Aluminum recycling has many benefits for the environment, mainly reflected in the following aspects:
1. Reduce resource mining
The main source of aluminum is bauxite, which is a non-renewable resource. By recycling aluminum products, the demand for bauxite mining can be greatly reduced. This helps to protect the limited mineral resources on the earth, maintain ecological balance, and avoid land damage, vegetation damage and impacts on surrounding ecosystems caused by large-scale mining.
2. Reduce energy consumption
Compared with extracting primary aluminum from bauxite, recycling aluminum requires much less energy. The production of primary aluminum requires multiple complex processes and consumes a lot of electricity and other energy. Aluminum recycling mainly involves the collection, sorting, melting and refining of discarded aluminum products, and its energy consumption is only a small part of the energy consumption of primary aluminum production.
3. Reduce pollutant emissions
Since energy consumption is greatly reduced in the aluminum recycling process, pollutant emissions generated by energy production and use are also reduced accordingly, such as greenhouse gases and harmful gases such as carbon dioxide and sulfur dioxide. At the same time, it also reduces the discharge of pollutants such as wastewater and waste residue generated during bauxite mining, mineral processing and smelting, reduces the risk of pollution to soil, water sources and air, and helps improve environmental quality and protect the ecological environment.
4. Reduce the amount of landfill
If discarded aluminum products are not recycled but directly landfilled or incinerated, it will not only occupy a large amount of land resources, but may also pollute the soil and groundwater. Through recycling, these discarded aluminum products can be converted back into useful resources, reducing the pressure on landfills and reducing the negative impact on the environment.
