Abstract

Production volumes of organic sludge (digestate) increase as the amount of biogas plants in operation increases and biogas technologies are developed intensively. The rational use of organic sludge is a significant area for improving the efficiency of biogas technologies, since biohumus is an additional valuable product that can be used as organic fertilizer and, accordingly, reduce the cost of biogas production. The more organic material available for decomposition, the higher the biogas yield from the system and the more available organic sludge for plant nutrition. The resulting digestate requires appropriate refinement and quality improvement, primarily its dewatering and removal of harmful substances (including heavy metals). It makes possible to obtain and use an environmentally friendly biohumus as fertilizer for agricultural plants.
