TECHNOLOGICAL ASPECTS OF ENERGY USE OF SOLID HOUSEHOLD WASTE

Abstract

Technological aspects of energy use of solid waste and their constituents and possibility of applying certain technologies in Ukraine are analyzed. Global trends in waste management technologies are identified. When organizing waste sorting, half of their energy potential can be used, which is estimated to be 1.5 billion m3 of natural gas equivalent in Ukraine. Share of food waste is close to 40 %. It is advisable to recycle them in biogas and biomethane mixtures with agricultural waste and energy plants. Biomethane production can be increased in several times. Electricity and heat production from biogas require government assistance in form of special tariffs. Biomethane is being used alongside natural gas in compressed and liquefied state as a motor fuel. Biogas complexes are used as balancing power of grids. The most common technology for utilizing the energy potential of municipal solid waste is incineration. Emissions systems for waste incineration plants have reached a level of perfection that allows them to be placed close to residential areas. Ref. 15, Fig. 6, Tab. 2.
