Since the turn of the millennium, VEKS’ environmental work has been subject to approval by the EMAS directive, and the company’s environmental management has been certified in accordance with ISO 14001. In practice this means that environmental tasks have been systematised, documented and adhere to a consolidated matrix and concept. For instance, this applies to mapping of environmental impact, action plans and project/procedure descriptions. The environmental projects are carried out by VEKS employees who have all participated in internal training in environmental aspects. Many environmental initiatives often turn out to have a positive financial rub-off effect. VEKS’ environmental work is audited and approved annually by an external, certified consultant. Throughout a number of years, VEKS has participated in numerous research and development projects at home and abroad. The primary goals related to these projects are resource savings, streamlining and environmental considerations. Most often, VEKS will participate in cooperation with other businesses and educational institutions. Finally, VEKS acts as the host of many national and international guests who show an interest in the company’s operational issues, preventive maintenance, tariff structure, organisational issues, etc.

Technical facts and facilities
The transmission system consists of a supply line with maximum 115 ºC hot water and a return line, in which the temperature is approximately 55 ºC. In brief, the local district heating companies receive their heat from VEKS’ supply line via a heat exchanger, following which they circulate the hot water to the users. VEKS them transmits the cooled water back to the heat producers, ie Avedøreværket and the waste incineration facilities, in order for the water to be reheated. In order to secure system functioning and lifetime, all the pre-insulated steel pipes with plastic casing immersed into the ground in a drained layer of soil. Alarm wire sensors have also been immersed into the insulation material to detect any formation of moist. Most exchanger and pumping stations are located under ground and are also provided with alarm equipment to prevent a major breakdown, accidents and damage.
