Abstract

Widely recognized as a potential feedstock for generating biomethane, palm oil mill effluent (POME) availability may become limited. This condition will require alternative feedstocks. Anaerobic codigestion (ACoD) has been studied for optimizing POME processing. A significant advantage of ACoD is the optimal C:N ratio achieved by combining substrates without any pretreatment. Several studies on ACoD of POME and other palm oil wastes have been conducted. Co-digesting POME and decanter cake (DC) at 55&#8451- without any further additives for optimizing the C:N ratio resulted in a methane yield of 408.88 mL CH4/g VS. This paper will discuss the advantages of ACoD of POME and other wastes and suggest ACoD implementation in accordance with the future commitments of the palm oil industry.
