When developing and introducing new manufacturing processes, we take the associated environmental impact into account at an early stage. We prefer to use materials and supplies that are less harmful to the environment.

In addition to compliance with the relevant environmental legislation, we are committed to continuous improvement in environmental protection and energy-related performance as well as avoidance of environmental pollution.

Hoffmann + Krippner regularly monitors and evaluates the environmental impact. From this we derive goals and measures, the implementation of which we consistently pursue.
