Anaerobic processes have been used in environmental technologies for nearly 150 years. The present paper deals with the use of anaerobic technologies in the Slovak Republic. The introduction briefly describes the past use of anaerobic processes in the world and in Slovakia. The conditions of anaerobic wastewater treatment and stabilization of sewage sludge in biogas plants and biogas production in landfills are discussed. Anaerobic sludge stabilization with biogas production can be found at 52 wastewater treatment plants (WWTPs), of which 22 have cogeneration units with the electrical output of 5.14 MW installed. Only one anaerobic industrial WWTP has a cogeneration installed, with the electrical output of 0.32 kW. Total installed electrical power of 111 biogas plants is 103 MW and the total installed electrical power of ten landfills is 2.24 MW. In the conclusion, further possibilities of the development of anaerobic technologies in Slovakia are presented.
