"Biomass Japan Strategy Policy" anticipates quantity of annual waste biomass as 68 million ton (dry weight) in Japan, and aims for effective utilization of 80% of them. A reliable quantity of waste biomass in the world is not shown till now. Agricultural residues are estimated as 4.5 billion ton in Asia, because agriculture is the base sector in developing countries in Asia (about 10 billion ton in the World). Some part of such wastes (around 30-40%) are utilized as fuel, feedstuff, fertilizer, paper making and so on, but huge amount of them are still left without utilization. The physical and chemical properties of these residues are quite diverse, the effective utilization of these residues should be developed with consideration of such properties (right materials). In addition, the consideration of the harvesting season and transportation of them (the right position) is also important for the effective utilization. It would be essential to establish systematic industrial complex for the effective utilization of biomass ("biomass industrial complex") from the preservation of regional and global environment and production cost efficiency of view. Some designs of such system in Southeast Asia as a target are discussed.
