Landfilling of municipal solid waste generates a number of problems. This article focuses on one of them – the settling of the landfill surface due to organic residue biodegradation.
This article presents the results of experimental studies investigating the energy consumption per 1 kg H2O required for the filtration drying of beet pulp. The optimal process parameters for the removal of 1 kg of moisture from the dried beet pulp were determined, which included the height of the layer of dried material H=120 mm, the thermal agent temperature T = 90 °C and the thermal agent velocity v0 = 1.76 m/s. Regarding these parameters, the total energy consumption for drying by the filtration method from the initial moisture content of 88.12 % wt.
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 article is devoted to the study of the current state and prospects of implementation into national legislation of the normative provisions of the European Union in the field of waste management, in particular the Directive of the European Parliament and the Council «On packaging and packaging waste» (1994, December 20) № 94/62/EU.
Implementation and compliance with European environmental standards is a significant factor in ensuring the implementation of the provisions of the Association Agreement with the EU. Among the environmental problems that pose threats to national security are the processes of generating significant volumes of production and consumption waste, the insufficiently effective level of their reuse, recycling and disposal.

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.
