As a hobby and leisure partner, the horse has become an indispensable part of our society. A horse produces up to 50 kg of manure per day. With approx. 1.2 million horses in Germany alone, this is an enormous amount. Not only the animal itself but also its dung has become an economic factor. Especially when it comes to the energetic utilization of residual materials, the biogas plant is once again coming into focus. Biogas is produced by the fermentation of stackable manure from animal husbandry and other organic waste, which is converted into electricity and heat during the combustion process in a combined heat and power plant. Horse manure, which is mainly produced in rough quantities in larger operations and cannot be optimally utilized in conventional liquid biogas plants, causes disposal costs.
With approximately 1.2 million horses in Germany, slightly more than 10 times as much horse manure is produced each year. This enormous potential is currently not yet being used to generate energy. In addition to the energy, organic fertilizer with good plant availability is produced.
