the provided diagrams illustrate the process of manufacturing glass containers and how used glass is recycled.
overall, it is noticeable that there are four steps in the process of producing glass, starting at the preparation of materials and ending at creating glass containers. Moreover, recycling glass has five steps, from collecting glass to making new products.
in terms of glass production, the process begins with mixing several materials, including sand, soda ash, limestone and other chemicals. Secondly, glass undergoes a melting process in a furnace at an elevated temperature of 1500 degrees Celsius. Then, molten result is blown to make well-shaped glass. After this point, glass containers are created and used in daily life.
from the perspective of glass recycling, used glass is collected at the first step. following that, glass is sorted by color then to be washed in order to remove impurities. at the final step, glass is ready for forming into new products by a mold after being crushed and melted.
