ALUMINUM RECYCLING IS EXCELLENT
Aluminum is a common metal in the Earth’s crust. Today, the most commonly used aluminum is followed by the metal zinc and iron. Thanks to the wide application in life and production, aluminum is consumed more and more. However, it is true that bauxite resources are also limited, but the demand for exploitation and use is increasing day by day. Therefore, the recycling of aluminum scrap becomes a problem. solve the problem of resources and the environment. Protect the environment while saving resources. In parallel with it still ensures the amount of aluminum metal needed for use in life and production.
Outstanding applications from aluminum
Source of scrap aluminum
Aluminum is widely used and popular since the late 1960s. Aluminum is used to make cans, bottles and bottles for beverages, packaging, consumer goods, machinery. Therefore, the use of aluminum scrap receives attention from many people. Some sources of raw materials for aluminum recycling include: household scrap, vehicles, construction, old aluminum and glass windows …
Aluminum recycling is a good problem
Do you know?. Compared to refining new aluminum from bauxite, recycling only 5 percent of the CO2 released into the environment during the process. Therefore, there can be no denying the natural and environmental benefits from the use of aluminum scrap. In addition, the use of recycled aluminum will contribute to limiting mineral mining. From there, it helps to save natural resources, minimize the destruction of the land environment.
Domestic production of aluminum in recent years
Aluminum production uses a lot of electricity and requires a large investment. On average, the top cost of an aluminum electrolysis plant requires 4500 – 5000 USD / ton capacity. Meanwhile, the power needed in the electrolysis process consumes about 13,000 – 14,000 USD / kWh / ton capacity.
Aluminum scrap plays a role in the recycling process
From 1980 to 2004, the total amount of aluminum scrap recycled and used increased significantly. (From 14 million tons to 6.8 million tons). In which, scrap purchase becomes the largest source of raw materials. It is considered the most important source for recycling. In the coming years, it is expected that the source of aluminum scrap supplied from the construction works will increase, while the transportation industry will decrease.
Recycling of scrap aluminum brings benefits to the environment
Aluminum scrap The use of aluminum scrap will save up to 80% energy compared to the production of refined aluminum from raw materials. At the same time will also reduce toxic waste entering the environment from the natural. Reducing the greenhouse effect by reducing the greenhouse effect by 80 million tons per year. Comparing the waste of 15 million cars. In addition, the process of re-cooking scrap aluminum also helps to limit the exploitation of natural resources. And the quality of recycled aluminum is not inferior to refined aluminum from raw materials.
The transformation of the aluminum industry in Vietnam
No one can deny aluminum’s role in all areas of productive life. The recycling of aluminum scrap will help minimize negative impacts on the environment. Do not waste aluminum scrap and focus on exploiting only when the quality recycled aluminum is not impaired. Currently, we do not have an official figure on the issue of aluminum scrap purchasing and recycling in Vietnam. However, according to a preliminary assessment from the craft villages, up to 96% of scrap metal is recycled. It produces a total of over 700,000 tons of product annually.
