Carbon neutral glass production today

Steklarna Hrastnik will present the process of manufacturing its most sustainable glass bottles and future options for upscaling the carbon neutral production. The melting of glass for first initial batch of most sustainable bottles involved renewable energy sources, green hydrogen gas and external cullet collected from waste recycled glass. Hydrogen and Oxygen were used as a fuel, thus only emission produced in the glass making process was water vapour. Our most sustainable glass bottle yet is not only a milestone for Hrastnik1860, but above all represents a proof that it is possible to make the first steps towards the much-needed transition already today.
