Innovative educational program for biogas production carried out at University of Hradec Králové (CZ) and at University of Opole (PL)
2016
W ostatnim czasie rośnie nacisk na budowę biogazowni rolniczych, szczególnie w czesko-polskim regionie przygranicznym. Jest to region, gdzie występują duże obszary gruntów rolnych mogących służyć do zasilania biogazowni. Strategia ta powinna przyczynić się do harmonizacji wspólnej polityki rolnej Unii Europejskiej. W związku z powyższym wzrasta również potrzeba wykształcenia wykwalifikowanych operatorów tych stacji. Pierwsza część pracy obejmuje prezentację akademickiego programu edukacyjnego w dziedzinie fermentacji beztlenowej odpadów i wytwarzania biogazu pochodzącego z produkcji rolnej. Zaprezentowano część innowacyjnego podejścia, które wykorzystywane jest w programie nauczania „Pomiar…
Evaluation of biogas production and usage potential
2016
The aim of the research is the development of theoretical and methodical bases for determining the feasibility of plant raw materials growing for its further bioconversion into energy resources and tec hnological materials to maximize profit from business activities. Monograph, statistics, modelling and abstract logical methods have been used during the research. Directions of biogas usage have been examined. Biogas yields from different crops have been analyzed. It has been determined that high methane yields can be provided from root crops, grain crops, and several green forage plants. So, forage beet and maize can provide more than 5,500 m3 of biogas per hectare. Attention is paid to the…
RESEARCHES ON THE DIGESTERS AND REACTORS WHICH CAN BE USED IN A FARM SCALE BIOGAS PLANT
2014
In the general context of searching integrated system of renewable energy production, this paper present some researches on the reactors and the digesters, as a main part of a biogas plant at a farm scale. After we present the most used types of digesters, we also concentrated over the processes which take place into a digester, one of them being the removal of H2S from biogas (desulphurisation), which can be made by various methods, either biological or chemical, taking place inside or outside the digester. In the case of biological desulphurization outside the digester, we concentrate on the types of reactors which can be used in this case. Beside the well known types of reactors, we pres…
CONSIDERATIONS OVER A BIOGAS PLANT COMPONENTS
2014
This paper starts from the conviction that one of the main environmental problems of today’s society is the continuously increasing production of organic wastes. In many countries, sustainable waste management have become major political priorities in order to reduce pollution and greenhouse gas emissions and to avoid, as much as possible, global climate changes. This problem becomes more and more present in our country too. Production of biogas through anaerobic digestion of animal manure and slurries as well as of a wide range of digestible organic wastes, converts these substrates into renewable energy and offers a natural fertiliser for agriculture. That is why we consider that biogas p…
Complete genome sequence of the hydrogenotrophic Archaeon Methanobacterium sp Mb1 isolated from a production-scale biogas plant
2013
Methanobacterium sp. Mb1, a hydrogenotrophic methanogenic Archaeon, was isolated from a rural biogas plant producing methane-rich biogas from maize silage and cattle manure in Germany. Here we report the complete genome sequence of the novel methanogenic isolate Methanobacterium sp. Mb1 harboring a 2,029,766 bp circular chromosome featuring a GC content of 39.74%. The genome encodes two rRNA operons, 41 tRNA genes and 2021 coding sequences and represents the smallest genome currently known within the genus Methanobacterium. (C) 2013 Elsevier B.V.
