The diagram illustrates 10 steps of recycling wasted glass bottles. As is observed, these bottles are required to undergo three significant stages before completely converting into brand new consumable products.
Bottles of beer or fizzy drinks, which have been used up, are categorised as the wasted glass bottles. During the first process, these are accumulated to the collection point with the aim of loading a huge haul. Subsequently, these bottles are transported to the factories on the lorries.
Throughout the second stage, these bottles are pasteurized carefully with high-pressure before being smashed into small pieces in the factories. In the next step, pieces are burnt in furnace at the temperature ranging from 600C to 800C, which is harsh enough to liquefy the pieces. Once new liquid glass has been generated, it is shaped in special glass moulds.
Eventually, after a complicated treatment process, new glass bottles come out. These bottles are then filled up with water or liquids and become completed products, ready for being organized in the stocks of a supermarket.
