Biodegradable agricultural wastes such as manure, has long been used as an organic fertilizer that improves soil structure, enriches the soil with micro-organisms and micro-elements necessary for plants and promotes humus formation. Manure can also be successfully used as a renewable energy source directly combusting and extracting energy. The carried out investigation showed that the incineration of manure remaining in ashes could also be used as a fertilizer. Waste combustion reduces its volume to 80–90%. Also, the investigation revealed that the amount of chemical elements (Na, Mg, Si, P, K, Ca, Ti, Mn, Fe) decreased after combustion. However, the concentration of these elements in ashes is higher than that in raw manure.
