CSR Birgit S. We protect what really matters – our employees and the environment, underlines Birgit, the Stoelzle CSR Manager. “It is my duty to coordinate and guarantee the implementation of CSR-relevant ISO standards in all sites of the Stoelzle Glass Group. Ethically and socially correct behavior means as much to me as energy and environmental management. As CSR Manager of the Stoelzle Glass Group, I am particularly proud of our glass products, which are 100% and infinitely recyclable and thus become a true part of modern circular economy!"
