Biogas typically refers to gas produced by the anaerobic digestion or fermentation of organic matter, including manure, sewage sludge, biodegradable waste, wastewater, or any other biodegradable feedstock, under anaerobic conditions. Biogas is comprised primarily methane and carbon dioxide.
It is popular for the palm oil industry to capture biogas from palm oil mill effluent (POME). The reasons and benefits of biogas capture are obvious. These include additional revenues from sale of surplus energy and carbon credits. Furthermore, reducing the carbon footprint through biogas capture enables competitive market access of palm products particularly palm biodiesel to environmentally sensitive markets such as the European Union and the United States.
