| Research Abstract |
In Asian country, municipal solid waste and industrial solid waste are increasing rapidly according to economic growth and urbanization. Although it is important to estimate future waste generation and to consider strategy of waste management, the amount of waste generation is not measured accurately or such information is not disclosed to the public in some Asian countries. In this study, we developed two kinds of estimation model of solid waste generation, which can be identified by using limited available information on household consumption and industry statistics. Target countries are Taiwan, China, Korea and Japan. The first estimation model can project the amount of generated/emitted municipal solid waste (MSW) by using information on expenditure of household consumption based on consumer's behavior theory. their waste generation are estimated. Via coupling the economic model, that can project future socio-economic situation, with the waste generation model, future waste generation can be estimated. A short-term projection of MSW emission of Taiwan is conducted on the basis of the national environmental plan and the assumed scenarios for the socioeconomic variables. In analysis of the results, a more sustainable consumption pattern is discussed, and the corresponding MSW management system can be planned, so as to develop a low waste emission society. The second estimation model focuses on the flow of substantial material. A method to estimate the unknown quantity of waste generation and recycling using a limited number of reported waste data, various industrial statistic, and the input and output balance of the specified material of recyclable is proposed. This method is applied to estimate the waste generation and recycling of not only Asian countries but also other country groups in the world, and the results are analyzed and discussed.
