he main aim of the given research is to analyse Government policy early response due to the Covid-19 crisis in Central and Eastern Europe regarding SME support. The research methodology is based on an analysis of the pandemic impact on key indicators of countries development as well as an analysis of SME support policies responses by selected countries (Bulgaria, Czech Republic, Hungary, Poland, Romania, Slovenia and Ukraine). The dynamic trends of Covid-19 spread and its impact on macroeconomic indicators were analysed. The negative growth of GDP, as well as current account balance and increasing gross debt burden, were explored in all analysed countries and the policy responses were the required measures to avoid possible economic collapse. Implemented measures were mainly directed to achieve economic recovery and capturing stability, but the main focus of the research is to analyse the support policies according to the criterion of enterprise size, SME in particular. The study is based on country-level data as well as on individual State Aid cases of each analysed CEE country. It allowed to evaluate policy response mechanisms in terms of measures regarding enterprise size. Although SMEs suffered the most during the crisis, CEE countries spent most of their resources on supporting companies, regardless of their size.

Circular economy offers opportunities to boost jobs and tackle climate change. The article reflects aspects of the impact on the environment through sectoral policies to support the circular economy because current business as usual model, based on the linear economy principle leads to a staggering inefficiency in nature resources are managed, with increased pollution, loss of ecosystems and substantial losses of value with each product disposed. This requires a change not only in consumer behaviour but even more on the resource extraction and material production side. The purpose of the research paper is to develop a decision-making matrix providing a step-by-step approach for the policymakers.

In today's fast-developing world, the use of composite materials is closely related to environmental pollution, renewable and biodegradable resources. A researcher is looking for environmentally friendly materials. Natural and synthetic fibres come in a wide range of shapes and sizes. Natural fibres include jute, straw wheat, rice husk banana fibre, pineapple leaf fibre, cotton, Sisal, Coir, Oats, and Bagasse. Every year, 13.5 tonnes of banana fibre are produced in India. Teabags, paper, and polymer composite reinforcement are just a few of the applications for banana fibre. This article focuses on the manufacture of banana fibre with epoxy and a variety of other natural fibres. By combining banana fibre with some current technology, waste will be reduced, and energy efficiency will be increased, all while supporting sustainability. Banana fibres are covered in this work, along with their uses, applications, and mechanical qualities, as well as how banana fibre might improve mechanical properties.

The article examines the theoretical principles of studying sustainability and security of public budget of the Visegrad Group countries and determines that indicators of the normal functioning of the economy and ensuring a decent social standard of living of the population are reaching the limits of relevant indicators, some of which are approved by international standards. At the same time, the authors identified the absence of a single system of macrofinancial indicators of sustainability and security of public budget proposing to create it, including twelve ratios reflecting levels of debt security, deficit load on the economy, debt load on the population, budgetary independence, efficiency, population well-being, productivity, economic efficiency, as well as the effectiveness of financial support for health and education, elasticity of income and expenditure from the change in GDP of the Visegrad countries. Analytical calculations of the above-mentioned macro indicators in the dynamics made it possible to draw qualitative conclusions on compliance with the sustainability and security of public budget of the Visegrad Group countries, identify possible threats to national economies and prevent the consequences in case of non-compliance with standards. Based on the results of correlation-regression analysis, the authors determined the indicators that have the greatest impact on the resultant factor-the ratio of the level of deficit load on the economy of the investigated countries. It made it possible to analyze the real situation in the economy, to determine the level of sustainability and security of public budget and to give the necessary suggestions and recommendations.

Experimental studies of the non-stationary heat exchange in the system «environment I – body II» have been carried out. It is established that in the body II, which consists of the fluid and thin-walled metal envelope, the characteristic features of the regular thermal mode occur, i.e., cooling (heating) rate of the body II- m = const; heat transfer coefficient between the water (environment I) and body II is practically stable α1 = const; uneven temperatures distribution coefficient in the body II ψ = const. This new notion of the heat transfer regularities in the body II is planned to apply for further development of the experimental-calculation method for the forecasting of the heat exchange intensity in the compound fluid media with limited information regarding thermophysical and rheological properties.

The pale Pilsener-style lager beers produced on a massive and craft scale were taken to analyse their basic physicochemical properties (alcohol content, pH, haze, real degree of fermentation) and volatile compounds profiles. The research was carried out using a beer analyser equipment and a headspace gas chromatography-mass spectrometry method (HS/GC-MS). The findings showed that in terms of physicochemical and flavour attributes, the quality of craft beers differed to a higher degree from the standard Pilsener beer quality than in the case of industrial beers.

In a perspective projected to reduce the atmospheric concentration of greenhouse gases, in which carbon dioxide is the master, the use of microalgae is an effective and decisive response. The review describes the bio circularity of the process of abatement of carbon dioxide through biofixation in algal biomass, highlighting the potential of its reuse in the production of high value-added products.

The study is devoted to the development of proposals for improving the assessment and stimulating the export potential of an innovatively active enterprise. The authors examined the essence and features of the activities of innovatively active enterprises, as well as the impact on their export activities. The conducted theoretical and methodological study allowed the authors to show their vision of the main components of the export potential of the enterprise, and also, in order to assess and analyze the export potential of an innovatively active enterprise, they proposed an economic and mathematical model, a feature of which is taking into account the hidden export potential, which has a significant economic impact. To stimulate the export potential of an innovatively active enterprise, the authors proposed a system of labour force motivation, as well as institutional instruments, which have a significant social impact.

The present environmental condition indicates the immediate need for sustainable materials containing mainly natural elements for composite fabrication. Encouragement of natural fibers in composite materials can significantly reduce the greenhouse effect and the high cost of manufacturing synthetic fiber-based polymer composites. Hence, this study aimed to investigate the physio-mechanical properties of banana fiber (BF) fiber -based epoxy (EP) composites filled with walnut shell powder (WNP). Fabrication was carried out by mixing and cold pressing with fixed BF proportion and varying percentages of WNP (0%, 5%, 10%, 15 wt. %). The results obtained in the study suggest the mechanical properties of the BF/EP composite were enhanced with the addition of WNP as a filler. This is because the WNP filler occupies the spaces in the composite, which bridge the gaps between the banana fibers and the epoxy matrix; also, the inclusion of walnut powder in the BF/EP composites greatly enhanced their wear resistance. The microstructural properties of the composites were examined by scanning electron microscopy (SEM).
