The cleenTEC® seal serves as an orientation aid. It identifies products with which customers can opt for our high quality, but also for greater environmental protection. The term “cleen” is made up of the words clean and green and is thus intended to encompass all aspects of sustainability. All products with this seal have been manufactured in climate-neutral production facilities and also contain other environmentally friendly innovations. For example, they contain recycled materials, are particularly easy to recycle, are produced with fossil-free raw materials or are themselves completely climate-neutral.
