BOMMA Cullet saves 30–40% of energy costs compared to batch melting. 

The melting temperature is only 1250–1280 °C (2282–2336 °F), for cast glass just 850–900 °C (1562–1652 °F). Together with the shorter melting time you save 30–40% of energy costs compared to melting a batch and 15–20% to other cullet manufacturers.
