The diagram illustrates the process of recycling glass.
Overall, the cyclical process consists of 5 stages, starting with the gathering of used glass from the bins around the city and transporting the new products for consumers. It is also worth mentioning that the process requires a wide range of special equipment and machinery.
The first set of stages involves relatively active work to be done. Initially, garbage trucks collect glass bottles from the bins and deliver them to the treatment plant, where they are cleaned in a washing and sterilising machine for the next stages.
The rest of the phases mainly include heating and cooling machines. Once the glass has been washed, it is placed in a crushing machine, after which it is heated and melted into a liquid. Then the hot liquid is poured into a moulding machine where it gets a new shape after it is cooled. Finally, all bottles are transported to companies such as Coca-Cola, Pepsi, and others.
