Stoelzle Glass Group is investing €22 million in its Austrian site of Stoelzle Oberglas in Köflach this autumn.
The demolition of the previous flint glass furnace started this month, and had produced approx. 500,000 tons of glass containers for pharmaceuticals, food, beverages and cosmetics over the last eight years.
The larger furnace will be constructed in eight weeks, and will have a daily capacity of around 270 tons – an improvement in terms of energy efficiency and sustainability.
The furnace will use the latest melting technology. It is estimated the amount of energy used to melt the glass will be reduced by approx. 13% per ton of glass.
Improved e-boosting will also use more green electricity to reduce the consumption of natural gas.
This, in combination with adding approx. 20% of PCR cullet to the batch, will substantially reduce the CO2 emissions of the factory’s glass production – an important step towards a 50% reduction of CO2 emissions by 2030.
