The diagram illustrates the recycling process of aluminum cans. The process is composed of several stages, each crucial for converting used aluminum cans into reusable material.
Firstly, used aluminum cans are collected. Following the collection, the cans undergo a cleaning, sorting, shredding, and compressing process. This step ensures that the cans are free from contaminants and are properly prepared for the next stage.
Once cleaned and sorted, the aluminum is heated and melted in a furnace. The molten aluminum is then poured into molds to create large blocks or ingots. These ingots are subsequently rolled into sheets that are 3-6mm thick.
The final stage involves reusing these aluminum sheets to manufacture new cans. It is noteworthy that in the UK, 74% of aluminum cans are recycled and reused, showcasing the efficiency and effectiveness of the recycling system.
Overall, the recycling process of aluminum cans involves collection, cleaning, melting, rolling, and reusing, forming a closed-loop system that promotes sustainability and reduces waste.
