Briquettes produced from waste materials present a sustainable energy alternative that can mitigate environmental impacts, forest degradation, and deforestation. The compaction of biomass residues, termed briquetting, transforms this waste into an efficient and viable clean energy source suitable for rural and suburban communities. The primary objective of this research was to design, fabricate and testing of a tapered screw-type briquetting machine for briquette. The machine was designed and fabricated using mild steel, and was tested for production, the machine was powered by a 1 hp (746 W) single-phase electric motor integrated with a gearbox. Key parameters were a hopper capacity of 151.68kg, a 450 mm screw length, a 400 mm extrusion barrel, a 39 mm extruder diameter, and a 700 mm drive belt. The efficiency of the machine and throughput capacity were computed to be 89% and 135 kg/h while the material has a maximum density of 840 kg/m³ and relax density of 326.17 kg/m³. This development proved effective in converting common agricultural residues such as rice husk, sawdust, and sugarcane peels into dense, combustible briquettes suitable for both domestic and industrial heating applications.
