Glass Packaging Institute Celebrates Recycle Glass Week
September 10, 2010
The second annual Recycle Glass Week will be held September 12-18, 2010 and the Glass Packaging Institute
- Saves raw materials - Over a ton of natural resources are conserved for every ton of glass recycled, including 1,300 pounds of sand, 410 pounds of soda ash, 380 pounds of limestone, and 160 pounds of feldspar.
- Lessens the demand for energy - Energy costs drop about 2-3% for every 10% cullet used in the manufacturing process.
- Cuts CO2 emissions - For every six tons of recycled container glass used, a ton of carbon dioxide, a greenhouse gas, is reduced. A relative 10% increase in cullet reduces particulates by 8%, nitrogen oxide by 4%, and sulfur oxides by 10%.
- Extends furnace life - Including cullet in the manufacturing mix makes it less corrosive and lowers the melting temperature (from 2800 degrees F. to 2600 degrees F.), prolonging furnace life.
- No processing by-products - Glass recycling is a closed-loop system, creating no additional waste or by-products.
