项目摘要

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.

在亚洲国家，随着经济增长和城市化进程的加快，城市固体废物和工业固体废物的数量也在迅速增加。虽然估计未来的废物产生量和考虑废物管理战略很重要，但在一些亚洲国家，废物产生量没有得到准确的计量，或者没有向公众披露这些信息。在本研究中，我们开发了两种固体废物产生量的估算模型，可以通过使用有限的家庭消费和工业统计数据来确定。目标国家是中国台湾、中国大陆、韩国和日本。第一个估计模型可以预测产生/排放的城市固体废物（MSW）的量，通过使用基于消费者行为理论的家庭消费支出的信息。估计其废物产生量。通过将可预测未来社会经济状况的经济模型与废物产生模型相结合，可估计未来的废物产生量。本研究以国家环境规划及社会经济变数假设方案为基础，对台湾都市固体废弃物排放量进行短期预测。通过对结果的分析，探讨了一种更可持续的消费模式，并规划了相应的城市生活垃圾管理系统，以实现低排放社会的发展。第二个估算模型侧重于大量材料的流动。提出了一种利用有限数量的废物报告数据、各种工业统计数据和指定可回收材料的投入产出平衡来估计废物产生和回收的未知量的方法。应用该方法对亚洲国家和世界其他国家的废物产生和回收进行了估算，并对结果进行了分析和讨论。
