergetic effects. Mixing OFMSW, with a high protein content, and sludge, which has higher trace element content, leads to improved C/N-ratio and nutrient supply. View this paper.
