Design and Fabrication of Biomass Pelleting Machine

Abstract

Many developing countries produce huge amount of agro waste. The disposal of this waste is a major problem. The residues like wheat and rice husk, sawdust from carpentry shops, groundnut shells, and dry leaves from plants are available in a large quantity. Apart from the problems of storage, transportation and easy handling of this waste, burning of biomass in grates poses a greater problem of widespread air pollution. Also, the conversion efficiencies are poor. There is a rising issue of depletion of conventional forms of energy. Energy is a key factor in the development of any country. But due to large scale exploitation of fossil fuels like coal, petrol, diesel, etc. there is a possibility of these fossil fuels fading away. According to the reports, there has been an increase in the use of fossil fuels by 0.6%, which amounts to around 127 million metric tons of consumption. So, renewable energy resources are becoming pertinent by hour. Another global issue faced is waste management. Initiatives to recycle and reuse have recently started. They have provided a right step forward. But recycling of waste in the same form has practical limitations. In the view of above problems, we propose to fabricate a machine which will convert the waste biomass (agro-waste) into a reusable form of briquettes which will be easy to handle, transport and store.
