2. Sustainable livelihood in the rural and urban areas must mean a change in the energy use. The use of fuelwood and charcoal must be reduced to the lowest minimum through energy substitution. In many African countries, there are several rural areas that have been electrified. Unfortunately, to a large extent, it is being used for lighting not as energy for household consumption and production purposes. Some rough calculations have shown that it costs slightly less per household to use gas rather than charcoal that the urban households prefer to use.

They are unable to make the substitution because of initial high fixed cost of buying gas stoves. Through community partnerships, poor people must be assisted to form associations for rural credit mobilization (such as the Susu system in Ghana) to enable them purchase gas and electric stoves. Innovative hire-purchase (credit) system should be introduced to enable urban and rural households purchase these stoves. In cases where the cost of electricity or gas is the constraint, subsidies that are equal to the cost of deforestation should be put on them to enable as many people do the energy switch.

Given that the cost of 1 t of straw including transportation is about $20; such a project can be economically viable. 9 Conclusions An industrial process has been developed to produce three valuable products from a waste material, namely from rice straw. A reduced-scale simulation for various components of this process has been conducted. The core of the process is an advanced combustion technology produced in Canada. The three products resulting from this process are: rice straw ash (RSA), significant amount of energy and a liquid fertilizer.
