Originální abstrakt

The treatment of biosolids / sewage sludge (SS) is one of the most important issues of the wastewater treatment cycle in the European Union as well as in the Czech Republic. Dried SS can be used either for energy production or for agricultural as suitable fertilizer. Thermal transformation of SS, especially application of pyrolysis processing included torrefaction, is typically accompanied by production of pyrolysis oil, pyrolysis gas (syngas) and solid carbonaceous product called either charcoal or biochar, when applied in agriculture or bluegreen infrastructure. The tests included several variables influencing pyrolysis such as mixing SS with additives, pelletization process, pyrolysis residence time, process temperature and parameters such as yield of solid carbonaceous product, yield of pyrolysis oil, yield of pyrolysis gas, content of heavy metals, calorific value, organic carbon, pH, electric conductivity, and surface area. The results indicate that slow microwave pyrolysis/torrefaction transforms sewage sludge into solid carbonaceous product and represents an eco-friendly way of sewage sludge disposal which belongs to the important strategies of circular economy.
