Product Recycling Systems

拟议的工作旨在通过建模回收系统性能并将其与产品设计联系起来，帮助社会走向可持续的材料使用。 该模型将考虑拆卸、价值获取、危险材料处置和材料回收。 绩效将从成本、能源和环境影响方面进行评估。这一建模工作的一个中心特征将是捕获单元过程和系统在输出纯度和废物方面的性能。 产品信息将从设计师团队，公共文档和产品拆卸分析中获得，这些分析将由学生在环境友好制造课程中进行。 数据和再循环设备参数将从现有的操作和分析模型中获得。这个项目的合作者有：惠普公司，包括他们与诺兰达的联合回收企业，国家电子制造倡议，RRT设计建设，并行技术公司，福特和查帕拉尔钢铁公司。 此外，麻省理工学院的斯坦利·格什温博士将帮助我们进行系统建模和设计。这项工作最初将侧重于电子产品的回收步骤，并将为设计人员提供回收工具。将特别关注日本、欧洲和美国的回收立法。这项工作的贡献将是挑战当前的设计思维，教育未来的工程师在设计的后果，建立回收系统模型，并开发一种方法来评估产品的设计回收。这项工作还将通过以下方式对社会产生重大的教育影响：1）研究生和本科生直接参与本项目的产品分析部分，2）通过会议和期刊论文传播我们的工作。

The proposed work is intended to help society move toward sustainable materials usage by modeling recycling system performance and relating it to product design. The model will account for disassembly, value capture, hazardous materials disposal and materials reclamation. Performance will be evaluated in terms of cost, energy and environmental impact. A central feature of this modeling effort will be to capture the performance of unit processes and the system in terms of output purity and wastes. Product information will be obtained from a team of designers, public documentation, and product tear down analysis to be conducted by students in courses on Environmentally Benign Manufacturing. Data and recycling equipment parameters will be obtained from existing operations and analytical models. Collaborators on this project are: Hewlett-Packard, including their joint recycling venture with Noranda, the National Electronics Manufacturing Initiative, RRT Design & Construction, Concurrent Technologies Corporation, Ford, and Chaparral Steel. In addition, Dr. Stanley Gershwin of M.I.T. will assist us in system modeling and design. This work will focus initially on the reclamation steps for electronics products, and will lead to design for recycling tools for designers. Specific attention will be given to takeback legislation in Japan, Europe, and the United States. The contributions of this work will be to challenge current design thinking, educate the future engineers in design consequences, build recycling system models, and to develop a methodology to evaluate product designs for recycling. This work will also result in significant education impacts to society through: 1) direct involvement of both graduate and undergraduate student in the product analysis part of this project, and 2) dissemination of our work through conference and journal papers.
