Sustainability permeates all aspects of our organisation. We apply sustainability in a way that is remarkably versatile: we operate as environmentally friendly as we can and work sustainably to improve the education level, well-being and safety of our staff. By using sustainable methods we demonstrably save energy in the production process. For example, we recuperate the brake energy from the winding machines and use this to drive other machines at the same time. We have also taken measures that demonstrably save energy in terms of the heating, cooling and lighting of all rooms. These measures illustrate how people at ITS think and act in an environmentally aware manner. All this has been formalised since 2010 in a handbook that meets all the requirements of the ISO 14001 system.
