Anaerobic digestion of mixture of organic fraction of municipal solid waste (OFMSW) with or without pig manure (PM) and digested OFMSW (DOFMSW) by batch reactor with leachate recycling was done at Ho Chi Minh City, Vietnam. The research has carried out in lab- and pilot-scale reactors which have volume of 45 litters and 5 m³, respectively. Maximum biogas production was 378 mL.gVS-1 equal to 59 m³ biogas/ton mixture with wet weight ratio of 10 OFMSW: 1 DOFMSW: 1 PM. Maximum methane content was 63%. The presence of PM in the mixture increased the biogas production while DOFMSW controlled pH and increased methane content in biogas. Pilot-scale gave higher biogas production rate compared to that of lab-scale experiments. The DOFMSW was converted to compost via static pile composting technology within 7 days. The compost yield was in range of 0.2-0.25 ton mixture of waste.
