This project was to investigate the quantity of production and distribution of rice straw and hull in Taiwan, and to conduct field verification of practicable collection, removing, treatment, or reuse methods, in order to carry out cost-benefit analysis and to submit the result to EPA and related agencies for their reference. Besides, this project planned and proposed suitable control measures for the agricultural wastes which have not been regulated as hazardous enterprise wastes and declared to the authorities of their logistics on-line. 1. To investigate the quantity of production and distribution of rice straw and hull, and to conduct field verification of practicable collection, removing, treatment, or reuse methods, in order to carry out cost-benefit analysis and to submit the result to EPA and related agencies for their reference (1) To survey the quantity of production, treatment method, and existing problems of rice straw in Taiwan, in order to analyze practicable treatment technology and control measures (2) To collect quantity data and treatment methods of every city and county in Taiwan in the past 10 years (3) To collect domestic and foreign methods and approaches for rice straw and hull collection, removing, treatment, and reuse, and to compare the similarities and dissimilarities, economic benefits, and advantages and disadvantages of the methods (4) To investigate the existing on-site treatment methods of rice straw and hull in every city and county in Taiwan, and environmental problems emanated from these treatment methods (5) To study methods to have the rice straw and hull treated at sites off the farms, including methods and channels of collection, removing, treatment, and reuse, and to complete the field verification of combining the rice straw for incineration in large-scale urban refuse incineration plant and making the straw into compost. Finally, in conjunction with rice harvest and collection methods, this project assesses the advantages and disadvantages and economic benefits of various methods to provide practicable suggestions 2. To investigate the production and management status of the agricultural wastes which have not been regulated as hazardous enterprise wastes and declared their logistics on-line yet; the investigation result will serve as reference to the EPA for deciding if they should be regulated and declared on-line in the future (1) To survey the kinds, quantities, and management status of the above-mentioned unregulated agricultural wastes, and to plan and propose suitable measures for their control in accordance with current practices of agricultural authorities (2) To hold 3 seminars on agricultural wastes management to discuss the present treatment methods of rice straw and hull, problems and difficulties on declaration, removing, treatment, and reuse of them and other agricultural wastes, and recommend on the countermeasures for their control (3) To hold 1 coordination workshop on agricultural wastes related to this project, to be participated by relevant authorities, environmental protection bureaus in the cities and counties, and personnel from relevant offices of EPA
