Aluminum scrap refers to discarded aluminum materials that can be recycled to produce new aluminum products. It is a highly valued commodity due to its cost-effectiveness and environmental benefits, as recycling aluminum significantly reduces energy consumption and greenhouse gas emissions.
1. Product Overview
Aluminum scrap is sourced from various end-of-life products, manufacturing processes, and consumer goods. It can be categorized into different grades based on purity and form, including:

Type Description

Post-Consumer Scrap : Scrap is obtained from used products like cans.

Pre-Consumer Scrap
Scrap generated during manufacturing processes.

Dirty Alloys
Scrap that contains impurities or mixed alloys.

2. Recycling Process
The recycling of aluminum involves several steps:

Collection: Gathering scrap from various sources.
Sorting: Classifying scrap by type and quality.
Melting: Heating aluminum scrap to its melting point.
Casting: Forming new aluminum products from the molten metal.

3. Benefits of Recycling Aluminum

Energy Savings: Recycling requires only about 5% of the energy needed to produce new aluminum from ore.
Reduced Waste: Diverts scrap from landfills, promoting sustainability.
Economic Value: Recycled aluminum can be sold at a higher value compared to other recycled materials.
