Ukraine has enough biomass resources for biogas production. However, this energy potential is not used sufficiently. This research is aimed at examining the current experience of commercial biogas systems in the Europe Union and its adaptation for Ukraine. Special attention was paid to economic indicators, such as specific investment costs, production costs (biogas, biomethane, and electricity), and incentives. Using statistical data for the European Union and Ukraine, the biogas potential for Ukraine (based on European experience) was determined. The economic competitiveness of biogas production was evaluated compared to alternatives, such as photovoltaic, wind power, biomass, conventional fuels, and liquid biofuels. The results showed that biogas complexes have higher specific investment costs and produce more expensive electricity. It was highlighted that agricultural residues and industrial waste are sustainable feedstocks for biogas systems. A perspective biogas plant is a plant that is an integrated part of the circular bioeconomy that is based on organic residues. Biomethane production (as a substitution for vehicle fuel) combined with capture and utilization of carbon dioxide is a more profitable pathway. Awareness and perception of the importance of biogas are key factors for the development of the biogas industry. To develop an effective strategy for the biogas industry, it is necessary to create a positive image in order to raise awareness and knowledge of biogas technologies.

Implementation of the circular economy is one of the priorities of the European Union, and energy efficiency is one of its pillars. This article discusses an effective use of agri-food industry waste for the purposes of waste-to-energy in biogas plants. Its basic objective is the comparative assessment of the eco-efficiency of biogas production depending on the type of feedstock used, its transport and possibility to use generated heat. The environmental impact of the analysed installations was assessed with the application of the Life Cycle Assessment (LCA) methodology. Cost calculation was performed using the Levelized Cost of Electricity (LCOE) method. The LCA analysis indicated that a biogas plant with a lower level of waste heat use where substrates were delivered by wheeled transport has a negative impact on the environment. The structure of distributed energy production cost indicates a substantial share of feedstock supply costs in the total value of the LCOE ratio. Thus, the factor affecting the achievement of high eco-efficiency is the location of a biogas plant in the vicinity of an agri-food processing plant, from which the basic feedstock for biogas production is supplied with the transmission pipeline, whereas heat is transferred for the needs of production processes in a processing plant or farm.

AbstractRecently, there is a growing pressure on a rapid construction of agricultural biogas plants, particularly in the Czech-Polish border region. It is an area with large expanses of agricultural land which can serve to supply biogas plants with biomass. This strategy should contribute to harmonize the common agricultural policy of the European Union. A need for qualified operators of these stations on this territory is also increasing. Therefore we first include a demonstration of an education program for students in the field of agricultural waste anaerobic fermentation and biogas production. We present here the first part of an innovative approach which we use in the teaching program “Physico-technical Measurements and Computer Technology” at the Faculty of Science at the University of Hradec Kralove and also in the education of internshipers from the Faculty of Natural Sciences and Technology at the University of Opole. There are requirements to fulfil labour market expectations and to make this subject more attractive for the students. Students’ theoretical and practical preparation constitutes a comprehensive source of knowledge and skills required in a real life job. Joined theoretical and practical knowledge gained by students, reinforced by the skills developed during task analysis followed by their solution, provides the future graduate higher quality abilities and better position in the labour market.

Aim of study: The utilization of agricultural residues may become one of the major sources for production of energy from biomass. The objective of this paper was to analyse the type and quantity of agricultural residues and to determine their energy potential.Area of study: The Međimurje County (north Croatia).Material and methods: The paper analyses three models of sustainable agricultural residues management applying the multi-criteria analysis. The assessment included potentially available quantities of residues in crops, fruit, viniculture and livestock production. For determining the most appropriate model of residues utilisation the multi-criteria analysis was applied.Main results: The results show that total quantities of agricultural biomass amount to 323,912 t with energy potential of 1,092 TJ annually. The largest sustainably available potential of agricultural biomass consists of biomass from arable crops production, with total quantity of 33,670 t followed by 281,233 t of manure from livestock production. The lowest share of potential biomass are pruning residues in fruit and grapevine production with total available residual quantity of 8,109 t. Also, it results from the multi-criteria analysis that a central large scale plant for biogas production is the most feasible facility for such production.Research highlights: The results of this paper provide ground for further development of the models for assessing the sustainability of using agricultural residues, and they can also serve as a basis for assessments of bioenergy projects in specific regions of the European Union.

The study examines the effect of temperature fluctuations on biogas production efficiency in biogas plants with the aim of evaluating the temperature flexibility of the process. Laboratory scale batch reactors were prepared with the chosen substrate (Dried Distillers Grains with Soluble, DDDS) and the study was conducted in three batches. A biogas formation potential test was implemented in each batch in a temperature-controlled room and in a temperature controlled water bath. The temperature changes took place on the third day of tests to evaluate the effect of 5°C, 10°C and 15°C increases on biogas production efficiency in separate test sets. Batch experiments showed that it is possible to ensure process recovery after 5°C and 10°C increases. Overall, the specific biomethane production was obtained between 364-412 Nml CH4 / g oDM. Unlike 5°C and 10°C increases, after 15°C increase a lower methane content was obtained. These results show that it is possible to have flexible temperature operation in the process, even with high-temperature increases.

The necessity to investigate suitable alternatives to conventional fossil fuels has developed the interests in many renewable energy alternatives, especially biomass resources which are widely available and allow to reach both environmental and socio-economic improvements. Among the bioenergy solutions the anaerobic digestion technology makes it possible to produce biogas by reusing and valorising agricultural residues and by-products. In Southern Italy, to date, the development of biogas sector is still very limited, despite the importance of the agricultural sector, especially of citrus and olive cultivation. For this reason, in previous studies the availability of two by-products, i.e., citrus pulp and olive pomace, was analysed in order to choose the most suitable area for a sustainable development of new biogas plants according to the new Biogasdoneright concept. In this paper, after a resume of the multi-step methodology which allowed the computation of biogas production, it was demonstrated that 15.9 GWh-e electricity and 24.5 GWh-e heat per year could be generate by reusing only these two kind of by-products, and could satisfy approximate 17% of the total electricity demand of the agricultural sector (90.2 GWh-e/year) in Catania.

In the European Union (EU), the use of fossil fuels brings several disadvantages, as they are the main culprits responsible for pollutants and GHG emissions. The increasing demand for sustainable fuels leads to the research of alternative technologies, such as biogas production from lignocellulosic materials. Therefore, the acquisition of biomass from marginal areas under Danish conditions has been evaluated in terms of alternative harvesting equipment: an automated robot (Grassbot) versus a regular tractor for key grass materials used for biogas plants (chopped, unchopped, and baled grass) and compared regarding operational, economical, and environmental performances. The evaluation uses two operations models (IRIS and DRIFT) to consider the field characteristics, machinery characteristics, etc. Selected results show that in terms of fuel consumption, chopping, and mowing are the most demanding operations, and that there is no significant difference between the harvesting equipment regarding CO2 emissions.

Analyses of statistical data were made and their results discussed in this article to identify the level of Poland’s energy security and to determine the role of agriculture in ensuring it. It has been demonstrated that coal continues to be the staple resource for the generation of energy in Poland. The current demands and requirements concerning the reduced consumption of non-renewable resources and Poland’s obligations towards the European Union regarding the production of energy from renewable resources—all these considerations contribute to the promotion of a skillful development of energy crop farming, which, in Poland, is likely to be very successful. Agriculture plays an important role in ensuring Poland’s energy security, and this branch of farming can grow dynamically provided adequate legal regulations and promotion are in place. The chief resource for renewable energy generation is biomass. Straw and biogas production in agricultural biogas plants are two solutions whose full energy production potential still awaits to be tapped.

Biomass Resources

An area of the Odessa oblast includes 26 administrative districts with developed agricultural traditions. The productivity of main grain crops in the Odessa oblast comprises several million tons every year. Annually, the vegetable residues in the Odessa oblast upon harvesting make a significant amount. Biomass includes both nutritional and energy potential, which requires new approach in the storage and treatment. At the same time, the current problems with high cost of the traditional energy sources create various obstacles in the fields of agricultural activity. Recently, considerable attention is focused on the process of  biological conversion of the biomass to methane. Rising segment of biomass application in the energy strategies all over the world implies the need for greater accumulation of biomass resources to meet the demand. The purpose of this publication is an assessment of vegetable biomass amount in the districts of the Odessa oblast, potential of nutrients and biogas energy generated from the biomass. The analysis corresponds to the search of new alternative energy resources and the rational use of organic biomass. The agricultural biomass residues are the resource category with relatively high regeneration capacity. This property can be used for producing nutrient-rich organic fertilizers and high-energy biogas to compensate the traditional fossil fuel dependence. The availability of agricultural biomass resources was found to demonstrate the great perspectives for the bioenergy sector, first of all in view of the adopted waste management strategies.

Globally, the pollution prevention goals transposed in the Kyoto Protocol, require sustainable solutions regarding the management of organic waste from both agricultural, and livestock farms. Biogas production by anaerobic digestion of organic wastes and residues provides a range of socio-economic benefits, but also environmental, thus contributing to monitoring the complex relationship between human health and the environment. The European Union policies regarding renewable energy systems (Europe 2020 Strategy – A strategy for smart, sustainable and inclusive growth and Green Paper „Towards a European strategy for the security of energy supply“), highlights that the production of renewable energy, reducing greenhouse gas emissions and a sustainable waste management, are essential for sustainable development in the future. In this context, this paper will review aspects of biogas production by anaerobic digestion of organic waste, stages of anaerobic digestion process and concepts of biogas plants used in European countries.

Subject. The article considers the concept of circular economy, which has originated relatively recently in the academic literature, and is now increasingly recognized in many countries at the national level. In the European Union, the transition to circular economy is viewed as an opportunity to improve competitiveness of the European Union, protect businesses from resource shortages and fluctuating prices for raw materials and supplies, and a way to increase employment and innovation. Objectives. The aim of the study is to analyze the incentives developed by the European Commission for moving to circular economy, and to assess their effectiveness on the basis of statistical analysis. Methods. I employ general scientific methods of research. Results. The analysis of the EU Action Plan for the Circular Economy enabled to conclude that the results of the recent research in circular economy barriers, eco-innovation, technology and infrastructure were successfully integrated into the framework of this document. Understanding the root causes holding back the circular economy development and the balanced combination of economic and administrative incentives strengthened the Action Plan, and it contributed to the circular economy development in the EU. Conclusions. The measures to stimulate the development of the circular economy proposed in the European Action Plan can be viewed as a prototype for designing similar strategies in other countries, including Russia. Meanwhile, a more detailed analysis of barriers to the circular economy at the level of individual countries and regions is needed.
