2. Recycling steps
The linear life cycle of aluminum begins with the extraction of the ore, i.e., bauxite, which is then converted into alumina using the Bayer process, and then into aluminum by electrolysis, also known as the Hall-Héroult process (figure 4 ). The aluminum is melted into a liquid form. From this stage onwards, the life cycle branches out, the corresponding material flows are smaller, and the path followed depends on the end application ...
