Aluminum scrap refers to discarded or surplus aluminum materials that can be recycled and reused. It is commonly found in old vehicles, appliances, construction materials, and packaging. Aluminum scrap is categorized into different grades, such as clean aluminum, which is free from contaminants, and mixed aluminum, which may contain other materials. Recycling aluminum scrap conserves energy, as producing new aluminum from raw materials requires significantly more energy. The recycling process involves sorting, cleaning, and melting the scrap to create new aluminum products. This contributes to environmental sustainability by reducing the need for mining and minimizing waste.
