| Abstract: |
The decreasing dependence of electric energy generation on fossil resources and the need of efficient storage and handling of resources for its production lead to the ever‐increasing support of biogas. Systems of using renewable energy sources (RES) depend on the production of plant biomass whose yields may be impaired by the climate change, namely by fluctuating temperatures and unevenly distributed rainfalls in the growing period. This study brings an analysis of the composition of elements and nutrient contents in sugar beet tops and their parts in order to find out whether the sugar beet tops can be used as a substrate suitable for methane production in biogas plants (BP). Based on the obtained results, a theoretical methane yield (TMY) was calculated using three different methods. TMY calculated using a stoichiometric equation ranged from 287 L/kgVS (crown without leaves) to 354 L/kgVS (leaves), which is comparable with the methane yield mentioned in the literature for maize. Comparing different methods of the calculation of TMY from sugar beet tops, it was found out that TMY determined by means of stoichiometric equation based on the contents of C, O, H, S and N might be less accurate in the case of sugar beet. More accurate TMY estimates can be achieved by using TMY calculation methods based on the content of simple carbohydrates, proteins and lipids in sugar beet tops or methods with the calculation based on a partial elimination of the part of organic matter with a low rate of biodegradability. TMY calculations have to take into consideration the share of leaves and tuber crowns in the biomass of fresh beet tops as there are great differences in their biodegradability, which might lead to inaccurate results.
