The diagram illustrates the stages involved in the process of glass recycling.
Overall, it can be seen that used glass is collected, processed and transformed into new products before being distributed again.
In the first stage, people place used glass bottles into special recycling containers. These containers are then collected by large trucks, which transport the glass to a recycling factory.
At the factory, the glass is sorted according to colour and then crushed into small pieces. After that, the crushed glass is thoroughly washed to remove any dirt or impurities.
In the next stage, the clean glass is melted in a furnace at a very high temperature. Finally, the melted glass is shaped into new products and delivered to shops for reuse.
