Nepal still relies heavily on fuelwood for its enegy requirement. Near about 90% of the enelgy is met by traditional biomass-fuelwood, animal dung and agricultural residue. Different biomass raw materials (forest and agrowastes) were studied for the purpose of briquetting. Besides producing diferent extruded biomass briquettes (EBB) based on rice husk, addition of coal to these briquettes to get extruded biomass mineral briquettes (EBM), biobriquettes based on different biomass and coal were produced with different proportions of biomass to obtain acomposite fuel called biocoal (BC). Combustion tests for domestic as well as industrial applications were attempted. Results of the laboratory tests and field tests of these products show that they have better combustion characteristics than traditional fuels. In household cooking as well as other purposes they gave better results than most of the commonly used fuels. They can very well be used as a substitute for the traditional fuels in domestic as well as industrial applications in furaces, boilers and kilns.
