The diagram illustrate the recycling process of glass, starting from collection and ending with new glass products.
First, used glass bottles are collected and send to a purification center, where any unwanted materials are removed. After this, the glass undergo a fining process, where it is broken down into smaller pieces using different mechanical tools.
Next, the small glass fragments is sorted using an optoelectronic system to separate impurities. The cleaned pieces then goes through another purification step before entering the cullet melting stage, where they is melted at high temperatures.
After melting, the molten glass is formed into new bottles through molding process. Finally, the finished glass products is ready for use and re-enter the cycle when disposed properly.
Overall, the process involves several steps of cleaning and refining before used glass can be turned back into usable items.
