Biomass is one kind of renewable energy sources.Commercial technologies for renewable energy from crops are well developed and known as the process of the first generation. The processes of second generation aredeveloped by using lignocellulose-containing raw material which is easily obtainedand cheap.Lignocellulose-containg biomass is an important raw material for the development of biomass energy in the future. Agricultural wastes–such as straw, rice husk, bagasse etc., were burned or thrown away in the past. Taiwan's annual output is about 4 million tons. But if they could be converted by using technology, we can not only resolve the problem of waste pollution, and reduce greenhouse gas emissions, but also improve the comprehensive benefits of agriculture. Technologies of agricultural waste conversion into renewable energy include thermochemical (gasification, pyrolysis), biochemical (microbial fermentation, microbial conversion), and physical chemistry ( alcoholization, esterification ). The study analyzed the development of biomass energy conversion technology by collecting biomass energy technology research in order to find out the suitable technology to process agricultural waste. Without sufficient indigenous energy sources in Taiwan, in order to increase the proportion of energy independence, we should consider foreign experiences, make related policies, regulations, and offer facilities to promote the use of renewable energy of agricultural waste.
