waste management

The circular economy is a prerequisite for the new industrial revolution, because it contributes to achieving maximum economic efficiency in industry and reducing the negative impact on the environment. Its implementation involves a set of measures aimed at the sustainable development of enterprises, the country and society. Introducing the concept of circular economy is an important and necessary step for the development of our country, its integration into the European Union and post-war recovery.

The issue of segregating plastic waste from the general stream of municipal solid waste and its recycling and disposal is a pressing environmental and socio-economic problem. Given that existing plastic waste recycling facilities in Ukraine are underutilized and partially operate on imported raw materials, the problem of separating and processing certain types of plastic waste from Ukraine's overall solid waste flow is extremely urgent. Plastic wastes are categorized by disposal complexity into three groups:

The evolution and content of the Ukrainian Laws "On Waste", "On Strategic Ecological Valuation", "On Waste Management" as key documents of the national legislative base regarding the treatment and management of waste, including household, on the subject of their ability to provide administration solutions to growing problems in the specified field of activity are investigated.

Purpose. Today, global issues such as population growth, depletion of natural resources, deforestation, greenhouse gas emissions, and climate change show that existing methods of managing the economy are no longer effective and harm the environment. The solution to this problem is the transition to balanced sustainable development, in particular through the circular economy model, which is attracting more and more attention from scientists and practitioners.

The article examines the development of the circular economy in Ukraine, as well as the prospects of implementation of the experience of leading EU countries in the field of circular economy in Ukraine. The relevance of the study is that for now in Ukraine very few steps have been taken towards a circular economy, although everyone understands its importance.

In the conditions of constant deterioration of the environment, municipal solid waste management (MSW) in Ukraine remains one of the most pressing challenges in environmental safety because of its significant accumulation in landfills and the lack of effective mechanisms for its disposal. Approximately 40- 50% of municipal solid waste is organic, so the removal of this part of waste from landfills through composting and conversion of waste into secondary material resources will significantly reduce the environmental load on existing and potentially planned landfills.

The National Strategy and the National Waste Management Plan in Ukraine until 2030, the regional
program for solid waste management in the Ternopil region for 2018-2020 on the reality of conducting key infrastructure measures and achieving the desired result for society are studied. An improved version of the solid waste management scheme in the Ternopil region and a suitable scheme for solid waste management in the city of Ternopil within the regional complexes for the municipal waste recovery are proposed and the sources of their financing are substantiated.

The paper presents the results of a circular economy study and the benefit of implementing this concept in Ukraine, based on the experience of the European Union, and provides recommendations from the Ellen MacArthur Foundation and the European Commission, which should be taken into account by governments in view of the critical environmental situation in the world. Possibilities of formation and development of circular business models in Ukraine on the example of the best European practices in the field of waste management are substantiated.

In the field of waste management, Ukraine is far behind the EU countries, which is, in particular, a consequence of the existing linear model of the economy, and creates significant risks for the environment and the population.

Prediction of cullet accumulation at municipal solid waste landfills was carried out by linear and multiple re-gression methods. Over time, the amount of waste at the landfills will increase and the soil condition will dete-riorate due to Na+ leaching This is confirmed by the experimental study of leaching of sodium ions from the cullet surface of different fractions with pure water and solutions with pH = 4.8 and pH = 9.2.
