Chumporn Palm Oil Industry Public Company (CPI) is a major manufacturer of palm oil in Thailand, while its sister company CPP focuses on palm oil refinery and energy production. To reduce material wastage and fossil fuels consumption, CPP generates energy from biomass and biogas. While fuels from palm processing were readily available, the company used an anaerobic wastewater management system to produce supplementing biogas, which does not only reduce CO2 emission but it also decreases methane emission, resulting in an economical, efficient and eco-friendlier system. The key to BIB’s success in this project was the ability to handle both biomass and biogas fuels. EFB is especially difficult to burn due to its high moisture content, low ash melting point and low heating value. The boiler was specifically designed to match these fuels, at the same time enabled high efficiency to be achieved. The steam produced in turn was used in the refinery process while the excess electricity was sold.
