Sustainability for a successful future

Over the last few years, the Stoelzle Glass Group has been growing steadily. Linked with this growth and expansion of production capacity, Stoelzle has invested heavily in the field of environmental protection. Today, we can be proud not only of meeting our legal obligations, but also of making a significant contribution to the environment as a result of our ongoing improvements and innovations. Our medium term targets for 2020 and beyond continue to pursue this strategy.

From the inert raw material of glass, we develop, manufacture and market high-quality packaging for the pharmaceutical, food, spirits and cosmetics industries. Thanks to its unlimited recyclability, only glass can claim the capacity to go back into the production process over and over again; to be reused endlessly without compromising on quality, flavour-neutrality or functional safety. This fundamental unique selling point with regard to longevity will be a key aspect in our Group‘s sustainability strategy in the future.
