Conclusions

Advancement of economy and technology makes current uses of rice straw uneconomical, and they will eventually be terminated. Thus, disposal of this vast amount of straw will be a serious problem in areas where rice is the major agricultural product. Many ideas have been developed to use straw — for pulp and paper, construction materials, soil incorporation, compost, fuel, etc. However, because of other competitive resources, the prospect of immediate use of straw for these purposes is dim. Some potential is seen in using straw as an animal feed. Rice straw, however, is a poor-quality feed in its natural state. It must be pretreated (to increase digestibility) or supplemented by other ingredients before it can be considered a suitable animal feed. Several new processes have been developed to attain these objectives by microbial action. Most of these new processes are in the laboratory-bench or pilot-plant stage, so that at the present time, the economic feasibility of these processes is not certain.
