About products and suppliers

Aluminium scrap refers to discarded or waste materials composed of aluminium bars and sheets that can be recycled and reused. Recycling aluminium scrap is an essential practice in many countries because it helps conserve natural resources, reduces energy consumption, and minimizes the environmental impact associated with mining and purification of bauxite. Bauxite is one of the most abundant aluminium ores consisting of impure aluminium hydroxides along with a lot of silica, iron, and other impurities. It is purified to a white powder of aluminium oxide, and through electrolysis, the white powder forms pure aluminium. From the above explanation, there is a great need to embrace aluminium scrap metal pieces because extracting raw aluminium is time-consuming and robs the earth of its core ores. Plus, aluminium scrap pieces are affordable and easily available.

What are the sources of aluminium scrap?

Online wholesalers offering quality aluminium scrap get it from different sources. One of the major aluminium scrap types is consumer goods. Globally, around 280 billion aluminium cans for beers and sodas are produced annually. Cumulatively, cans alone account for over one million tonnes of waste aluminium. So rather than throwing them away, they are collected together with other items like used aluminium foils and aluminium kitchen utensils to be recycled.

Aluminium from building materials, window frames, doors, and other construction-related items fall under construction and demolition waste. This aluminium scrap's value is usually high since most construction sites are made from quality metals. Additionally, the weight of aluminium scrap from building sites is usually higher compared to that of consumer goods. Due to this difference in quality, construction aluminium scrap prices are usually higher.

Another eco-friendly source of aluminium scrap is the transport industry. End-of-life vehicles, aircraft, and ships contribute a significant amount of aluminium scrap, which is obtained by stripping off parts.

The recycling process of aluminium scrap

The recycling process of aluminium scrap starts from collection. aluminium scrap metals are collected from various sources and transported to recycling centers. At the center, the collected scrap is then sorted to separate different types of aluminium alloys and remove contaminants. After sorting, coatings, paints, and other impurities are removed using special chemicals and solvents. Finally, clean aluminium scrap pieces are then shredded and melted down to form aluminium ingots. Ingots are then sold to overseas customers at a certain aluminium scrap rate. Even though the aluminium scrap price per pound may fluctuate, it has seen tremendous growth rates over the years due to the increase in demand for quality aluminium.

Recycling aluminium scrap is an important step towards sustainable resource management and environmental responsibility. By participating in aluminum recycling programs and buying aluminium scrap, individuals and businesses can make a positive impact on the environment and support the circular economy. In the end, relying on aluminum scrap requires significantly less energy compared to producing aluminum from raw materials. It can save up to 95% of the energy needed for primary aluminum production. Furthemore, buying scrap aluminium from online wholesalers reduces greenhouse gas emissions, air pollution, and water pollution associated with primary aluminum production.
