Objective: Determination of optimal ways of sludge sludge treatment of wastewater treatment plants on example of several cities in Ukraine. Development and analysis of project proposals for disposal of freshly formed sediments. Sewage sludge utilization technologies must meet two requirements - use of energy potential and absence of negative environmental impact on products of their recycling. New technologies for disposal of sediments that meet these requirements are being developed: pyrolysis, hydro pyrolysis, combined processes of fermentation and gasification, polygeneration, steam conversion, gasification of mixtures with other fuels, thermocatalytic reforming, three-stage gasification. Most of these technologies have not yet been commercialized. Energy potential of "fresh" sediments in Ukraine is estimated at 446 thousand tons of conventional fuel. Its use for production of electric and thermal energy and secondary liquid and solid fuels is appropriate as being consistent with global trend of decentralized energy development. Economically efficient, acceptable for Ukrainian conditions is the technology used to dispose of sediment, is their joint combustion with other solid fuels and waste in boilers of TPPs and cement kilns. For objects of decentralized energy, it should be preferred to processes of gasification or pyrolysis of ERUs. Composting technology is acceptable to dispose of accumulated precipitates.
