Using Agricultural Residues as a Biomass Briquetting: An Alternative Source of Energy

Every year millions of tons of agricultural wastes are generated which are either destroyed or burnt inefficiently in loose form causing air pollution.These wastes can be recycled & can provide a renewable source of energy by converting biomass waste into high density -fuel briquettes without addition of any binder.This recycled fuel is beneficial for the environment as it conserves natural resources.For this the biomass briquetting is the main renewable energy resource.In this paper the raw material including rice husk, coffee husk, saw dust, ground nutshell and cotton stalks etc. were densified into briquettes at high temperature and pressure using different technologies.We discuss the various advantages, factors that affecting the biomass briquetting and comparison between coal and biomass briquetting.The details of the study were highlighted in this paper.
