Abstract

In new conditions of the energy system functioning in Republic of Belarus, biogas plants should be reoriented to the production of mainly heat energy for local purposes and production of biohumus – organic fertilizer from methane fermentation sludge. From the point of view of biohumus production, the main problem is the low content of dry matter in digestate (usually not more than 8%) and, accordingly, water content – up to 90-92%. The main methods to refine are its dewatering and thickening. The processing of organic sludge allows to reduce the volume of waste storage, improve the quality of environment, obtain an additional product with added value, which can be used as a valuable organic fertilizer. Rational use of organic sludge is a significant area of ​ ​ increasing the efficiency of biogas technologies.
