The given diagram illustrates the process by which glass bottles are recycled. Overall, it is evident from the information supplied that there are three main phases involved, namely collecting, processing, and redistributing.
Prior to the actual processing of the glass bottles, it is necessary for used bottles to be gathered and placed at the collecting point. They are then delivered by trucks to the cleaning plant.
The second stage of the recycling process, meanwhile, entails bottles sorted by colour into green, brown, and clear ones before being cleaned by high-pressurised water. Subsequently, these bottles are shipped to glass factories, where bottles are crushed into glass pieces. After that, they are heated in a furnace in order that these bottles become liquid. Then, this liquid is put into a glass mould, sometimes adding liquid glass, eventually forming a brand-new bottle.
In the third and final phase, after all these new bottles are either filled or packed, they are transported to supermarkets, available for customers to purchase. At this point, a cycle has been completed and a new cycle will begin.
