Classification and Recycling of Waste Aluminum

1.New scrap aluminum

New scrap aluminum refers to the waste materials, scraps, chips, and other waste generated during the production process of aluminum processing enterprises, aluminum casting factories, and aluminum profile processing enterprises. These wastes contain a large amount of aluminum alloy components and have high recycling value. The appearance and mechanical properties of new scrap aluminum are good, and it can be remelted, cast or processed into new aluminum products, thus having high reuse value.

The main sources of new scrap aluminum are industrial production processes such as aluminum processing enterprises, aluminum casting factories, and aluminum profile processing enterprises. During these production processes, a large amount of waste, scraps, and chips are generated. These wastes contain a large amount of aluminum alloy components. If they can be reasonably recycled and utilized, it will have a positive effect on resource conservation and environmental protection.

2.Old scrap aluminum

Old scrap aluminum refers to aluminum products that have already been used, such as scrap aluminum used in industries such as automobiles, electrical appliances, and construction. After prolonged use and exposure to wind and rain, the appearance and mechanical properties of these scrap aluminum have deteriorated and cannot be directly used to produce new aluminum products. However, these scrap aluminum can be sorted, cleaned, crushed, and processed to separate the aluminum alloy components, and then remelted, cast, or processed into new aluminum products.

The main sources of old aluminum scrap are waste from industries such as automobiles, electrical appliances, and construction. In these industries, a large amount of scrap aluminum is generated every year, such as automobile scrapping, electrical appliance elimination, building demolition, etc. If these scrap aluminum can be reasonably recycled and utilized, it will play a positive role in resource conservation and environmental protection.

3.Recycling and utilization of scrap aluminum

For the recycling and utilization of new and old scrap aluminum, the following methods can be used:

1. Classification collection: For new and old scrap aluminum, they can be classified and collected based on factors such as their composition, appearance, and mechanical properties. Classification collection can improve the recovery and utilization rate of waste aluminum.

2. Cleaning and crushing: For old scrap aluminum, it is necessary to carry out cleaning and crushing treatments to separate the aluminum alloy components. Cleaning and crushing can improve the recovery and utilization rate of waste aluminum.

3. Smelting and casting: For the aluminum alloy components in new and old scrap aluminum, smelting and casting can be carried out to reprocess them into new aluminum products. Smelting and casting can improve the recovery and utilization rate of waste aluminum.

4. Processing and Reuse: For the aluminum alloy components in new and old scrap aluminum, processing and reuse can be carried out to directly or indirectly use them in the production of new aluminum products. Processing and reusing can improve the recovery and utilization rate of waste aluminum.
