The material is completely recyclable. cardamia – econic clay consists of clay. Unlike mining other raw materials, clay mining does not destroy nature. It is also produced sustainably as unburned clay, therefore saving energy. The light weight makes it easy to transport – and saves energy, again, in transportation. At the same time, cardamia is produced under fair working conditions. Integrated into a room, it generates a healthy and pleasant indoor climate. This is futher illustrated by the Blauer Engel, CE, and TÜV certifications.
