废旧机电产品资源化

针对经济快速发展、人们消费水平提高、产品更新换代频率加快与自然资源日益匮乏的矛盾，研究了废旧机电产品资源化的必要性、可行性及重大意义。指出废旧机电产品资源化的基本途径是减量化、再利用、再制造和再循环，废旧机电产品资源化的目标是使再利用、再制造的部分最大化，使再循环的部分最小化，使安全处理的部分趋零化。再制造产业快速健康的发展，可以创造出可观的经济效益，可以提供大量就业岗位，并对节约资源、节省能源、保护环境做出重大贡献，从而有力地支持社会可持续发展。工程师在推进再制造事业发展中的使命包括：在产品设计的源头考虑产品末端资源化的策略；在产品运行阶段不断吸纳降低能耗、延长寿命的新技术；在产品报废阶段，充分利用再制造技术，使资源利用率最大化、环境污染最小化。

Resource Recovery of Waste Machinery and Electronic Products

Considering the contradiction between the rapid developmental economy, the enhancement of people's consumption level, the quickening of product updating frequency and the shortage of natural resources, this paper investigates the necessity, feasibility and significance of resource recovery of waste machinery and electronic products (WMEPs), indicates that the basic approaches of resource recovery of WMEPs involve reduce, reuse, remanufacturing and recycling ("4R"), aiming at maximizing the part of reuse and remanufacturing and minimizing the part of recycling. Fast and healthy development of remanufacturing industry can create considerable economic benefits, offer plentiful employment opportunities, and help to save resource, energy and protect environment, which facilitates the sustainable development of our society. The responsibilities of engineers in driving the resource recovery of WMEPs includes incorporating the strategy of resource recovery of end-of-life product in the origin of product design; adopting new technologies for extending the life of products and reducing energy consumption in the use stage of product; using remanufacturing technologies fully in order to maximize the using efficiency of resource and minimize the environment pollution.
