The diagram below illustrates how glass is recycled

The figure depicts the process of glass recycling.
Overall, it can be seen that the process by which glass is recycled is a multistep, cyclical process which consists of three main stages: collection, processing and distribution.
In the first stage, customers place used bottles in collection bins, and the bottles are collected by large trucks.
In Stage 2, the bottles are taken to a cleaning plant, where they are cleaned with high-pressurised water. They are then separated according to colour (green, brown or clear), and taken to a glass factory, where they are crushed into pieces. The pieces are melted in a furnace and the resulting liquid, together with new liquid glass, is poured into a bottle mould.
In the third and final stage, the new bottles are filled and packed, and then sent to supermarkets, where the customers buy them and the process begins again.
