Purpose. The article describes aspects of the environmental impact of municipal solid waste (MSW). Purpose of the paper is analysis of environmental problems, which are created by MSW, ways of solution and modern state of MSW recycling in developed countries and Ukraine. Methodology. We have applied the analysis of the current situation with municipal solid waste management by means of literary sources, statistical data and evaluation of the extent of threats. Results. Annual waste volume growth has set a problem of recycling and reusing for humanity. Traditional methods of disposal of municipal solid waste are storage in landfill and incineration. But waste disposal is environmentally unacceptable. This method forms epidemiological and biological hazards; garbage can catch fire themselves and emit the harmful products of combustion. Simultaneously aquifers are polluted by leachate. Incineration in plants reduces the volume of waste and its danger, but this process forms even more harmful emission. Therefore, such technologies require extremely effective systems of the flue gases cleaning, and they have cost about of 40% of the worth of the enterprise. One of the most promising technologies of MSW recycle is pyrolysis, it allows getting combustible materials, but because of the huge cost of the technology, its using is still very limited.
All modern waste treatment technologies are based on prevention (preparing for) reuse and further recycling. The developed countries have recycled nearly 90% of the waste. In Ukraine, more than 90% of waste is taken out to dumps and landfills. Ukraine needs to improve the system of waste management. Originality. We have carried out the integrated analysis of the situation with MSW. We have offered possible solutions to the MSW problem in Ukraine. Practical value. We have determined the bulk of municipal solid waste has being taken to landfills. It is the main source of environmental problems across our country. If in the nearest future reliable recycling program will not be created, Ukraine can become an area of environmental disaster. References 10, figures 1.
