On May 11, representatives of the Bioenergy Association of Ukraine, as part of a large group of environmentalists working on improving the solid household waste management system, visited the municipal solid waste (MSW) landfill №5 near to the Pidhirtsi village.
MSW Landfill №5 is the largest storage facility for municipal solid waste in Ukraine. This is an engineering building with an area of 65 hectares, built in 1986. For 33 years 15 million tons of solid waste or about 10 tons of waste for one Kyiv citizen have been accumulated there.
MSW Landfill №5 has a lot of similarity with the sanitary polygons of developed countries:
- use of Heavy machinery (compactors) for effective sealing the waste layer (Fig. 2)
- covering part of the waste with a temporary layer of soil (seen in the background in Fig. 3)
- flandfill gas collection for power generation (Fig. 4)
- prevention of contaminated water (filtrate) (Fig. 4) enters the underground horizons, including cleaning this water in installations (Fig. 5). The quantity of such installations is planning to be increased.
- fencing dams (Fig. 6) which are constantly strengthening – placed along the perimeter of the test site.
- weight control of MSW at the landfill entrance (Fig. 3)
The listed measures allow reducing the negative waste impacts on the environment.

On the other hand, the landfill is largely exhausted its project capacity and in the coming years, it should be closed.
In Kyiv, and in general in Ukraine, a solution to the problem of waste management is urgently needed.
An alternative to landfill burial of the generated waste is sorting and separation, as well as the processing of the sorted waste residue by the mechanical-biological or thermal method. Waste processing does not eliminate, but significantly reduces the amount of landfill MSW.
Unfortunately, the existing tariff – UAH 205/t – is enough to place MSW at the landfill, but not enough for its processing.More about the problem of recycling the municipal solid waste can be found in the UABio position papers (2019) here.
