FGV as sustainable palm oil producer not only looking at sustainability practices & certification in plantation & mills but also looking at reducing emission & carbon footprint at larger scale. FGV understand as POME is detrimental to environment due to methane emission, so building biogas plant in mills reflect commitment to protect surrounding environment. Up to now FGV have already install 25 biogas plant out of 70 palm oil mills.
POME ( Palm Oil Mill Effluent ) produced by palm oil processing needs to be treated by stages of waste water treatment as to comply with Department of Environmental regulations. One of the treatment stage is anaerobic digestion, in which POME high in COD ( chemical oxygen demand ) loading will be reduced to more than 98%. This stage produce biogas from anaerobic bacteria as well as treated waste water for further treatment. Biogas from POME source consist of 55 – 65 % methane, in which usually will be flared off to reduce its GHG emission footprint, as methane is 21 times more detrimental compared to carbon dioxide. Due to technological maturity & availability, biogas can now be utilised to produce electricity via gas engine or biogas compression for industrial customer.
