BlueKolding has a clear-cut purpose: Imagine a world without waste. Powered By You 2.0 utilises surplus heat in wastewater for district heating. The wastewater from the 83 apartments in a student residence flows into a heat exchanger along with wastewater from other households, heating the district heating water, which is then pumped into the radiators of the apartments via a closed circuit. Thus, thermal energy from wastewater accounts for 100% of the entire building’s heat consumption.
Statement of the jury
The idea of using wastewater from the shower as heat for the heating system rather than draining it into the sewer is brilliant. A sustainable system that saves resources and lowers costs.
