Greater local heat:
Wastewater waste heat for Jena-North
The industrial estates along Wiesenstrasse in Jena-Nord are expected to be supplied with CO2-neutral heat from 2030 via a new local heating network. Wastewater heat pumps at the central sewage treatment plant will be used to recover the heat from the treated wastewater. The use of wastewater heat is both ecologically and economically highly efficient. This is because it is permanently available at the central wastewater treatment plant and can be used all year round via heat pumps. By tapping into this considerable heat potential, we are taking a further step towards the heat transition and climate neutrality for Jena.
