Increased Cullet UseCosts & Benefits
|Parent Process: Melting and Refining|
|Energy Savings Potential||
As a general rule, every 10 % of extra cullet results in a 2.5 – 3.0 % reduction in furnace energy consumption (IPTS/EC, 2013. p. 314)
Based on a study in german-speaking European countries, energy savings are estimated at around 8 MJ for every percent increase (by weight) in cullet use (Worrell et al., 2008. p.67)
|CO2 Emission Reduction Potential|
The use of cullet generally results in significant cost savings as a result of the reduction in both energy and raw material requirements. Economics will depend on availability and cost of cullet.
