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.
