We show responsibility for people and the environment

We firmly believe that our success lies not only in the quality of our products, but also in our contribution to greater sustainability, healthcare, satisfied employees and fairness.

Environmental protection and sustainability

Our company is characterized by a high level of innovation – not only in the technical field, but also in terms of sustainability and environmental protection. This is a key concern for us, especially as the production of technical ceramics is an energy-intensive process. We are therefore always committed to economically feasible environmental protection measures. Since 2005 we are certified by the environmental management standard DIN EN ISO 14001 and, since 2012, in accordance with the energy management standard DIN EN ISO 50001. Through continuous improvement and innovation, we are working together to minimize our ecological footprint and shape a green future. At Sembach sustainability is not a target, but a daily journey on which we make progress.

Our certificates

Health protection and occupational safety

Protecting health in the workplace is a top priority for Sembach. This includes not only accident prevention and plant safety measures, but also comprehensive prevention to maintain the physical and mental health of the workforce. OHSAS 18001 / ISO 45001 certification underlines the company’s commitment to a safe and healthy workplace. Sembach sees it as his responsibility to create a working environment in which all employees feel comfortable and protected.

We attach great importance to a culture in which team spirit is not just an empty phrase, but is lived and revitalized every day. We are also aware of our responsibility towards our employees. Because motivated and satisfied employees are our most important asset. This is why we continuously invest in the further development of our employees and their working conditions in order to meet the requirements of a modern and safe working environment.

Compliance and Code of Conduct

With and for people is the motto under which we are committed to responsibility, ethics and fairness in every aspect of our business. Our established Code of Conduct is the guideline for our common endeavors and forms the basis for fair and respectful interaction with one another. Our information security guidelines guarantee the highest level of data protection. We are firmly opposed to all forms of discrimination, while respecting and promoting human rights.
