The diagram demonstrates how used glass bottles are recycled into new ones.
In summary, this is a three-stage process which begins by collecting and transporting wasted glass containers, and then disassembling them into raw material, before combining the latter with new liquid glass to make new bottles ready to be sold in supermarkets.
The first stage begins when such used products are gathered in collection points and transported via vans to recycling centers where processing takes place.
In stage two, the bottles are subjected to high pressure water to yield either clear, green, or brown material which is then transported to glass factories. The substance is then made into glass fragments which are burnt in ovens at temperatures reaching 600 to 800 Celsius to produce recycled liquid glass. This, along with new liquid glass, is then used put in shaping molds to form new glass bottles.
Finally, stage three involves filling the new products and transporting them to supermarkets where they are sold before the cycle starts again.
