Since the cap on the bridge
Steel is accompanied in all areas of life. Like any other material which enables various treatment with low production costs. Over 2,000 varieties of steel is its use in relation to their properties - hardness, and flexibility. Steel is subjected to a number of technological processes, as well as cutting, rolling, stretching, compression. An important advantage of steel products is their toughness and ease of recycling of waste material.
After about 20 years, as many as 70% of all steel products back to the secondary circuit.
With well-organized global recycling system every second ton of steel produced in the world comes from scrap.
International cooperation recyclers and manufacturers of steel make the user re-use about 400 million tons of waste each year.
Currently, the steel industry participates in the development of innovative processes of obtaining raw materials more easily engaged in the recycling. Recycling - although widely recognized as a key instrument for the protection of the environment-faces barriers in various industries.
The exception is the iron and steel industry. Steel recycling has a long tradition.
Steel scrap undergoing multiple treatment does not lose its properties.
As a result of multiple penetration is achieved premium material.
Steel due to its unique magnetic properties is still most effectively used construction material.
With the development of the global market economy entered the "era of recycling." Recycling has become an integral part of it. Currently, scrap and steel industry operating on an international scale, and with an expanding range of joint responsibility for the management of waste steel products placed on the market and for the purchase of scrap to produce secondary raw material.
The international market for recycled materials is importance due to reduce natural resources, is a key partner in the area of environmental protection.
Scrap Companies are the main link in the "loop" recycling scrap metal, they are responsible for the collection, purchase, storage, collection and delivery of raw materials to customers.
It is their business, steel products used by households, dismantled production facilities or car bodies are to be recovered and transported to the mills to produce the next intermediate or finished products.
SCRAP ENERGY BANK
Metal recycling protects the environment, not only due to waste management, but also by reducing energy consumption in the production process.
Stainless repeatedly processed - without losing quality or their properties - a kind of "market power" because its processing in the secondary process consumes far less energy compared to the amount of energy needed to produce it in the original. Steel due to its energy-saving properties exceed the quality - as defined by the impact on the environment - other raw materials, such as plastic, glass, or paper.
Steel recycling saves 74% of the energy needed to primary production and the recycling of aluminum, this value increases to 95%.
Current knowledge about the process of recovery and processing and the use of steel in various industries and combinations of materials opens up new perspectives for recycling methods, and thus increases the amount of steel in the "recycling loop".
MINERALS A RECOVERY
Note that natural sources of materials for the production of steel are not renewable resources, so grows the importance of the application of secondary raw materials in production. Currently, the world varies recovery of metals at a level of from 80% to 100% depending on the products.
The steel recycling helps to reduce emissions of pollutants into the atmosphere for up to 86% compared to the emissions in the production of ore. The processing of one tonne of waste can save 1.5 tons of ore, 0.5 tons of coke, and other materials, reduces the amount of waste water and sewage discharged. However, one ton of the recycled aluminum saves 4 tons of bauxite and 700 kg of fuel, avoid air emissions 35 kg of aluminum fluoride.
