Title: Waste Water Energy in Weiz
Even used waste water affords opportunities for helping the environment. In a cooperative project with the city of Weiz, the PW power company of Styria established one of the largest waste water treatment plants in Europe. Heat exchangers extract heat from the cleansed waste water to heat and cool the plant. The project strived for optimized environmentally friendly energy generation. The energy from waste water can save 150 tons of CO2 emissions annually.
