Broad recycling use of regeneration resourcesStarting from in the 1950 of the 20th century, China set up a nationwide recycling system, the early 50 's, the Central Committee decided to establish the Department of heavy industry metal recovery, the country of supply and marketing cooperatives set up waste recycling, initially formed a nationwide recycling network. With the transition from planned economy to market economy system, the country mainly to individual recycling outlets and small enterprises engaged in recycling the rapid rise, forming a renewable resource recycling system, some on the street level recycling of various waste materials of small enterprises, small traders become professional recycling business group. At present, the enterprise engaged in recycling of renewable resources has more than 5,000 companies, recycling processing plant more than more than 3,000 practitioners was more than 1.4 million people, 160,000 outlets across the country, and in some key areas form different industrial scale. At present seven 1st waste material of our country an annual recycling capacity of more than 50 million tons, and annual recycling waste materials worth 45 billion yuan. Currently, China waste steel recovery for 70%-80%, waste nonferrous metals recovery for 85%, waste plastic 25%, waste 1st rubber 47%, waste paper 20%, waste broken glass 13%, scrap car of years recycling volume for milk more million car, waste of years processing pretreatment volume up more than 20 million tons, which waste travel of split solutions capacity has reached more than 10 million tons, waste nonferrous metals and precious metals of recycling and purification capacity also greatly improve, Scrap processing machinery also presents a variety of trends in the development of varieties and specifications, all engaged in the use of renewable resources and processing, as well as product development research institutes is increasing, currently numbering more than more than 10, waste recycling is moving in the direction of industrialization, scale of development.

II, renewable resources recycling industry achieved
renewable resource industry has made significant economic and social benefits. According to the statistics, every ton of scrap steel can be used to save more than 20 tons of iron ore or iron ore steel to save an equivalent of 1. 2 tons every ton of paper used, equivalent to saving 4 cubic meters of wood; relative to pulp alkali saving 40 kg, saving 512, save 47 cubic meters. From 1954 to 1998, there were recycling all kinds of waste and more than 700 million tons, worth more than 500 billion yuan, recycling spent more than 500 million tons of iron and steel, non-ferrous metals scrap more than 6 million tons, 55.6 million tons of waste paper, waste chemicals 14.5 million tons, more than 4 million tons of waste plastics, waste rubber 5.3 million tons, 4.2 million tons of waste glass, equivalent to saving 2.1 billion tons of iron ore for the country, more than 500 million tons of coal, wood conservation 1. 600 million cubic meters, reducing the amount of waste 1.4 billion tons. To alleviate the shortages, tight energy supply situation in China, and for the maintenance of the ecological environment, promoting economic and social development have played a significant role. So we should not look at these numbers, it was these numbers for high-level policy makers in China to provide effective counselling and advisory role.
three, and waste processing technology of development status
in recent years, China degrees old material recycling processing basic rejected has past that "received came in, sold out" of simple of waste moved type of extensive type recycling business mode, preliminary formed has cleaning, and broken, and shear, and except miscellaneous, and except oil, and points selected, and pretreatment processing mode; engaged in regeneration resources recycling using of research units and large constantly research and development waste high value using of technology, and new process and new equipment, These new technologies are applied within the context of, and achieved good economic and social benefits, certain varieties of non-ferrous metals, especially the waste of precious metals, precious metals catalysts, waste recovery of valuable ingredients (such as vanadium, Palladium, etc) technology has reached the international advanced level.
waste recycling technology and equipment has improved continuously, renewable resources information networks have achieved remarkable progress, research and development team has grown, growing range of exploitation and utilization of renewable resources, renewable resources development and broaden the depth and breadth of results is remarkable. Since reform and opening up, especially since in the 1990 of the 20th century, development and utilization of recycled Chinese Yuan business scope and content rich, currently there are several big business: one is recycling as the main distribution companies, is based on the dismantling of used vehicles and machinery and equipment, non-ferrous metals and precious metals recycling and refining, purification, recycling machinery manufacturing, and using 1st material machining composite materials, and so on.
four deepening international cooperation, our country regenerated resources industry
after China's entry into WTO, speed up the pace of economic globalization, foreign economic cooperation in the field of renewable resources also have a faster development. In order to better inform the international peer learning and the Exchange, China's iron and steel raw materials companies, China's environmental protection industry development co, Shanghai material recycling company and other units have joined the Bureau of international recycling organizations, opportunities for cooperation and vision also greatly expanded.
in addition, the national industrial policy is also gradually slopes towards the recycling industry. For many years has taken several important steps to support: the first is a tax policy support. According to rough statistics, since the implementation of preferential policies since each year for the recycling industry directly or indirectly invested more than 600 million Yuan. Second is financial support. Starting from the late 70 's, annually paid millions of Yuan from total project funding, infrastructure for waste and recycling, accumulating allocated more than 200 million. Recycling business in most parts of the infrastructure and technical equipment gradually built up, processing and production capacity is greatly increased. Third, economic policy support. Countries launched the waste and recycling management measures and technical standards, laid the Foundation for the healthy and orderly development of the industry of renewable resources.
for the current existing problems, I believe that there are four factors:
first is policy. At present, there is no waste and recycling laws and regulations, recycling enterprises subject to use restrictions; recycling enterprises are subject to market conditions. Waste recycling and lack a strong long-term incentives and punitive measures, recycling resources industry in the industrial structure of the country's position and role has been set down, recycling of renewable resources there, benefiting the viewpoint has not become the consensus of the whole society, recycling society Foundation is not solid.
the second factor is the economic factor. Due to the waste materials generated scattered, recycling channels diversified, profit-driven, the prevalence of "Li Gan, Li little in, not good to quit," phenomena, reduction in recovery of some varieties, some not easy to recycle the waste materials wastage and pollution is serious. For example, each year about 10 million to 20 million tires thrown away a lot of recycling of waste glass has not been not only waste resources and pollute the environment.
the third factor is the technology factor. Behind overall technological level of China's waste and recycling, waste pretreatment of low level of mechanization and automation, resulting in increased production costs; some rare and precious metals, waste plastics, waste fiber recycling of renewable resources is not high, produce only low grade products. Due to backward technology, enterprises with high energy consumption, low recovery rates, poor utilization, while, due to insufficient investment in science and technology, coupled with treatment facilities behind, resulting in a large number of research projects to carry out, even successful nano research due to the lack of matching funds to promote.
a fourth factor is the enterprise itself. Waste and recycling enterprises engaged in producing small, weak technical force, enterprises do not have the conditions and ability to introduce and develop new technologies, new processes, new equipment, so production costs high, low technology content and added value of the product, thereby blocking the renewable resources to the development of modern industry, the gap with foreign advanced level. The other hand, State-owned recycling business due to the historical formation of personnel, heavy debt burden, weak market competitiveness and capacity to resist risks, poor economic performance, quite a few recycling business losses, enterprises engaged in recycling its development basically hovered at a low level.
