Thermal waste utilisation plant Dürnrohr, Austria
The waste utilisation plant in Zwentendorf / Dürnrohr was built and is operated by the energy and environmental services company EVN. The energy produced on site is utilised as power, district heat and process heat, thereby replacing fossil energy sources and conserving resources. Dürnrohr is the largest and most modern plant of its kind in Austria.
According to the "waste to energy" principle, the plant has been recycling waste since January 2004. With the commissioning of a third line at the beginning of 2010, the plant's capacity has almost doubled to more than 500,000 tonnes per year. The waste is recycled around the clock, all year round.
In October 2014, with the merger of WTE Wassertechnik, the wastewater treatment sector was also added to the disposal technology repertoire at the plant, where sewage sludge is now also thermally utilised for energy.
The plant meets the required emission limits, it even keeps emissions far below the required levels. Dürnrohr also functions as WTE's and EVN's know-how centre in terms of waste and wastewater disposal. Valuable experience and developments in building and operating the plant are incorporated into new sludge incineration projects to provide for the ecologically and economically best possible utilisation of waste and sewage sludge.
