Waste issue of Vienna appr. 1 million t of rural wastes produced appr. 36% of which are seperately collected and recycled or composted additionally 2 million m³ of sewage sludge Vienna has a total incineration policy:-> all non-recyclable wastes are incinerated-> all dewatered sewage sludge is incinerated

  4. Thermal wastetreatment in Vienna

  5. Waste to Energy electricity Waste/Sludge Incineration Power Plant Directheating 95% Waste Energy 5% 28% 67% 1,200 km of district heating and cooling network

  6. Districtheating in Vienna saves CO2emissions! 2/3 of CO2 emissions saved yearly 1 million t CO2 emissions saved this is equivalent with- yearly emission of 750,000 cars- yearly emission of 250,000 houses District heating in Vienna actively protects our environment!

  7. Future perspectives expansion of district cooling new buildings are mostly connected to district heating expansion of tubing network renewable energy sources (e.g. biomass) geothermial plant for 40,000 households
