The illustration demonstrates the process of manufacturing aluminium cans from recycling.
Overall, there are eleven steps in the sequence, starting with waste items, followed by the conversion of cans into small pieces, and ending with the newly produced cans for consumption.
The first four steps involve the transformation of the raw material. Initially, waste things are collected and deposited into factories. After this, these are cleaned with water and conveyed into the crushing machine. Subsequently, crushed small pieces are extracted, ready for the next stage.
The collected amount of crushed pieces undergoes a chemical process, then experienced a heating process to convert to liquid. In the following step, the liquid is moulded into a can form. During the following stage, these are sent for weighing by a weight machine. After that, these are rolled by rolling equipment, resulting in new cans. After all, aluminium can be made in several stages.
