Measures implemented and savings made

Intensive and in-depth analysis has resulted in the identification of promising potential for the reduction of the consumption of natural gas and electricity. This has been summarised in a catalogue of measures. A significant reduction of the consumption of natural gas can be partially achieved e.g. by improving waste heat utilisation and intelligent burner and pre-heating combustion air control, amounting in individual cases to up to 200,000 Nm³ natural gas per year and measures implemented.
The amortisation period for the implemented measures was less than three years.
