Energy Globe Upper Austria Award for energy from wastewater

Austria's best environmental projects were honored at the Energy Globe Austria finale at the beginning of October. The Rabmer Group received the medal of honor in the water category for "Energy from wastewater for renewable heating and cooling of buildings". The innovative technology was the winner in Upper Austria.

A total of around 300 Austrian environmental projects were submitted for the Energy Globe Austria this year. The winners in the categories Earth, Fire, Water, Air, Sustainable Community and Youth were chosen at an online ceremony on October 7. The Rabmer Group was awarded a medal of honor in the Water category for "Energy from wastewater for renewable heating and cooling of buildings".

Upper Austrian provincial victory in the water category
Before the big Energy Globe Austria final, projects at state level had already been awarded the popular trophy: Rabmer was able to secure first place in Upper Austria in the water category with energy generation from waste water.

About the "Energy from wastewater" technology
The previously largely unused waste water is available all year round as a renewable energy source. The temperature is constantly between 12 and 18 degrees. If there is a business nearby, the temperature of the wastewater can rise to up to 30 degrees. Wastewater can be used to heat or cool buildings. Heat exchangers extract heat or cold from the wastewater and heat pumps then bring the energy source to the required temperature level. Around 14% of the heating and cooling requirements in the building sector can be covered by renewable wastewater energy from sewers upstream of the wastewater treatment plant. In addition, further heating and cooling is available directly at the wastewater treatment plants, so that a total of around 25% of the entire building sector could be supplied with energy from wastewater. The Rabmer Group develops individual and innovative solutions according to project requirements. This makes a significant contribution to the energy transition and climate protection.
