    Improvement of the municipal solid waste disposal system in Ukraine, on the example of the town of Chortkiv, Ternopil region

    Today, in Ukraine, there is a problem with solid waste disposal, especially in small towns. The lack of a developed system for the collection and disposal of solid waste, the presence of natural landfills instead of equipped landfills lead to the fact that small towns are abandoned. Therefore, the creation of a new solid waste management policy is an acute problem for these towns and villages. This article is devoted to analysing the global experience of solid waste management and, based on that, formulating recommendations for solid waste management in small towns using Chortkiv as an example.

    Waste (tailings) of mining and processing plants of Kryvbas were studied by the stages of their magnetic enrichment. The granulometric compositions of the tailings, the amount of iron (total and magnetic) and the mass fraction of solid in them are determined. The expediency of disposing of ferruginous quartzite waste at the first stage of enrichment as a silica component in cellular concretes is proved. Optimal compositions of aerated concrete mixtures are determined based on the following criteria: the average density of cellular concrete in the dry state and its compressive strength.
