The conditions at this project location in contrast are almost ideal. Normally, composting is carried out directly in the sheds by covering heaps of dung with straw and then pushing them to the side every day. Flies and insects in the sheds are quite common. The farmers are interested in a solution to this problem. A dairy cattle programme introduced by a private cooperative which attaches great importance to hygiene in the sheds makes it clear for the farmers that the compost heap in the shed can be an economic disadvantage. Organic fertilisation is a tradition and is carried out carefully. When a biogas plant is built, dung and urine are pushed into the biogas plant or collected outside the shed. The slurry overflowing, either flows directly onto the fodder fields or is processed into compost which can be transported. The composting of slurry only means little adjustment for the farmers. These favourable conditions are enhanced by a healthy economic situation of the farmers. The counterpart organisation also has expert competence and good access to the target groups. Highly qualified craftsmen also make it easier to establish know-how for building. However, future financing of the biogas programme is still uncertain. The task for the project here is to establish biogas technology also financially on a state level.
