At the end of the 1980s, the state of Baden-Württemberg organised a nationwide practice test on energy production and utilisation. Under this practice test, energy forests of poplars and willows were planted on land previously used for agricultural purposes. The produced biomass is to be used as environmentally-friendly energy for combustion in heating systems. Preferably, the energy generation should take place within a network system near the production site.
The correctional facility Ravensurg, branch ‘Bettenreute’, implemented this test for their own energy supply. The four working areas – crop management, animal husbandry, fuel wood production and packaging operations – were set up to provide optimal opportunities to rehabilitate the prisoners. In this context, there is a 5.5 hectare area where fastgrowing tree species (poplars) are cultivated. The acreage is only a few hundred meters away from the wood chip heating system, which is housed in a purpose-built building, also containing the bearings for the chips. The stock for a year can be stored in this building. The prisoners are obliged to work. They are involved in the establishment of the fuel wood plantation and take care of the plants (weed control). The prisoners harvest the trees with a chainsaw and place the logs into the wood chipper. Thus, heat is produced for the accommodation of the prisoners and for the administration building at the agricultural branch of the correctional facility, Ravensburg.
The goal is to produce the complete heat supply of the agricultural branch ‘Bettenreute’ by the energy forest. The most significant innovation is the production of energy wood in a previously agricultural area. The fact that prisoners will generate energy through the use of the fuel wood plantation not only achieves ecological objectives, but also social ones.
