Opis:: Treatment of organic waste is an ecological and economical problem. Searching method for disposal of these wastes, interest is methane fermentation. The use of this process in agricultural biogas plants allows disposal of hazardous waste, obtaining valuable fertilizer, while the production of ecologically clean fuel – biogas. The article presents the characteristics of organic waste from various industries, which make them suitable for use as substrates in agricultural biogas plants.

Opis:: The aim of the research was to determine the exchange rate of carbon dioxide between the atmosphere and the maize field fertilized with the digestate from an agricultural biogas plant. The studies considered both the amount of net carbon dioxide emission which is the difference between the amount of this gas absorbed by vegetation and its amount emitted from the whole ecosystem of the field as well as the emission resulting only from the changes occurring in the soil. The CO₂ emission from the entire field was measured by the eddy covariance method with a set of LI-7500A analyzer (LI-COR Biosciences, USA) for measuring the CO₂/H₂O concentration in air and 3-axis WindMaster ultrasonic anemometer (GILL, UK). The data from the analyzers were recorded at 10 Hz, while the CO₂ streams were calculated using the EddyPro 5 software. The soil emission was determined with the chamber method using the automated ACE measurement system (ADC BioScientific, UK). Until the maize reached maturity, the study was carried out once a week, at 10.00 – 14.00. During each measurement day, the basic meteorological parameters were measured as well. The obtained results showed a clear relationship between the plants development phase and the size of the net CO₂ exchange. The negative values of carbon dioxide streams, indicating the absorption of this gas from the atmosphere, were observed already in the case of plants with a height of approx. 25 cm, while the maximum values were reached after the release of panicles by maize. The carbon dioxide emission from soils, measured at the same time, was maintained throughout the entire research period at a similar low level, undergoing only slight fluctuations associated with variable soil moisture. The study showed that the maize field, almost throughout all growing season, can be treated as a sink of atmospheric carbon dioxide, reducing its emission from agriculture.

Tytuł:: Agricultural Biogas Plants as a Chance for the Development of the Agri-Food Sector
Autorzy:: Czekała, W.

agricultural biogas plants
Opis:: Agricultural biogas plants are an important source of energy, where the substrates from agricultural crops can be used. However, these plants need a daily input of biomass in the quantities up to several dozen tons. A few years ago, the most important substrate used for biogas production was maize silage. However, currently, there is a trend to limit the use of the afore-mentioned substrate. This is mainly due to the high cost of the substrate and the conflict over the rational use of valuable soils for biomass production for energy purposes. In the paper, the author undertook the attempts to discuss the possibility of limiting the use of raw vegetable materials for energy production, replacing them with agri-food production waste.

Tytuł:: Biogas Production from Raw Digestate and its Fraction

Opis:: The digestate from an agricultural biogas plant is most commonly used as a fertilizer. However, many studies are being performed to develop other ways of managing this substrate. The aim of this study was to determine the biogas and methane efficiency for digestate as well as the solid and liquid fractions from separation of digestate. The material for the research came from a real scale agricultural biogas plant. The separation of the digestate into two fractions was carried out using a mechanical press. The studies on the methane fermentation process were carried out under mesophilic conditions (37–39°C) in the Institute of Biosystems Engineering at the Poznań University of Life Sciences. It was found that the biogas and methane efficiency for the raw digestate and liquid fraction obtained from its separation is very low. For raw digestate it was 2.9 m³ of biogas from 1 Mg fresh matter (FM), including 1.58 m³ methane. For liquid fraction after separation, the biogas efficiency amounted to 1.52 m³ from 1 Mg, including 0.78 m³ of methane. In turn, for the solid fraction, the biogas efficiency was 102.93 m³∙Mg^-1, including 54.99 m³∙Mg^-1 of methane. The research results indicate that the possibility of using the digestate solid fraction for energy production (e.g. secondary methane fermentation) or the production of solid biofuels.

Opis:: The aim of the study was to demonstrate produced biogas dependence on batch composition as agricultural waste. Research was conducted in biogas power plant Biogas Adler, which was the first agricultural biogas plant built in Podlaskie province. The analysis showed in analyzed biogas production of biogas from waste from agricultural activity, is a good way of their utilization, while producing heat and electricity. Among the three analyzed substrates the highest efficiency of biogas production is characterized by corn silage and manure. Potato pulp significantly reduces the efficiency of biogas production. Independently of the composition and quality of substrates, to produce 1 MWh of the biogas plant consumes approx. 457 m³ of biogas.
