The diagram illustrates how aluminum cans are recycled.
Overall, this manufacturing process consists of eleven stages, beginning with collecting waste on a truck and ending with producing new cans. This linear process lasts for six weeks.
Initially, the garbage truck gathers waste, and transports it to a recycling factory. After that, the collected cans are watered by a special hydrant to make them softer. Then, several cans are compressed together into a rectangular shape.
Next, they are transferred to another factory to undergo processing. First, the cans are processed with chemicals to erase any impurities. Upon completion of this stage, they are heated on fire so they become softer and easier to be shaped. After this step, the cans are put into moulds that are prepared beforehand. After passing the weighting process, they are rolled on a special equipment to form the shape of a can. Finally, new cans are produced, and they can be used by consumers.
