Greenhouse-gas emission mitigation from the use of agricultural residues: the case of ricehusk

Greenhouse-gas emission mitigation has been estimated for the use of existing and mature biomass technologies. A general methodology has been developed to determine potential amounts of residues that can be made available for energy purposes and the resulting fossil-fuel replacement from utilization of these residues. The consequent reductions in CO2, CH4 and N2O emissions in CO2 equivalents for a time horizon of 20 years, as well as costs of abatements, were calculated. Both traditional and improved energy uses are considered.
