Background Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high organic...

--Gaseous phosphine was found to inhibit biogas formation during the anaerobic fermentation of swine manure. A logarithmic dose-response correlation was obtained with 50% inhibition at a phosphine concentration of approximately 150 ppm. Anaerobic fermentation of acetate and yeast extract measured by biogas formation were not affected at concentrations up to 1000 ppm. Despite the relative tolera...

Die Gewinnung regenerativer Energien boomt, auch Energie aus Biogas wird von staatlicher Seite intensiv gefördert. Das vorgestellte Biogas-Managementsystem unterstützt den Anlagenbetreiber beim effektiven Management der Ressourcen und Kapazitäten – insbesondere unter dem Aspekt, dass moderne Biogasanlagen im Verbund betrieben werden und häufig sehr viele, verschiedene Lieferanten haben. Hier st...

Introduction The co-digestion of manure with other substrates such as energy crops, industrial wastes, or food industry wastes enhances biogas production. The addition of co-substrates to manure can improve the carbon to nitrogen balance which results in a stable and maintainable digestion process [1]. Co-digestion also improves the flow qualities of the co-digested substrates [2]. Perhaps the ...

The aim of this contribution is to present an industrial application of mathematical programming for the simultaneous synthesis of a biogas plant and its heat exchanger network (HEN), within an existing meat company. The heat-integrated model recently developed by Drobež et al. (2010) has been extended with Yee & Grossmann simultaneous optimization MINLP model (1990) for the synthesis of heat e...

Biomass from wetland aquatic grass and buffalo grass can be exploited for biogas production, because this substrate is plenteous and does not compete with food production. In this study, the grass substrate was physically pretreated by boiling with different retention time to increase its biodegradability and was examined in batch mode. Boiling pretreatment suggested that 100 °C with 2 h retent...

Biogas production is becoming increasingly important in the environmental area because, besides treating wastewaters, it also generates energy. Co-digestion has become more and more powerful since it is possible, with the use of abundant and cheap substrates, to dilute the inhibitory effects of various other substrates, making the process of anaerobic digestion more efficient and stable. Biogas...

The chapter concerns with the constructions of the commercial biogas plants as well as the small and household units. Furthermore, the chapter aims at providing a clear description of the structures and constructions of the anaerobic digesters and the used building materials. Ultimately, the chapter answers an important question: how to build a commercial biogas plant and a household unit, and ...
