Sumantri Brojonegoro No. 1, Bandar Lampung, Indonesia Country Profile - Indonesia • • • • Area : 1,904,000 km2 Popula*on : 246.9 millions (2012) Growth rate : 5.6 % (2013) GDP per capita : USD 3,420 (2012) (source: h\p://data.worldbank.org/country/indonesia) MALDIVES INDONESIA h\p:// www.geographicguide.net/ globes/pacific-‐islands.htm 3 Palm Oil In Indonesia • Largest Crude Palm Oil (CPO) producer in the world since 2006 • 45.5 % of the world’s CPO are from Indonesia Indonesia Produc*on Indonesia Exports Source: h\p://ers.usda.gov/ Mass Balances for 40 ton FFB/hour 9.7 ton/hr FFB WATER Diesel oil 0.075 kL/hr 40 ton/hr 9.4 ton/hr 1.7 ton/hr 60 ton/hr 720 kWh/hr Electricity FUEL PALM OIL MILL 9.4 1.7ton/hr ton/hr 4.8 ton/hr 2.8 ton/hr Steam 24 ton/hr 24 ton/hr Palm oil EFB Kernel WASTE Kernel EFB Fiber 85% 55% Shell POME 5.6 ton/hr FFB – Fresh Fruit Bunches; POME – Palm Oil Mill Effluents; EFB – Empty Fruit Bunches Waste from Palm Oil Ac9vi9es Plantation FFB POM Oil palm trunk Oil palm frond EFB Waste POME root Palm kernel shell Biomass waste FFB-Fresh Fruit Bunches POM – Palm Oil Mill EFB – Empty Fruit Bunches Current Prac9ces in Indonesia POM BIOMASS UTILIZATION IN PALM OIL MILL FFB Open Anaerobic Ponds The anaerobic ponds emit a huge amount of the strong greenhouse gas, i.e. methane and the effluent of the ponds contains nutrients responsible for pollu*on of surface and ground water Land Applica9on for Palm Oil Mill Effluents • POME, either in fresh or treated form, contains a high level of plant nutrient. When the BOD level is brought down to below 5,000 mg/l, the treated POME is allowed to u9lize for land applica9on in oil palm planta9ons. Studies by various groups have demonstrated that such an applica*on has been beneficial to oil palm, besides the saving on fer*lizer cost extensively. • However, controlling the ground and surface water pollu9on is the key factor for successful of the land applica*on. SUSTAINABLE WASTE MANAGEMENT Possible Options EFB à incineration àmulch or fertilizer Biogas from POME à existing energy system or for electricity generation EFB à co-composting with POME Dewatered EFB à heat and/or electricity or organic diesel The recovered remnant oil à supplement for CPO production or used to produce bio-diesel Palm Plantation Crude Palm Fresh Fruit Oil Bunches Extraction Empty Oil Palm Oil Palm Root Fruit Frond Trunk Bunches Crude Palm Oil Excess Remnant Palm Kernel Oil from Shells EFB Refining Process Liquid Waste Palm Oil Mill Effluent Electricity Genera9on from POME The benefit of methane capture from POME and their impact to reduce global and local environmental burden The poten9al of electricity produc9on and CO2e emission reduc9on from POME at palm oil mill with capacity 45 tons of FFB/hour Integrated Solu9on for zero-‐waste effluent and palm oil solid waste Remarks: 1.

With the process of mulch or compost produc*on from EFB in combina*on of POME, with or without biogas produc*on before, it is possible to realize a sustainable process in palm oil mills with zero waste. • In palm industries cluster, significant amount of biomass waste generated and disposed leading to environment and local health issue. Introduc*on of new technologies, cluster management system, market orienta*on are essen*al for a successful transforma*on of these biomass waste West Hall INSTITUT TEKNOLOGI BANDUNG
