Abstract:

Global increase in human population leads to increase in agricultural production, which as well results in rise in the production of agricultural by-products both at farm and industrial levels. Agricultural by-products are renewable energy sources from which essential amount of energy can be recovered, which can be used to replace the use of conventional fossil fuel, reduces the potential of greenhouse gas (GHG) emission and at the same time reduces deforestation, especially in rural areas. Significant attention has been directed towards the reutilization of by-products which result from primary processing of agricultural produce for the production of high value-added products. Heat can be generated from biomass combustion using small and medium scale units. Energy values of biomass from small Agricultural farms, in particular waste generated from different tropical crops, viz; Maize cobs, Millet, Rice and Sorghum husks and Groundnut pods were determined, to ascertain their potentials as alternative fuel sources for rural use. The Energy values of the by-products considered ranged between 11.68 MJ.kg-1 to 17.48 MJ.kg-1 with Groundnut pods and millet husk having the highest and least respectively. With the exception of millet and rice husks whose ash contents and heating values does not meet the given standards, all the by-products can be used as standard feedstock for pellet or briquette production.
