Waste hardware and electric appliance including waste motor, scrap wire and cable and scrap metal appliances etc. three categories can be obtained after dismantling scrap steel, scrap copper, scrap and other scrap metal and waste plastics. The research shows that after the dismantling of a ton of waste hardware and electrical appliances, 97% of the above-mentioned useful materials can be obtained, and only 3% of the available ones are not available, which greatly supplements the shortage of metal resources in china.
However, the controversy over the import of scrap hardware and electrical appliances has been going on for a long time. As early as the 90s of last century, when China imported foreign waste just started, because the laws and regulations were imperfect, people's environmental awareness was poor, and the dismantling technology was backward, resulting in environmental pollution. In some places, waste electrical machinery is broken down in front of every house and in front of the house, polluting the soil, and waste wires and cables which are not disassembled by hand can be burned outdoors, polluting the air environment. Waste hardware and electrical appliances contain a large amount of useless waste, which increases the difficulty of disposal.
Since the beginning of this century, the state has increased supervision of imported waste. The Ministry of environmental protection on imports of waste hardware and electric appliance and implement designated zone management; quality inspection administration implement the registration of foreign suppliers and domestic consignee; customs requirements on imported waste hardware and electric appliance category of shipment, prohibited mix, prevent entrainment and smuggling. After taking these measures, dismantling enterprises into the park, standardized dismantling, unified treatment of pollutants, mechanized dismantling gradually increased, the current situation of imports of scrap hardware, electrical waste products greatly improved.
I. advantages of imports of scrap hardware and electrical appliances:
1., the economic benefits are obvious, which supplements the shortage of metal raw materials in china.
In the dismantling dismantling technology, technical level and mechanical dismantling by leaps and bounds, crusher, coppermetersmachineand, stripping machine, heat cleaning furnace emerge in an endless stream.
Research shows that the dismantling of a ton of waste motor can get 70%~75% scrap, 8%~10% copper, 12%~16% aluminum scrap, waste plastic 2%~3%, do not use accounted for only 3%; after the dismantling of scrap wire, cable to 45%~48% copper, waste plastics 50%, about 3% of the non use; dismantling waste electrical hardware available 5%~8% 6%~11% 70%~75% copper, scrap, scrap iron and steel, can not use only 5%~6%.
According to statistics, our country from 2002 to 2014 thirteen years, the total imports of scrap hardware, electrical waste 73 million 870 thousand tons, accounting for 11% of solid waste imports. A total of 19 million 260 thousand tons of scrap dismantling scrap, 8 million 780 thousand tons, about 33 million 530 thousand tons of steel scrap, stainless steel scrap 1 million 800 thousand tons, 10 million 480 thousand tons of waste plastics, can not use only 2 million 880 thousand tons. Respectively, reducing the amount of 1.44 tons of iron ore mining, saving 76 million 500 thousand tons of copper concentrate, reducing the exploitation of 29 million 800 thousand tons of bauxite, saving 13 million 400 thousand tons of crude oil. The economic benefit of resource reuse is considerable, which greatly supplements the shortage of metal raw materials in our country.
2., prominent environmental benefits, energy-saving emission reduction effect is obvious, reducing environmental pollution.
Environmental benefits are embodied in two aspects: energy saving, emission reduction and reduction of two pollution.
Statistics show that from 2002 to 2014 13 years, compared with the primary metal production, China's imports of waste hardware and electric appliance total energy saving 58 million 790 thousand tons of standard coal, water-saving 6 billion 800 million cubic meters, less row of solid waste 67 tons, 2.2 tons less carbon dioxide, 7 million 510 thousand tons of sulfur dioxide emission reduction. It contributes greatly to environmental protection and energy saving and emission reduction.
3., significant social benefits, providing jobs to solve the shortage of labor.
The renewable metal industry is a typical labor-intensive industry, involving import, recycling, dismantling, smelting, processing, trade, services and other links, providing a broad career opportunities for the community. Direct employment of hundreds of thousands of people, indirect employment of millions of people.
China along with the accelerated pace of urbanization, small towns are required for dismantling the utilization of waste, such as Guangdong Zhaoqing renewable resources processing park, construction of the park surrounded by residential areas, supporting shops, restaurants, schools, post offices, banks and service industries. The renewable resources industry has promoted the construction of urbanization in China, and has made great contributions to social harmony.
4., promote international exchanges and cooperation
At present, all regions of the world have recycling industry organizations, such as the United States Bureau of international recycling, scrap recycling industry association, China Nonferrous Metals Industry Association recycling metal branch, the Middle East, the India Association of renewable resources recycling association, member enterprises from hundreds to thousands, the association held every year 1~2 annual meeting and exhibition, jointly to discuss the development trend of international recycling industry and prospects, promote trade exchanges. Conference and exhibition is very spectacular, forming a beautiful landscape, the association between the representatives of the participants and organizations involved in recycling enterprises, each conference will promote the trade turnover of billions of dollars, greatly promoted the development of China's foreign trade.
