“…Thanks to biological treatment, the waste generated in biogas plants can be used in a variety of ways. According to studies [19,20,51,52], the most common use of fermentation waste is as a fertiliser in agriculture, which was also mentioned in this study. That corresponds with approaches observed by Grešlová et al [53] in different countries, where materials from agricultural production can support other processes, re-shaping the energy metabolism of these areas.…”

“…Biogas plants also generate waste, and the amount of waste varies. Scientific studies say that the fermentation waste is about 85-95% of the weight of the raw materials used [20,[48][49][50]. Thanks to biological treatment, the waste generated in biogas plants can be used in a variety of ways.…”

The circular economy is an economic concept opposite to the current linear system. One of its main principles is to seek to minimise waste by reusing seemingly useless raw materials. Biogas plants are places where energy can be recovered from waste. In order to boost the environmental benefits of this concept, it is important to rely on local systems (including supply chains). Therefore, the aim of this study was to examine whether biogas plants in Poland operate in a circular manner from the perspective of locality. The analysis was based on questionnaire surveys concerning the nature of the facilities’ operations, divided into biogas plants located at sewage treatment plants, biogas plants based on municipal waste and agricultural biogas plants. On the basis of the data obtained, statistical and spatial analyses were carried out to verify the installed capacity of the facilities, the distance from which they obtain their substrate and the use of the biogas produced. The results of the study confirm that the functioning of biogas plants located in Poland is, in most cases, of a local character, fitting into the objectives of a circular economy. Biogas plants that are characterised by the lowest transportation needs are biogas plants located next to sewage treatment plants.

The impact of biochar dosing with simultaneous fertilization with a biogas plant digestate on the volumetric density of soil

et al. 2019

View full text Add to dashboard Cite

The paper analyses the impact of biochar on the volumetric density of the soil, with simultaneous fertilization with an agricultural biogas plant digestate. For the purpose of the research, 10 experimental fields were prepared for the study, in accordance with good agricultural practice. To verify the results, a single-factor variance analysis was performed, which demonstrated a significant differentiation between the dosing of the biochar and the values of the volumetric density of the soil. Using the digestate simultaneously with the biochar addition further increased the disparity in the soil's volumetric density between the respective biochar doses.

The increased demand for energy determines the need to search for its next sources. One of them could be renewable energy sources, whose importance is increasing, among others, due to the limited resources of fossil fuels. In addition, renewable energy production has many benefits, mainly environmental and economic. Moreover, the social aspects associated with it cannot be ignored. The aim of this work was to discuss selected social benefits resulting from the production of renewable energy. Among the most important advantages of renewable energy sources is their local aspect, since energy production solves many regional problems, mainly related to its transport. The issue of energy security is also essential. In the case of biofuel production, the possibility of involving waste in energy production is extremely beneficial. The use of renewable energy itself directly affects the improvement of the environment, which in turn has a positive effect on people. Nowadays, sustainable development is one of the most critical challenges of humanity. These activities are closely related to the use of renewable energy sources. It is important to pay attention not only to subjects related to the environmental and economic aspects but also the impact of renewable energy sources on society.
