Society’s dependence on fossil fuel for mass production, mass consumption, and mass disposal has caused serious environmental problems such as global warming, pollution, wastes and toxic substances. In this context, the value of effective use of biomass, a renewable, biologically derived organic resource, is receiving considerable attention. Many of the countries of Asia are rich in biomass resources due to their climate and other factors.

The Chinese government has recently made tremendous efforts to accelerate rural energy development. The rural energy policy aims at minimizing commercial fuel use by focusing on efficiency improvement and developing renewable energy technology. Under this policy, biomass energy the main energy source in rural areas, has been given top priority.
