Converting Waste Agricultural Biomass into a Resource - UNEP

The technology of rice husk gasifier could be effectively used in households
which were agreed with the spread of husks that were all over the places. In
Lao, the economic value of rice husk gasifier is compared to that of LPG
stove. The study of the economic value is done based on 5 year lifetime of
the gasifier. The cost of 15 kg LPG is 350 Baht. The fuel consumed per year
of the gasifier is equivalent to 6 units of 15 kg LPG. As the cost of gasifier is
5,000 Baht per unit, the savings on LPG is 3,600 Baht per year, resulting in
1.4 years of payback period and 61.95% IRR.
Advantages to Developing Countries 70
According to a recent study, the total potential of saving biomass used for
domestic cooking through substitution of the traditional stoves by improved
ones in six Asian countries (China, India, Nepal, Pakistan, Philippines and Sri
Lanka) is about 277 million tons/year (Bhattacharya et. al, 1999); the saving
amounts to about 36% of the biomass consumption for cooking in these
countries at present.
