Growing its decoration capacities in keeping with market demand, Stoelzle has invested €1m in a new high-speed spraying line at its Czestochowa site in Poland. The Austrian glassmaker has also joined the ZeroC02Glas project to develop a CO2-neutral glass melting process.
A fourth spray line at glassmaker Stoelzle’s decoration site in Czestochowa, Poland came into service last month. It represents an investment of €1m. Set up to process containers up to 200mm in size, it will focus on Perfumery and Cosmetics as well as pharmaceutical bottles and has daily output of more than 100,000 sprayed bottles.
In line with Stoelzle’s sustainability strategy, the new decoration line uses water-based inks.
ZeroCO2Glas project for CO2-free glass melting
In other news, the glassmaker, which is aiming to reduce CO2 emissions by 50% by 2030 and targeting carbon neutrality by 2050, has highlighted its involvement in Germany’s ZeroCO2Glas project, which is currently in its second stage of upscaling.
With up to 85% of the energy required in glass manufacturing used for melting, the consortium-led R&D project aims to develop a new type of energy-saving glass melting furnace that will enable CO2-free glass melting. The hybrid furnace (combining hydrogen-oxy and natural gas-oxy firing with electricity), will be set up in Aachen, Germany.
The melting technology aims for a 15% reduction in energy consumption compared with conventional furnaces, according to the glassmaker.
“Energy savings will be achieved by using alternative and CO2-free raw materials, avoiding unnecessary humidification of the batch, as well as reducing the dwell time of the glass in the furnace due to a special melting process and the improved new furnace design,” Stoelzle explained in a statement.
The total project is expected to cost around €14.94m, with the German Ministry for Economy and Climate providing a maximum of €8.38m. The project is driven by IPGR (International Partners in Glass Research), of which Stoelzle has been a member since 2020.
