We are proud to protect resources and the environment.
We are convinced that companies must act and manage their resources responsibly to prevail in the future. That’s why we aim to manufacture our products with minimal resources and optimized energy input to avoid unnecessary environmental burdens. We use as many regional resources and materials as possible to manufacture our products. We continuously strive to achieve an integrated and sustainable life-cycle assessment for all of our processes and products.


We have implemented an environmental management system certified according to ISO 14001 to ensure a sustainable corporate concept with consistent product quality. In addition, TÜV Rheinland audits our environmental protection and sustainable production measures every year.
Our detailed analysis of all raw materials associated with production aims to avoid contaminants from the onset and to use recyclable materials wherever possible. We rely on regional raw materials (particularly quartz sand, a key ingredient) and recycled glass from our own production to guarantee short transport paths. We also give preference to regional energy sources for our production plants.
We are committed to continued process innovation to minimise our energy use in glass melting. A closed cooling water circuit, heat recovery technology, filter systems as well as UV and laser technologies reduce our energy consumption and make sure that water is returned to the environment in clean condition.
We are particularly proud of our oxyfuel technology, which significantly reduces our carbon dioxide and nitrogen oxide emissions. This technology enables us to use 30% less energy in production compared to conventional gas-heated glass melting furnaces.

Tritan® crystal glasses not only are brilliant, break resistant and dishwasher safe, but also stand out for their sustainability. Our consistent selection of low-emission, recyclable raw materials for production makes our products especially durable and environmentally friendly. Approx. 50% of each individual glass consists of recycled Tritan® crystal glass.
Based on our detailed analysis of all raw materials, we can produce high-quality glasses that are 100% food-safe and 100% BPA-free.

Our packaging is mostly FSC® (Forest Stewardship Council) certified and marked with the green dot to show it is made from environmentally friendly, recyclable materials. Our filling pellets are biodegradable as well. Boxes can be reused, e.g. for storage or moving. Thanks to the unique design, the product boxes also make ideal gift packaging to give your loved ones a special treat.
