The aim of the thesis is to verify and experimentally prove that there is technically possible and economically, energetically and environmentally rational to produce solid fuel from biodegradable waste with parameters of solid alternative fuel according to planned legislation and to design equipment for such production. This research is carried out through literary research of similar solutions and past research and scientific publications, own experimental work and design of the technology. The experimental determination of the thermal performance of aerobic fermentation processes for subsequent utilization in biomass bio drying, the analysis of dependence of energy properties of the material on the input material composition, the theoretical demonstration of feasibility of the biomass bio drying technology without additional heat source and the design of the technology that would experimentally and theoretically described phenomena introduce into industrial practice.
