The aim of the study was to evaluate of Festuca arundinacea Schreb. spec. Rahela (Tall fescue) and Spartina pectinata L. suitability for biogas production. Biomass of investigated C3 and C4 grasses was grown in Experimental Station of Warsaw University of Life Sciences in Skierniewice, harvested on the 30th of June 2014 and ensilaged. Methane fermentation of experimental silages was carried out under...
Decreasing amount of fossil fuels in the world encourages the searching of alternative energy sources. In this time of energetic crisis, the production of hydrogen is an interesting solution. Hydrogen does not produce any contaminating emission. The aim of this study was to build a project installation that produces gas biofuels and define the potential biohydrogen and biogas possible to produce from...
Anaerobic digestion is a complex, multi-step biological process. Control of this process can be carried out by analyzing the parameters of dry matter, organic matter and the dry matter concentration of volatile fatty acids (VFA). The aim of the study is to assess the possibility of using near-infrared spectroscopy in the construction of calibration models of dry matter content in the fermenting mixture...
The paper presents the issue of the influence of the conditions of maize silage storage on its energy value in the process of methane fermentation. For this purpose, the biogas and methane efficiencies of silage stored under anaerobic and aerobic conditions have been compared. On the basis of executed studies, it has been stated that the process of silage storage and its protection against the contact...
Ensuring the profitability of working biogas plants is a key factor for the development of biogas market. Apart from the price obtained for sold electricity, the substrates are the most important factor, particularly the ratio of their acquisition cost to methane efficiency. Thus, the objective of this paper was energy and economic analysis of the typical biogas plant with a capacity of 1 MWe working...
The most troublesome waste from the poultry industry is the manure produced in Poland in the amount of 2.5 million tons per year. It is a substrate with high energy potential whose potential is, however, used very little. Research conducted at the Institute of Biosystems Engineering at the University of Life Sciences in Poznan showed that the biogas efficiency of substrate is 121.40 m3⋅Mg - 1 fresh...
The aim of this work was to undertake a study to determine the amount of biogas emitted from fractions prepared from sugar beet leaves. Four types of combinations of batch mass were subjected to analysis. Tests were conducted over a period of 30 days. Measurements were taken twice a day, at the same time, from the moment of placing the batch into fermenters until the end of fermentation. In this study,...
