Due to the vertical range of manufacture of the Group, purchasing is of great importance.
In addition to purchasing organized locally, there is a central Group purchase department which is operated together with the sister company, Christ Water Technology, and thus can use economies of scale.
In 2006, a code of conduct was established across the Group, which employees and suppliers are subject to, together with the strict rules on conditions for purchasing, which stipulate extensive regulations relating to working conditions and social standards (referring to SA 8000) as well as a ban on corruption. Suppliers are subject to regular assessment which is based on sustainable partnership and dialog.
