The use of individual biogas plants can be a means of solving many energy-environmental and financial-economic problems. The article aims to assess the prerequisites and consequences of using biogas plants at the macro and micro levels to search for opportunities to reduce the cost of their installation and make them more affordable for individual farms. The need for the use of biogas plants by farms is determined by the fact that these farms have a raw material base; the growing cost of energy resources pushes them to search for new sources of profit. At the micro level, the costs of biogas plants in the conditions of companies and individual farms in the Slovak Republic are evaluated. At the macro level, the aggravation of energy and agricultural problems and the need to transition to green technologies require a comprehensive approach to their solution. The article investigated the cost of purchasing and operating biogas plants based on a private company’s data. It assessed the cost of the construction of a biogas plant and more. The analysis of biogas plant operation results showed that its purchase and use by a farm can be financially unprofitable but bring significant benefits in the energy, environmental, and social dimensions.

“…With reference to the EU standards the treatment of municipal wastewater should be combined with a selected method for utilization of sewage sludge (the end product in a wastewater treatment process) in an environment friendly and economic manner [4], [7], [8]. However, different trends have been observed in other parts of the world.…”

Rational and safe (from the environmental point of view) sludge application is one of the important problems of sludge management. On the other hand, growing number of developed and exploited sewage treatment plants is the main reason for increasing amount of sludge arising. Development of new and effective technology of sewage treatment and more demanding requirements of sewage quality after treatment is also the reason for increasing amount of sludge that need utilization and management. The technologies of sludge dewatering in the scope of currently applied methods and devices were described. Because of increasing requirements to applied process and in the aspects of further management of sludge there is necessity of changes in this field. One of the most important processes of sludge management is dewatering. That is why in the theoretical part the significant factors influencing this process were presented. In the investigative part of this paper the methods of sludge dewatering in the selected wastewater treatment plants (WWTP) were analysed. The selected WWTP were chosen on the base of their throughput and mechanical method of sludge dewatering. The efficiency of centrifugation, belt pressing and bagging system was compared. In each case it was about 80%.
