We control operational processes via our integrated management system (IMS). It stipulates uniform standards throughout the Group for issues relating to quality, environmental protection, health and safety. We have our Group management system analyzed by an international certification organization in accordance with uniform standards based on ISO 9001 (quality) and ISO 14001 (environment). In 2011, our Wacker Biotech subsidiary in Jena was included in the Group certification under ISO 14001 (environmental management). All our Siltronic subsidiary’s sites are certified to ISO/TS 16949 and to ISO 14001, due to the company’s specific processes and customer requirements.
