Workshop outputs

In the first part, Dr. Georg Kasberger (director of forestry of the administrative office for agriculture and forestry) gave an overview of the present situation of wood production and use in the district of Rosenheim. It was pointed out, that there is still a huge potential in use of wood to cover the heating demand. The overall potential of wood as an energy source for heating can be seen by 30% of the total heating demand for households. In total, the annual wood production for the heating sector is equivalent to 45 million liters of fuel oil. According to Mr. Kasberger, all of the 33% of land that is covered with forests is cultivated in a sustainable way (e.g. PEFC certificate). In the second part, Mr. Sebastian Henghuber, chairperson of the MW Biomasse AG explained the overall potentials of wood chips as energy source, especially by using district heating networks. The MW Biomasse AG is an association of forest owners and farmers which operates more than 15 district heating networks in the district of Rosenheim. Mr. Henghuber made clear that a new EU directive that is being discussed in the moment, could shoot down all the advantages of wood as energy source. According to Mr. Henghuber, the use of wood chips in district heating networks could be seen as the future for small communities with a heating demand of up to 2 MW power. Mr. Johann Bauer, the 2nd mayor of Vogtareuth concluded the workshop by introducing the project of the community of Vogtareuth, where in 2010 a new woodchip heating plant was installed. This heating plant covers the heating demand of the primary school, the kindergarten, the town hall and the fire station. The total heating power is 300kW which is covered by two 150kW heating plants. In the case of Vogtareuth the project was funded by the state of Bavaria. According to Mr. Bauer, the project could not have been financed without that funding due to the very homogeneous use of heat (e.g. all the connected building don’t need domestic hot water in the summer).
