Bioenergy and Biomass Asia Strategy

摘要

In general, biomass refers to a substantial number of bioorigin resources that can be utilized as a source of energy and raw materials. Wood, grass, marine algae, micro algae, agricultural wastes, forestry wastes, and municipal wastes fall into this category. Energy crops form one part of the promising biomass that may make energy plantation possible on a large scale, though this has not yet been commercialized at the present. How does biomass differ from other renewable energy sources? Biomass forms its own body by photosynthesis utilizing solar energy. If biomass is burnt finally and carbon dioxide is emitted to the atmosphere, the net concentration of carbon dioxide in the atmosphere remains unchanged as far as the carbon dioxide can be photochemically fixed into biomass.
