In the Gmunden cement plant, a system of innovative heat exchangers has been used since the beginning of September 2019 to decouple excess waste heat from the clinker burning process and make it available to the regional district heating network.
Since September 2020, the Gmunden hospital has also been supplied with heat from the cement works as a bulk buyer, which means that more than twice as much waste heat can be sensibly used than a year ago. This is based on heat extraction, which uses excess energy to heat water to around 95°C. This can be used for heating via the district heating network of Energie AG. Overall, the available energy would be sufficient for around 550 households.
In 2019, this development was honoured with the Global Energy Award.
