Palm oil industry generates vast amount of palm biomass. Converting palm biomass into a uniform and solid fuel through briquetting process appears to be an attractive solution in upgrading its properties and add value. In this study, raw materials including empty fruit bunch (EFB), in powder and fibre forms, palm kernel expeller (PKE) and sawdust were densified into briquettes at high temperature and pressure using screw extrusion technology. The briquettes were analysed to determine its physical and chemical properties, mechanical strength and burning characteristics. It was found that briquettes made either from 100% pulverized EFB or mixed with sawdust exhibited good burning properties. EFB fibre and PKE, due to their physical properties, were recommended to be blended with sawdust in producing quality briquettes. In overall, converting palm biomass into briquettes has increased its energy content and reduced moisture content about minimum of 5% and 38% respectively compared to its raw materials. The properties of palm biomass briquettes obtained from the study were compared to the commercial sawdust briquettes properties and to the minimum requirements of DIN 51731. The details of the study were highlighted in this paper. Palm biomass briquettes can become an important renewable energy fuel source in the future.
