PALM OIL MILL EFFLUENT RECYCLING SYSTEM FOR SUSTAINABLE PALM OIL INDUSTRIES

Udin Hasanudin, Agus Haryanto

Abstract


Having sustainable is a key issue in the development of palm oil industries in Indonesia. Palm oil mill effluent (POME) is a largest waste from palm oil mill with very high concentration of organic matter. Several methods have been developed to treat the POME but it is rather difficult to fulfil the national effluent standard. The objective of this research is to evaluate the environmental impact of some currently implemented methods of POME treatment, such as: (1) open lagoon and land application of treated POME (as a base line), (2) methane capture and land application of treated POME, and (3) co-composting of empty fruit bunches (EFB) and POME. Green House Gases (GHG) emission reduction and renewable energy production were evaluated. Results showed that compared to open lagoon system, methane capture followed by land application of treated POME was estimated to successfully produce renewable energy about 55,3 kWh/ton of fresh fruit bunches (FFB) and GHG emission reduction about 241.2 kgCO2e/ton FFB. Utilization of treated POME as liquid fertilizer improved soil quality and increased FFB production by about 13%. Co-composting of EFB and POME was estimated to successfully reduce GHG emission about 115.9 kgCO2e/ton FFB and 191.9 kgCO2e/ton FFB for 30 and 70 days composting periods, respectively. Compost application also improved soil quality and increased FFP production about 5-10%.
