Biomass Residue and Renewable Energy, Resource Efficiency at Palm Oil Mills
Apart from palm oil, biomass residue and the renewable energy derived therefrom are among two important products, sometimes overlooked, of palm oil mills in the oil palm industry. It is imperative that palm oil mills are recognised in the context of national resource efficiency for efficient utilisation of these products in order to maximise their contribution to the industry and national economy.
Despite the energy-efficient cogeneration technology currently employed at palm oil mills, most of the prime biomass residues at palm oil mills is presently consumed merely to provide heat and power to its processes. A truly energy-efficient design of a palm oil mill incorporating readily available innovative technologies can reduce its biomass residue consumption to less than half of the present consumption. The biomass thusly saved could be utilised elsewhere for useful purposes. In addition to large quantities of surplus prime biomass conserved at the mill for export, surplus electricity can be more efficiently generated within the mill for export to the grid, where grid access is available.
