Steinzeug-Keramo has had its products and production processes certified. The Cradle to Cradle certified® Bronce certificate documents our commitment to the environment and is a confirmation of our sustainability-oriented product philosophy.

With standard production processes, materials often end up "dead" – i.e. in the dustbin or in an incinerator. Limited natural resources are irrevocably lost in the process. The environment is heavily burdened and future generations have to pay the price. For a long time, people have sought to make improvements within this system. But, despite recycling and waste reduction, it remains a system that only thinks as far as the dustbin, and is willing to accept garbage and waste.

But it doesn't have to be that way. In the Cradle to Cradle Certified® system, products circulate in a continuous cycle of materials.


Cradle to Cradle Certified® means that everything is planned from the start to ensure that nothing ends up as garbage. Each component continues its service, becoming a raw material for another new product in a system that profits industry, the economy and consumers alike.

At the same time, the Cradle to Cradle® principle itself has been copied from nature. Every years, a tree produces thousands of flowers and leaves. When they fall to the ground, they continue to offer numerous benefits. Over time, they are decomposed by microorganisms, animals and weather, releasing new nourishment in the process – for the tree itself, and for other plants as well. 

A product solution with many strengths

A long service life together with low maintenance and repair costs makes them a long-term, economically viable alternative.

Ceramics are 100% recyclable and turned into grog for the production of vitrified clay pipes.

The Cradle to Cradle Certified® five column principle

No part is untested. We know the exact composition, service life and environmental impact of every item.
Our materials are ecologically sound.

We are committed to water stewardship and treat this resource with great care, consistently adhering to the  Cradle-to-Cradle® principles.
 Our production sites are located only in water-rich areas.

All the pipes we manufacture are recyclable, but can also remain in the ground. Sustainability, in our opinion, means a perspective over centuries.

We are constantly optimising our energy consumption: We use fast-firing technology. Heat recovery via additionally installed heat exchangers. Energy from a regional biogas plant.

 We see our employees as responsible people and we make every efort to support them in this role. Work safety, a work-life balance, skill enhancements and career planning are core policies.
