| Abstract | An attempt has been made to estimate the potential of greenhouse gas emission
mitigation by different existing and mature biomass technology options. A general
methodology to be used for this purpose has also been developed. It provides for the
estimation of the potential amount of residues that can be made available for energy purposes
and the potential of fossil fuel replacement by the utilization of these residues in the selected
options of biomass exploitation. The consequent potential for carbon emission mitigation as
well as the added costs of such abatement were then estimated.
Three different biomass residues, namely rice husk, wood residues and biogas from
animal wastes were studied to determine the net carbon emission that can be avoided by
extracting their energy. The methodology has been fully demonstrated in the case of rice
husk by estimating the mitigation potential considering the use of the amounts wasted at
present as well as the amounts that can potentially be saved by improving the efficiency of
current energy practices. However in case of woodwastes and biogas, lack of sufficient
information lead to a simplified approach of determining the net carbon emission mitigation
potentials by considering the entire amount of residues (including the amounts already used
as fuel) that may be potentially available for energy uses.
Wood residues were found to provide the highest energy potential among the three
residues analyzed (followed by biogas) and offered the highest total carbon mitigation
potential as well. But rice husk proved to be offering a better economy than the other two
sources, mostly because of the sales value of the ash generated which may be used in cement
making, steel-lading or in chemical industries for toxic waste clean-up. |
