subject: Recycling Aluminum Industry [print this page] From the current view of the world's consumption structure of aluminum, recycled aluminum industry has become an integral part of the aluminum industry. Recycled aluminum with aluminum do not have the advantages of aluminum per ton per ton of recycled aluminum and energy savings compared to up to 95%, C02, and greatly reduce harmful emissions are conducive to environmental protection.
Aluminum is a fully renewable and can be recovered without compromising the quality of the metal. Aluminum light weight applications in the automotive industry increased focus on Europe and the United States automobile manufacturers, such as the U.S. General Motors Corporation, Ford Motor Co. and Germany's Volkswagen, BMW car companies are strengthening and development of aluminum components in the car the application of automotive aluminum has been successfully developed, its work to reduce vehicle weight, save fuel, there are remarkable advantages conducive to environmental protection.
According to the World Bureau of Metal Statistics published in 27 countries and regions of the data, in 1998, 7.5942 million tons; in 2002 it reached 7.9063 million tons, with an average growth rate of 1.0%; while the world's primary aluminum production over the same period were 22.6539 million tons and 26.1375 million tons, an average annual growth rate of 3.6%. The annual average growth rate of primary aluminum recycled aluminum than the annual average growth rate of higher than 2.6 percentage points. Some experts believe that this trend is reasonable because of the scrapping and recycling of aluminum products are generally lagging behind after the occurrence of primary aluminum consumption for some time. It should be noted that, as society increases the amount of metal accumulation, recycling volume is increasing year by year.
The United States in 2001 recycled aluminum scrap aluminum produced 2.982 million tons, exceeding the primary aluminum production. In 2001 the U.S. recycled aluminum beverage cans accounted for 55.4% of total production, recycling aluminum 755,000 tons. Alcoa has established a new scrap recycling target by 2020, aluminum products will have 50% recycled scrap the production.
Brazil's total annual capacity of aluminum cans are now 10.2 billion in 1991, began recycling aluminum beverage cans. South America, three major powers - Brazil, Argentina and Chile, aluminum beverage production centers are located in Brazil, but also South America is now spending aluminum beverage cans than any other country. In 2001, the three countries a total consumption of 11.8 billion aluminum beverage cans, Brazil accounts for 89%, reaching 10.5 billion. Brazil attaches great importance to recycling aluminum beverage cans, 15 million people engaged in recycling aluminum beverage cans in 2001, a return rate of 85%, ranking first in the world, more than Japan's 82.5% recovery rate. Brazil, then the weight of recycled aluminum cans to reach 119.5 thousand tons, equivalent to 9 billion aluminum cans weight.
Japan is an aluminum consumption in the country is completely dependent on imports. Recycled aluminum demand has been rising, auto parts and export of aluminum alloy of the number of cars in that the aluminum scrap price hikes affecting related industries and aluminum cans. Is usually below 100 yen per kilogram of waste aluminum cans rose to 125 yen or 130 yen. The end of 2002, aluminum alloy recycled by the end of production in 2001 increased 18.1%, sales increased 16.8%.
Spain's current primary aluminum production capacity of 370,000 tons / year, renewable aluminum capacity of 250,000 tons / year, re-melting capacity has also increased. Norsk Hydro's remelting in Spain to establish a new recycling plant, started in 2001 and trial production of aluminum extrusion billets, the current production capacity has reached 60,000 tons / year of raw materials are clean and the local production of aluminum scrap aluminum extrusion plant business generated waste and other materials, such as grain refining agent and master alloy powder, as well as imports of aluminum ingots.
World Renewable aluminum industry there is a new feature, which is large auto companies and the establishment of the closed-loop Alcoa aluminum scrap recycling system. The world's major car companies are paying attention to and study of new aluminum scrap recycling system, and attaches importance to its future market potential and development space.
Recycled aluminum in the world has its own laws of development of the industry, market demand and prices is the key to reduce the cost of production of waste recycled, aluminum scrap recycling process development of new technologies, new equipment imminent. In the automotive, packaging and construction industries, aluminum scrap recycling has tremendous market potential and development prospects.
China's aluminum recycling industry has developed rapidly in recent years. In some parts of the country has formed a specialized distribution market and production base. In Guangdong, Zhejiang, Jiangsu, Hebei, Henan, Shandong, Chongqing, Shanghai and other places, a number of large and medium sized enterprises are the rise of recycled aluminum, recycled aluminum industry in China has laid a foundation. But overall, China's aluminum industry, the development of renewable there are still many problems, mainly reflected in: product quality; variety of structural problems; the scale of production problems; smelting equipment problems; melting additive development issues; scrap aluminum pretreatment technology and equipment problem; production conditions and environmental pollution problems; market disorderly competition; tax policy matching problems, and so few. China is now recycling aluminum scrap the total 100 million metric tons, engaged in waste recovery and miscellaneous aluminum smelting and the use of scrap aluminum production of various products, the number of firms than in 3000.
