Palm Oil Mill Effluent (POME) is considered a problematic waste, causing pollution problems: greenhouse gas emissions, water pollution with organic material, and nutrient pollution. POME is well suited for treatment in digestion tanks, generating methane for energy production. A technology screening showed membrane technology as the most promising technology for further processing of POME digestate into a mineral concentrate and high quality water. However, a techno-economic evaluation showed that the estimated costs related to further processing of POME digestate are currently higher than the potential savings. Options for cost reduction of the membrane technology and of the handling of the mineral concentrate should be explored. In an optimistic scenario the potential savings exceed the costs. If the concept is further developed, processing of POME digestate can contribute to the economic viability of digestion systems and to reducing the environmental impact of palm oil mills.
