Our four key messages to quality are:

The environmental, health and safety policy is a practiced and self-imposed obligation for ZSI and is supposed to help secure the natural foundations of life.

The reputation, the success and the trust of customers, shareholders, employees and business partners depend decisirely on the concrete behaviour of every single employee. To clarify the responsibilities, a behaviour guideline was created including minimum standards, which is mandatary for our employees. It should help to overcome the legal and ethical challenges in daily work, should provide orientation and strengthen confidence in the performance and integrity of the ZSI furthermore.
