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 àmulch 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

Conclusions •  The benefits of POME u*liza*on for biogas produc*on and compos*ng are the renewable energy produc*on, saved POME treatment cost in pond systems, total u*liza*on of the POME nutrients, reduced cost for EFB transport and u*liza*on, and higher FFB yields in the planta*on. 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
