Stadtwerke Gießen invites you to an open day at one of its thermal waste treatment and energy utilisation plants.
On Sunday, 15 September 2024, Stadtwerke Gießen (SWG) will be opening the doors of the Thermal Residue Treatment and Energy Recovery Plant I, or TREA I for short, to interested visitors from 11 a.m. to 5 p.m. The plant in Leihgesterner Weg has been producing heating energy for the Giessen district heating network since 2010. SWG experts explain how the necessary processes take place during informative tours of the plant. They explain all the important details and answer any questions that arise during the tour. In addition, the SWG stand awaits visitors with lots of information about district heating and entertaining games. Of course, SWG will provide food and drinks at family-friendly prices.
Similar to your own boiler room
Just like the heating in your own home, TREA I heats water in its
water in its boiler system, which is fed into a circuit. However, the fuel used is neither natural gas nor heating oil, but processed waste from commercial operations. This has a decisive advantage: "With the commissioning of TREA I around 14 years ago, we have significantly reduced our dependence on fossil fuels for the heat supply in Giessen," says Matthias Fink, Head of the Heat Supply Department at SWG. In addition, the alternative energy source offers another important advantage: it does not have to be transported to Giessen from far away, as it comes from Central Hessen. Every year, up to 53,670 tonnes of energy-rich waste from various processing plants can be supplied to TREA I and its modern sister plant TREA II. Up to 50 per cent of this consists of wood, cardboard, paper or cellulose. In an average year, TREA I covers the heating requirements of around 3,300 single-family homes.
