资源是一个国家可持续发展的基础。人类不能无限制地开发自然资源（矿物），而应该尽可能反复利用,逐步建立起资源循环。资源循环学，就是研究如何利用这些产物建立循环系统的科学。资源循环是一个规律，是人类与自然和谐共处、可持续发展的必由之路。资源开发又与环境污染密切相关。尽早建立资源循环型社会，有可能从根本上解决资源短缺和环境污染问题。建立资源循环型社会是一个系统工程，需要政府重视，制定相应法律，科技、教育先行和全社会的共同努力。

Resources are the basis for the sustainable development of a country. From the viewpoint of chemistry, the product, resulted from the usage of a natural resource is still a substance, a kind of resource. Mankind should not exploit natural resources (minerals) unlimitedly, but make full use of them repeatedly and establish resources recycling gradually. Resources recycling is a kind of science that studies how to build the recycling system for making full use of the products. Resources recycling is a law, and also an only road for human being living in harmony with nature and for social sustainable development. Natural resources exploitation is closely related to environment pollution. Socializing resources recycling as early as possible may completely solve the problems of resource shortage and environment pollution. Building a society of resources recycling is a system engineering. To achieve this goal, the Government's determination, the related laws and regulations, keeping science, technology and education going first, as well as the joint effects from the whole society are necessary.
