|Energy Savings Potential||
Increased availability of suitable cullet helps reduce energy consumption.
In one plant, recycling rate for internally produced cullet has been increased from 30% to 75% with the installation of a cullet crusher (Worrell et al., 2008. p.56).
|CO2 Emission Reduction Potential|
Installation of a crusher enabled increasing the recycling rate of internally produced cullet from 30% to 75%, resulting in US $190 000 [1997 dollars] cost savings due to reduced waste handling and material purchases. Payback time was 3 weeks (Worrell et al., 2008. p.56).
