目前,我国矿山机械产品的回收利用率低、再制造技术使用率低,因而导致资源的大量浪费和环境的严重污染。为了缓解有限资源和无限浪费之间的矛盾,减少环境污染,我国政府做出了“发展循环经济、建设节约型社会”的重大战略决策。循环经济中的4R原则(Reduce减量化、Reuse再利用、Recycle再循环、Remanufacture再制造)就是最大限度地减少资源消耗,同时又把废弃物最大限度地变废为宝,减少自然资源的消 At present, the recovery rate of mine mechanical products in our country is low, and the utilization rate of remanufacturing technology is low, resulting in a lot of waste of resources and serious environmental pollution. In order to alleviate the contradiction between limited resources and unlimited waste and reduce environmental pollution, our government has made major strategic decisions such as “developing a recycling economy and building a conservation-oriented society.” The 4R principles of circular economy (Reduce reduction, Reuse reuse, Recycle recycling, Remanufacture remanufacturing) is to minimize resource consumption, while turning the waste into treasure, reducing the consumption of natural resources
