The demand for energy is increasing constantly with the increasing population of the world, and the major source of energy (oil and gas) is limited. Fossil fuels are the major source for energy. The excess use of these fuels will lead to serious environmental issues like global warming and air pollution. Since the fossil fuels are getting depleted day by day, it is the high time to convert biomass wastes such as sawdust, rice husk etc., to useful biomass briquettes which will be the substitute for some of the fossil fuels. This, calls for sustainable energy production and supply such as renewable energy technologies. | Development of manually operated piston press type briquetting machine
