CURRENT WASTE MANAGEMENT (case: palm oil mill) • SOLID handling - Empty Fruit Bunch current incineration or mulching (no EFB treatment) disadvantages : - loss of oil in the EFB - unutilized potentially renewable energy source - Empty fruit bunch current utilization for boiler disadvantage : - EFB contains high moisture (lower calorific value)

• LIQUID treatment - Palm Oil Mill Effluent (POME) or effluent from tapioca industry current open lagoons digestion disadvantages : - methane emission to atmosphere (global warming gas) - loss of potentially renewable energy source - large area required for ponds

Biogas Project in Indonesia • Domestic utilization: Currently there is more than 13,500 unit of biogas digester are installed to meet domestic needs (cooking and lighting). Biogas is produced from animal manure; • Commercial/industry sector: Biogas program is implemented through the commercial basis. The biogas unit system is built in a large scale, usually to generate an electricity. Biogas is produced from palm oil mill effluent (POME), tapioca effluent and municipal solid waste.
