For us, sustainability is a prerequisite for being successful in future, and has so been included as a key aspect in the Group’s strategy. We are proud of providing glass packaging which is a true part of circular economy.
In order to meet the worldwide and increasing consumption of resources and to take the issue of limited resources into account, Stoelzle provides products made from the permanent material glass for a true Circular Economy and supports the new EU Resource Efficiency Roadmap. We consider the economical use of resources when designing and developing a product (including transport packaging) so that as little raw material and packaging material as possible is consumed and as many material cycles as possible can be closed.
Already for several years Stoelzle has been using in decoration only heavy metal-free colours, which contain absolutely no heavy metals such as cadmium, lead or others. We are strictly refusing to use such products with respect to a better quality of recycling glass.
A maximum of glass recycling saves energy, CO2 and raw materials. For the production of amber glass we can use up to 60% and for green even up to 80% of post-consumer recycled glass and internal cullet.

Emissions along our value chain.
In addition to the circular economy approach, using recycled materials within glass production helps to save energy.
Waste heat utilization and solar panels on the roofs of our Austrian plant are delivering a yearly output (2019) of 22,000 MWh green energy, which is supplied to local electricity and district heating grid.
