The diagram illustrates the process of how glass bottles used for drinks are recycled. Overall, the process is cyclical, consisting of twelve steps, with each stage leading efficiently to the next to achieve a glass drinks bottle.
The process begins with the recycled glass, which is combined with materials such as soda ash, sand, and other components. It is then transferred into the furnace at approximately 1500 degrees. Next, the foreheating happens when the temperature homogenizes, meaning it is made the same. After this, the glass goes into the cutting machine to cut identical pieces for each glass. The identical pieces then went into the forming machine so that the glass turned into moulds. It’s supposed to cool under 1150 degree celcius.
Subsequently, rapid cooling starts happening where it’s supposed to cool under 500 degree celcius. This leads to conditioning that strengthen to 1200 degree celcius to under 500 degree celcius. Then, when it finally cooled to 120 degrees, they’ll spray a coating for a smoother finish. Finally, the glass will go through a quality check, if it passes, it’ll be package and if they rejected it it’ll go through the process again.
