Agricultural Residues for Energy Production
Based on the national scale mapping done in
the pilot phase, residues from rice and cotton were considered the
most promising residues for energy production in Mali.
For agricultural residues there is a large
difference between the theoretical amount and the amount available in practice, mainly because most agricultural residues
are currently used for multiple purposes, and hence have a value.
Spatial maps of the theoretical amounts of
residue for rice and cotton have been produced on the basis of national
statistics, and practically realistic amounts of rice straw for
energy use from Office de Niger, have been estimated on the basis
of detailed field studies, comprising 400 questionnaires. An
environmental analysis of the impact of using rice straw as a
fuel instead of mulching was conducted on the basis of a literature review and
collected soil samples.
The assessment is available in:
Given a considerable amount of rice straw
available for energy purposes, a pre-feasibility study of a rice
straw fired power plant of 3-5 MWel was conducted. The
study comprises conception of systems for collection, transport
and storage of straw and the conception of the straw fired power
plant. The feasibility study, providing estimates of
investment as well as operation and management cost for the entire
system from field to grid, is available in:
