The diagram shows the recycling process of used aluminum cans, starting from initial collect and process to creation of new cans and their return to the market for reuse.
Overall, this is a circular process consisting of seven main stages, divided into two parts: collection – preparation and recycling – production. The process begins with the collection of used aluminum cans and ends when new cans are produce, and returned to consumers. Clearly, aluminum cans must cleaning, sorting, melting, and rolling before being manufacture into new products.
In the first stage, used aluminum cans collected by people from recycling bins and transported to the recycling facility using vehicle. Next, the cans are cleaned to remove dirt, labels, and any liquid inside. After cleaned, the aluminum cans are sorted. At this step, other materials such as other metal or plastics are remove to ensure that only aluminum cans that meet the standards and transferred to the next stage.
After the sorting process is done, the aluminum cans are heate in a furnace at high temperature until they turn a liquid. Then the melt aluminum is then rolled into in sheets using rolling mills. Next to the second stage, these aluminum sheet cut and shaped to produce new aluminum cans. Finally, the new cans are filled with the drink and returned to the market for consumers to use, done the completing the closed-loop recycling cycle.
