Benefits of recycled glass

Manufacturers benefit from using recycled glass in several ways.

Recycled glass reduces emissions and consumption of raw materials, extends the life of plant equipment such as furnaces, and saves energy. Recycled glass can be substituted for up to 95% of raw materials and reduces costs for manufacturers while also benefiting the environment—a nice marketing feature.

  • Requires less energy: It is generally asserted that cullet requires 25-30% less energy to melt than virgin batch materials.
  • Lowers air emissions and reduces carbon footprint: One ton of carbon dioxide is reduced for every six tons of recycled container glass used in the manufacturing process.
  • Helps protect the environment: Cullet reduces the need for precious raw materials and the water used to extact them.  Using 1 ton of cullet replaces the need for 1.2 tons of raw materials.  Also, recycling glass saves landfill space and helps extend their life. 
  • Supports recycling: Consumers are looking for higher percentages of recycled content and recognize the value of a closed loop recycling process.
