Working with innovative materials has always been part of HERING Systeme’s expertise. With clay as a building material, however, we are taking a decisive step toward sustainable and resource-efficient construction. Clay is regionally available in large quantities, approved for use in many applications, and stands out due to its outstanding ecological performance.
As part of the DBU-funded development project “LeNaKo – Recyclable Clay-Natural Fiber Composites for the Industrial Production of Cast Prefabricated Clay Components”, we are developing a specialized clay formulation for industrial manufacturing. Regional clays and aggregates are optimally combined with natural fibers and bio-based additives. Initial test results are highly promising.
Our development team is supported by the Institute of Building Materials Research and the Institute for Textile Technology at RWTH Aachen University, providing scientific expertise in clay material and fiber development.
A New Approach to Industrial Clay Components
Modern clay construction typically uses clay bricks or rammed earth techniques. In some cases, materials are modified in ways that limit recyclability.
Our project goal is to manufacture clay components using the casting technology of a conventional precast concrete plant – enabling precise, industrial, and scalable production.
A key focus is full recyclability:
We deliberately avoid chemical additives that would reduce reuse potential. The result is a circular building product combining sustainability with industrial efficiency – a genuine innovation.
Demonstrator Planned for Mid-2026
In mid-2026, we plan to present a demonstrator on our production site. The first industrially manufactured clay components will be available for hands-on experience. Long-term performance and weather resistance will then be monitored under real conditions.
With LeNaKo, HERING contributes actively to the advancement of sustainable construction materials and rethinks industrial production.
