We consider every direction

With its core business of wear protection, Kalenborn has been helping its customers to operate sustainably for over 100 years. With its solutions for protection against wear, Kalenborn secures the flow of material and prevents its customers‘ production from premature downtimes.

Special processes for the protective lining of plants and pipes enable them to be reused instead of having to be produced anew. This saves considerable CO2 emissions and protects the environment.

We use photovoltaics as light energy for our own electricity generation and heat recovery in our production furnaces for the manufacture of our materials. With basalt and ceramics, we rely on natural materials that are regenerable.

Kalenborn report on its key sustainability issues

With the new Corporate Sustainability Reporting Directive (CSRD), the EU will in future oblige companies to report on sustainability in their annual reports. A sustainability report informs about the sustainability of the company’s own decisions and what impact they have had on the environment.

The German Sustainability Code (DNK) is an instrument that helps Kalenborn to systematically record and transparently present its sustainability activities. The analysis resulted in the following materiality matrix for Kalenborn. It shows on the Y-axis the impact of Kalenborn’s sustainable issues on the environment and society and on the X-axis the financial impact on Kalenborn as a company.

The following topic areas are important for Kalenborn, to which the sustainability themes are assigned in color:

  • Environment: Climate protection & resource efficiency
  • Employer responsibility
  • Governances, Processes & Economic efficiency
  • Social responsibility and transparency


The higher the materiality of a topic, the more relevant the sustainability efforts are for reporting purposes.
