EcoDesign of Multilateral Recycling Systems in Asia

国家之间经济条件的差异在未来不会消失。只要差距存在，废弃产品、零部件和材料将继续流向亚洲国家。维护合法的国内回收系统当然是必不可少的。因此，我们必须认识到有许多产品从合法系统中泄漏出来。但泄漏产品的实际情况尚未查明。为了实现亚洲多边回收系统的生态设计，有必要澄清这些泄漏产品的状况。我们尝试使用回收利润分析模型来识别条件。这些结果表明，在亚洲地区使用的材料回收产生更多的利润，从几百到几千日元每件产品，比日本。关于产品及其零部件的再利用，海运成本对二手业务及其战略有很大影响。今后，有必要 ...更多信息 重建回收策略，包括泄漏产品的问题。这就是以合法的国内回收系统为基础的多种形式的系统，以及弥补这些缺陷的多边系统。我们还以个人电脑为例，构建了亚洲全球循环的模型，并评估了各种方案的环境意识和盈利能力。为此，我们采用了生命周期模拟的思想，模拟产品生命周期的各种流程，并将在这种全球循环中不可避免地发生的风险纳入模型。模拟结果表明，产品和零部件的再利用可能上级当地的循环在环境意识和盈利能力，而只有材料回收的循环是不是。这种与大量材料出口回收的实际情况的不匹配表明了两种见解：（1）该模型没有包括可能导致成本增加的不适当处理;（2）实际情况没有适当考虑风险。为了在亚洲构建可持续的全球循环，研究阐明了可追溯性管理是最大的问题之一，可追溯性管理可以通过使用风险模型来建模。

The disparity in economic conditions between countries will not be lost in the future. As far as the disparity exists, the flow of the discarded products, parts, and materials to Asian countries will continue. The maintenance of lawful domestic recycling systems is certainly essential. And so, we have to recognize there are many products leaking out of lawful systems. However, the actual condition of leaked products has not been identified. For achieving ecodesign of multilateral recycling systems in Asia, it is necessary to clarify the condition of these leaked products. We tried to identify the condition using the recycling profit analysis model. These results show that material recycling utilized in Asian areas produce more profits from several hundreds to thousands of yen per product, than that of Japan. Regarding the reuse of the products and their parts, marine transportation costs have a large effect on the secondhand business and its strategies. In future, it will be necessary … More to reconstruct recycling strategies including the issue of leaked products. That is the multiform system based on lawful domestic recycling systems, and multilateral ones that compensate for these faults.We also construct models of the global circulation in Asia by taking a personal computer as an example and evaluates environmental consciousness and profitability of various scenarios. For this purpose, we employed the idea of life cycle simulation that simulates various flows of a product life cycle and incorporate the risks that inevitably occur in such a global circulation into the model. The simulation results revealed that reuse of products and components may be superior to the local circulation in terms of both of environmental consciousness and profitability, while the circulation only with material recycling is not. This mismatch with the actual situation, where a lot of materials are exported for recycling, suggests two insights : (1) the model does not include inappropriate processing, which may result in higher costs and (2) the actual situation does not appropriately consider risks. In order to construct the sustainable global circulation in Asia, the study clarified that traceability management is one of the largest problems and the traceability management can be modeled by using the risks Less
