Every year millions of tons of agricultural wastes and forest residues are generated. These are either wasted or burnt inefficiently in their loose form causing air pollution. Handing and transportation of these materials is difficult due to their low bulk density. These wastes can provide renewable source of energy by converting in to high density fuel briquettes with out addition of any binder Briquettes have high specific density (1200kg/m3) and bulk density( 800kg/m3) compared to 60 to 180 kg/m3 of loose bio mass. These can stand the ardors of long distance transport. Loading/ unloading and transportation cost are much less and storage requirements is drastically reduced. Compared to firewood or loose bio- mass, briquettes give much higher boiler efficiency because of low moisture and density
