Oil Palm Empty Fruit Bunch (OPEFB): Unlocking the Value of a Versatile Agricultural Byproduct
As a major byproduct of the palm oil industry, Oil Palm Empty Fruit Bunch (OPEFB) was once regarded as a cumbersome waste, with millions of tons generated annually worldwide. Composed of lignocellulosic biomass—cellulose, hemicellulose, and lignin—along with essential nutrients, OPEFB has evolved from an environmental burden to a high-value resource. Its diverse applications span bioenergy, chemical synthesis, agriculture, and environmental remediation, embodying the principles of circular economy and sustainable development in the palm oil industry. Bioenergy production stands as one of the most mature and widely adopted uses of OPEFB. After briquetting to enhance fuel properties like moisture content and heating value, OPEFB can be gasified in fluidized bed gasifiers to produce bio-syngas, a mixture of hydrogen, carbon monoxide, and methane with a heating value of 4-8 MJ/Nm³. This bio-syngas serves as a clean alternative to fossil fuels for power generation and heating. Additionally, OPEFB gasification concurrently yields high-quality biochar, which further expands its energy and agricultural utility, creating a dual-output energy solution.
