The diagrams explain the way in which glass containers, such as bottles, are produced and recycled.

    Overall, the process consists of 4 stages of glass production and 5 stages of glass recycling. The glass production process begins with mixing the materials and ends up with the finished glass containers. And the glass recycling process begins with the collection of used glass and ends up with moulding them into new products.

    First of all, sand, soda ash, limestone, other chemicals are mixed. After that, the raw materials are melted in a glass furnace, where they are heated with an approximate temperature of 1500 Celsius. Then the melted materials are shaped in the molten glass bowling.  Next, they are stored in the glass containers after they are shaped.

    In the glass recycling process, the used glasses are collected first. Next, they are sorted depending on their color. After that, the sorted used glasses are washed to remove their impurities. Then, the washed materials are crushed and melted. Finally, the crushed and molten yields are turned into new products after they are moulded.
