Why KrunerClay

Sustainable, environmentally responsible

No need for kiln firing

With our revolutionary binding technology, KrunerClay can be chemically hardened into superior clay products without kiln firing.

Cost-effective. High efficiency. Pollution-free.

Without kiln firing, KrunerClay plants are more efficient and cost effective, using 50%–60% less energy. They also release less pollutants with 70%–90% reduction in CO2 emission, without industrial byproduct wastes such as fly ash from burnt coal.

100% natural, harm-free binder

Our proprietary binder uses 100% natural and harm-free raw materials that are widely accessible and responsibly mined.
