One of the basic aspects of sustainable development strategy involves investments in green technologies, including energy production from renewable sources. Biomass, special organic waste which belongs to “green sources” of energy can be used in the methane fermentation process of biogas production to generate heat and electricity.Biogas power plants have functioned in the Polish energy industry for many years now. On the basis of the data available from Central Statistical Office, in 2014 the ratio of biogas accounted for 7.6% of the structure of primary energy derived from renewable sources in the EU and 2.6% in Poland. An important consideration related to the production of biogas is associated with the applicability of waste resources derived from agricultural production and from the food industry, including pig slurry, slaughterhouse waste, brewing and distilling dregs as well as others. The operation of biogas plants provides considerable benefits to the environment, resulting from the controlled fermentation process and its application in the production of useful energy, as it can provide reduction of the emission of methane and other greenhouse gases. The aspects including the reduction of the volume of waste, environmental protection, fulfillment of the EU obligations and local energy security, form the reasons why communes in Poland should focus their attention on the use of biogas.This paper presents the results of SWOT analysis of biogas production in the context of sustainable development. The assessment of the aspects (strengths, weaknesses, opportunities and threats) and the intensity of their impact were undertaken on the basis of a point scale developed by the authors. The analysis shows that the process demonstrates a number of strengths, which can promote the implementation of positive changes in the environmental and social aspects undertaken on a local scale.

Energy security and independence is one of the key points in sustainable development. In modern conditions of rapid growth and development of technologies, more and more attention is paid to finding practical solutions for environmentally friendly and inexpensive energy production. For a long time, scientists from various fields of scientific activity around the world have been engaged in the development and use of alternative energy sources. The share of renewable energy sources in the generation of electricity around the world is growing steadily, which indicates an increase in the use of energy obtained from alternative sources, such as, for example, wind and sun. These trends testify to the desire of consumers to abandon the use of fossil energy sources and nuclear power plants as much as possible in order to ensure further sister development. Under the current conditions of the COVID-19 pandemic, the demand for electricity worldwide has decreased, however, as the study shows, this pandemic has not affected the development of renewable energy. The article analyzes modern trends in the development of renewable energy, taking into account the experience of the EU countries and leading countries of the world in this area. As a result, it was concluded that in modern conditions, to achieve sustainable development, transformation processes are needed in such an important area as energy. Various processes in the global economy, which contributed to the intensive development of alternative energy sources, served as a powerful impetus for such changes. Many countries have made significant progress in the development of renewable energy.

The task of the national sustainable development strategy is to provide a long term conception for the economy and society, so that this might function and develop in harmony with the environment. Creating the conditions for sustainable agricultural production requires the elaboration and implementation of long-term programs spanning generations. The objective is to find a compromise between the conceptions appearing in the long-term and the short-term programs.In Hungary, several principles, conceptions and proposals have been suggested regarding sustainable agriculture. In the present study, I intend to systematize the above mentioned principles and conceptions, and compare them to the conceptions regarding agriculture in the national strategies of the EU member states. Furthermore, I examine to what extent the agricultural policy of the European Union supports the conceptions regarding agriculture in the strategies. This topic deserves special attention, as the Hungarian national sustainable development strategy is being prepared and is supposed to be finished by the end of 2005.

In December 1999, in Helsinki, the European Council requested the Commission ‘to prepare a proposal for a long-term strategy dovetailing policies for economically, socially and ecologically sustainable development’. The Commission presented this proposal to the Gothenburg European Council in June 2001,1 resulting in the launch of the European Union's strategy for sustainable development.2 In keeping with the resolution that the annual spring European Council take on board responsibility for reviewing progress in developing and implementing the sustainable development strategy, and for offering further policy guidance to promote sustainable development, the Barcelona Presidency conclusions place emphasis upon the internal and external aspects of sustainable development, including the environmental dimension thereof.3 Looking at these documents,4 it is readily apparent that the political profile of sustainable development has been raised over the last year, with the European Council coming to play an important leadership function. Looking more closely at these, and other core documents, it is clear that the theme of environmental governance is very much to the fore, and that a number of strands emerge as crucial to European Union thinking in this respect. This short survey note will highlight a number of these strands, examining them within the framework of more general developments concerning ‘governance’ in the EU, and in particular in the light of the Commission's White Paper on governance issued in the summer of 2001.5 Four broad, and often overlapping, dimensions will be discussed in turn: integration, monitoring/evaluation, participation, and instruments for environmental protection.

Abstract The selected techniques were reviewed and their technological aspects were characterized in the context of multi-phase flow for biogas production. The conditions of anaerobic fermentation for pig slurry in a mono-substrate reactor with skeleton bed were analysed. The required technical and technological criteria for producing raw biogas were indicated. Design and construction of the mono-substrate model, biogas flow reactor, developed for cooperation with livestock buildings of various sizes and power from 2.5 kW to 40 kW. The installation has the form of a sealed fermentation tank filled with a skeletal deposit constituting a peculiar spatial system with regular shapes and a rough surface. Incorporating a plant in such a production cycle that enables the entire slurry stream to be directed from the cowshed or pig house underrun channels to the reactor operating in the flow mode, where anaerobic digestion will take place, allows to obtain a biogas. The paper presents preliminary results of experimental investigations in the field of hydrodynamic substrate mixing system for biogas flow assessment by the adhesive bed in the context of biogas production. The aim of the study was to assessment and shows the influence of the Reynolds number on the biogas resistance factor for the fermentation process in mono-substrate reactor with adhesive deposit. The measurement results indicate a clear effect of the Reynolds number in relation to the descending flow resistance coefficient for the adhesive bed.

The subject matter of this article is incentives for innovations in entrepreneurship. There are two models of entrepreneurship which exist in developed market economies – traditional and innovative. Innovations have never been so important as they are now, which holds particularly true for small and medium-sized businesses. As Peter F.Drucker formulated it, “Innovation is the specific tool of entrepreneurs, the means by which they exploit change as an opportunity for a different business or a different service.” The methods by which innovations are encouraged change from country to country. The choice of such methods depends on economic, political and other conditions for a country&s development. By encouraging innovative activities, governments enhance the effectiveness of innovative systems and create favorable conditions for enterprises to engage in science and technology. For the EU, which falls behind the USA and Japan in so far as innovation technologies are concerned, it is a highpriority task to implement the innovation development strategy and to transform its economy in accordance with the up-to-date model by 2020. The aim of such strategy is to achieve industrial leadership as well as to support business, including small and medium-sized businesses.

In the article the authors have developed an eco-economic mechanism for the formation of a system of national priorities in terms of sustainable development. The mechanism is based on the Concept of Sustainable Development, which improves its theoretical basis: characteristics, principles and components. Their manifestation at the world and national level is taken into account. Diagnosis of the state of the countries is carried out The EU-27 as whole and individual countries, namely Germany, Lithuania, Latvia, Poland, Romania, Estonia, Bulgaria, Slovakia and Ukraine in terms of sustainable development in terms of three key areas - economic, social and environmental. Analytical study of trends in indicators for 10 years for the European Union and Ukraine has led to the conclusion that the application of sustainable development strategy leads to positive results. Based on the concept of sustainable development, a set of defined environmental imperatives and the Strategy for Sustainable Development of Ukraine until 2030, the authors formed a system of national strategic priorities.
