Vliv technologie kompostování v městské kompostárně na kvalitu produktu

The thesis is about the processing of biological waste in the Czech composting plants with focus on the quality of the final compost. In 2016, there was more than 160 composting plants in the Czech Republic. The thesis is focused on the most widely used technologies in small composting plants in terms of their impact to the quality of the final product, including the follow-up of individual indicators during composting. The best technology in my work is based on a higher decomposition temperature (85 ° C) at the first stage of composting. The practical part of thesis is focused on the measurement of ion-exchange capacity according to Sandhof as a main material for the overall evaluation of the functionality of composting. The final value shows the compost quality of the individual composting plants in terms of ion exchange flexibility of the produced substrate. The best result was achieved with the combination of composting boxes and composting in the belt heaps. The value of the ion-exchange capacity with the best technology was 52.8 mval .100 g of the soil, with 77.9% of the distributed biowaste. You have to expect with an average annual costs of composting about 1,696,000 crounds in the Czech republic, when you are designing small functional composting plant with production of 2000 tons of the compost per year
