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，根据经济增长和城市化，市政固体废物和工业固体废物正在迅速增加。尽管估计未来的废物产生并考虑废物管理策略很重要，但未准确衡量废物的量，或者在某些亚洲国家未向公众披露此类信息。在这项研究中，我们开发了两种固体废物产生的估计模型，可以通过使用有限的有关家庭消费和行业统计信息来识别它们。目标国家是台湾，中国，韩国和日本。第一个估计模型可以通过使用基于消费者的行为理论的家庭消费的信息来预测产生/发射的市政固体废物（MSW）的数量。估计它们的废物产生。通过结合经济模型，可以将未来的社会经济状况与废物产生模型相结合，可以估算未来的废物产生。 MSW对台湾发射的短期预测是根据国家环境计划和社会经济变量的假定方案进行的。在分析结果时，讨论了更可持续的消费模式，可以计划相应的MSW管理系统，以发展低废物排放社会。第二个估计模型的重点是实质材料的流动。提出了一种使用有限数量的废物数据，各种工业统计数据以及可回收材料的输入和输出平衡来估算废物产生和回收未知数的方法。该方法适用于估计不仅亚洲国家的废物产生和回收利用，而且还对世界上其他国家群体进行了估计，并对结果进行了分析和讨论。
