The problems with residents and authorities in the approval process for stables are increasing rapidly. In addition, due to legal changes in various federal states, it is also possible to intervene in existing and approved stables, particularly in the case of neighboring problems. As a result, the authority has the possibility by law to impose subsequent regulations regarding emissions and immissions from agriculture. This creates enormous uncertainty for existing operations and planning uncertainty for future expansions.

There has been decades of research in the field of exhaust air purification, but this technology is currently considered “not state of the art” for economic reasons alone. There is another significant disadvantage associated with the technology of exhaust air purification: it has no effect and does not bring any improvement for the animals themselves and does not reduce emissions in the stables themselves. In addition, it has been proven several times that a reduction in emissions in the animal area, i.e. an improved stable climate, is associated with it with improved animal health and better performance.

The proposed project is intended to investigate which technology, with what costs and with what effect an improvement in the stable is possible, including an impact on animal health and also on the working atmosphere.
