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.

Tytuł:: Agricultural Biogas Plants as a Chance for the Development of the Agri-Food Sector

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.
