The aim of this thesis is the economic evaluation of treatment- and recovery methods of horse urine. This is collected using a newly developed stable floor construction. With this it is possible to collect the horse urine separately from the bedding and then prepare, or use. As the equestrian management in Europe has increased again in recent decades, the exploitation of horse urine can be relevant to agriculture and energy policy. In this master thesis, the preparation of a liquid fertilizer from horse urine is investigated in detail. Practical experiments were carried out using a distillation plant. The horse urine was examined by the water research institute Eawag for its composition, and then samples of the distilled urine were sent to the laboratory of the institute of soil research (IBF) for analysis. It was determined that, after the distillation, a large portion of the nutrients are still present in the primary fertilizer (a brown liquid). Although distillation is a very energy-intensive process, the energy requirement can be reduced to as little as 80 Wh/L. An energy requirement of 107 Wh/L could be achieved in the industrial distillation plants of the aquatic research institute Eawag in Dübendorf, Switzerland. This depends on the size of the distillation plant. By means of literature research and own experiments, it was possible to establish that the horse urine is suitable for use as a fertilizer. The energy consumption can also be kept low by using industrial distillation equipment.
