Hermetia illucens
Opis:
In modern agricultural biogas plants, the biowastes are being increasingly used for the biogas production. The food waste is also widely used in larvae breeding. This is an important because, based on biowaste, its proper management and green energy production is possible. This study aims to determine the biogas and methane efficiency of the Hermetia illucens larvae that were fed using the food waste. In the research on the biogas and methane efficiency, the Hermetia illucens larvae were used. The total solids (TS) of the substrate equals 30.35%, and the volatile solids (VS) content was 92.31% of TS. The larvae were fed only with the food waste of plant origin. The obtained substrates were homogeneous. The experiment was carried out under mesophilic anaerobic digestion conditions – 39°C in the 21-chamber biofermentor set in the Institute of Biosystems Engineering in Poznań University of Life Sciences. The anaerobic digestion process in the batch reactor ran correctly. Fermentation inhibition was not detected. The biogas efficiency for larvae amounted to 198.75 m3∙Mg-1 fresh mass (FM). On the other hand,the methane efficiency, amounted to 127.73 m3∙Mg-1, at the methane concentration of 64.27%. On the basis of the research, it was found that the larvae feeding on food waste can be used directly as anaerobic digestion in the bioconversion process.

Opis:
Przedstawiono potencjał biogazu rolniczego bazującego na wykorzystaniu bioodpadów i roślin specjalnie przeznaczonych dla biogazowni. Określono zalety energetyki biogazowej jako w pełni kontrolowalnej oraz zestawiono je z problemami stwarzanymi przez energetykę niestabilną w kraju i zagranicą. Przedstawiono także kierunki rozwoju sektora biogazu rolniczego w Polsce.
The paper presents the potential of agricultural biogas based both on the use of bio-waste and plants dedicated to biogas plants. The advantages of biogas power engineering were determined as fully controllable and compared with problems generated by unstable energy. The directions of development of the agricultural biogas sector in Poland were also presented.

Opis:
Energy production from renewable sources is one of the main ways to fight against global warming. Anaerobic digestion process can be used to produce biogas containing methane. In the light of the growing demand for substrates, a variety of raw materials are required. These substrates should be suitable for anaerobic digestion, and processing them need to provide the desired amount of energy. This paper aims to discuss the agricultural biogas market in Poland, its current state, and the possibility of development during energy transformation, in particular in terms of using waste as a substrate for energy production. In February 2022, there were 130 agricultural biogas plants registered in Poland. On the other hand, in 2020, 4,409,054.898 Mg of raw materials were used to produce agricultural biogas in Poland. Among all the substrates used, waste played a special role. With the right amount of raw materials and proper management of a biogas plant, it is possible to produce electricity and provide stable and predictable heat supply. Bearing in mind the development of the Polish and European biogas markets, attention should be paid to ensure access to raw materials from which chemical energy in the form of biogas can be generated. Due to limited access to farmland and the increasing demand for food production, one should expect that waste will be increasingly often used for biogas production, especially that with high energy potential, such as waste related to animal production and the meat industry.

Opis:
Digestate from a biogas plant can be a valuable organic and mineral fertilizer. Quantitative proportions of cosubstrates used in three agricultural biogas plants in Poland were analyzed. The composition of digestates was examined and large differences in the content of macronutrients were found, especially N and K. On the basis of the factors used to calculate emissions from the production and use of artificial fertilizers, the greenhouse gas (GHG) reduction resulting from replacing mineral fertilizers with digestate was calculated. In terms of 1 Mg of fresh digestate, this reduction may not seem large, as it amounts to 27.9–61.6 kg of CO2 eq, but it should be taken into account that digestate contains little dry matter. The annual amount of digestate used on an area of 1 ha allows avoiding GHG emissions of 25.8–44.5 Mg CO2 eq.
