Recycled glass is broken before being delivered to the manufacturer in order to reduce volume.
This broken glass is known as cullet. The cullet is passed through a magnetic device to remove all bottle tops while a vacuum process will relove all plastic and paper attachments. The cullet is then ready to be melted down. Cullet melts at a much lower temperature than the sand, lime and soda. It uses 32 percent less energy than the basic process - a huge saving.
