The diagrams illustrate the process of manufacturing and recycling glass containers, such as bottles. The overall procedure is divided into two main stages: glass production and glass recycling.
In the first stage, raw materials including sand, soda ash, limestone, and other chemicals are combined and melted in a furnace at a temperature of approximately 1500°C. Once the materials are fully liquefied, the molten glass is shaped into various containers, such as bottles.
The second diagram outlines the recycling process. Used glass containers are first collected and sorted according to their color. After sorting, the glass is thoroughly washed to eliminate any impurities. The cleaned glass is then crushed and melted again. Finally, the molten recycled glass is molded into new products, completing the cycle.
Overall, the diagrams highlight a sustainable system in which glass containers are not only produced from raw materials but also reused through a structured recycling process, reducing waste and conserving resources.
