The beginning of the process often involves the sorting of glass by color, so the recycled glass will be the same color. Then, “a mechanical processing system breaks the glass into small pieces called cullet”. Labels, pieces of metal, and other non-glass items are filtered out with magnets, screens, and vacuum systems (this may happen before the glass is crushed into cullet). The cullet is then “blended in measured amounts with silica sand, soda ash, and limestone, and placed in a furnace which melts it into molten glass”, and then the molten glass is formed into usable products.
These steps may happen at different facilities. Sometimes recycling centers sell the cullet to glass manufacturers, or whole glass containers are sold by the collection agency to be recycled.
