“…Earlier studies present barriers to the functioning of agricultural biogas plants without any particular use of the typology (Pawlak, 2013;Mateescu et al, 2008). Other studies indicate the following barriers: political, economic, social, and technological (Situmeang et al, 2022;Igliński et al, 2020) supplemented with market barriers (Monjurul et al, 2022;Nevzorova & Kutcherov, 2019).…”

The article aims to identify barriers related to developing agricultural biogas plants in Poland. The secondary data was supplemented by primary data from a questionnaire conducted among employees of an enterprise whose biogas production is one of the elements of the circular economy. The results of the research revealed that the majority of respondents indicated external, systemic and developmental obstacles. The largest percentage of responses concerned the lack of stable legal regulations in the scope of renewable energy sources, including biogas plants, and the lack of programs financing the construction of agricultural biogas plants. Moreover, the respondents pointed to the proposals that could improve the development of agricultural biogas plants in the future. The respondents considered updating and ensuring the profitability of investments in the situation of significantly higher expenditures, growing costs of business and debt servicing through the reference price as a significant motivator, as well as inclusion in the support system of tariffs guaranteeing a stable income for at least 15 years. Barriers to developing agricultural biogas plants in Poland remain unchanged, and the awareness of the positive impact of agricultural biogas plants on many levels is still very low.

“…For example, in Romania, the production and use of biogas is uncommon due to the market barriers, lack of knowledge and experience (farmers, installation operators, etc.) and insufficient access to sources of finance (Mateescu et al, 2008). In Rwanda, however, the main obstacles to biogas installations include financial, technical, socio-cultural and institutional barriers.…”

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.

“…Anaerobic digestion of fruit juices can provide a clean and an environment-friendly gas. Biogas is composed mainly of methane and carbon dioxide, as well as a variety of other compounds such as: ammonia, hydrogen, hydrogen sulfide, etc., which will then be converted into electricity and heat in the combined heat/power generators (Mateescu et al 2008). The conversion pathway of the substrate can take place according to four stages: hydrolysis, acidogenesis, acetogenesis, methanogenesis.…”

The aim of this study is to investigate the use of ultrasound pretreatment as potential technique to solubilize organic matter and fermentation of fruit juice effluents in anaerobic batch reactor. The efficacy of ultrasound pretreatment has been assessed at low frequency of 20 kHz and at different sonication times (20, 40 and 60 min). Compared with control, the amount of biogas produced increased by 47, 57 and 60% for sonication times of 20, 40 and 60 min, respectively. Methane content of the produced biogas was about 59% in the control and 64% in the case of effluent subjected to ultrasonic for 60 min. After 20 days of anaerobic digestion of the fruit juice effluents, the efficiency of COD increased by 9, 31 and 35% with respect to control for sonication times of 20, 40 and 60 min, respectively, corresponding to total sugars uptake efficiency of about 35, 51 and 54%, respectively. The modified Gompertz equation was used to describe the cumulative biogas production. A good agreement was found between simulated and experimental data.
