“…Stabilized residue (digestate) can be used as fertilizer after the fermentation process (Marada et al [30]). Since agricultural AD plants process specific agricultural products, be they of plant or animal origin, whose production is spatially rooted in different natural conditions, it can be stressed that the location of agricultural AD plants is highly dependent on this production, especially since these products have a low value/weight ratio, making them rather expensive to transport (mathematical models of this dependence were recently reviewed in Balaman and Selim [31]; Kythreotou et al [32]; Neiva de Figueiredo and Mayerle [33]). …”

There is fundamental agreement about the environmental benefits of renewable energy technologies, but unintended consequences arising from their deployment are frequent sources of conflicts. The Czech Republic has committed itself to supply 13.5% of its electricity consumption from renewable sources by 2020. High state incentives for renewable energies have been provided to achieve this target, however critical questions can be asked about the appropriateness of the design of the supporting frameworks which caused a boom in photo-voltaic (PV) installations on agricultural land, as well as a boom in the installation of agricultural anaerobic digestion (AD) plants fueled by dedicated energy crops. This paper analyses the diffusion of agricultural AD plants in the Czech Republic, focusing especially on locational characteristics in relation to the quality of agricultural land, agricultural and population census data. Statistical analysis of those spatial datasets show that agricultural AD plants are mostly located in less favourable agricultural areas, in regions having recently experienced a reduction in cattle breeding, and in regions with significant increases of sowing areas of green maize. These findings suggests shortcomings in the supporting policy for AD plants in the Czech Republic, resulting in unintended environmental consequences, and missed opportunities to enhance energy self-sufficiency and resilience in the countryside.

“…A computational fluid dynamics (CFD) model that characterizes gas mixing in anaerobic digesters was developed by Wu (2014 Tracer studies continue to be a reliable means of assessing digester mixing performance in large scale digesters. Often in large scale digesters, it is difficult to encounter ideal mixing, and the actual complex flow behaviors is very different to constant volume complete mixed systems assumed by ADM1 (Kythreotou, 2014).…”

The gas generated by anaerobic fermentation of organic wastes is called biogas. Since it contains methane, it can be burnt and so it can be used as an alternative energy source. The production of biogas is an anaerobic treatment process, it is important to understand the basic biochemistry and microbiology of anaerobic systems. This study demonstrates the kinetic study to find out the best microbial kinetics which will be necessary for the design of an anaerobic fermenter. For this purpose, chicken manure and chicken manure with inoculation culture were used. Experiments were operated under mesophilic conditions in laboratory type glass fermenters each having a volume of ten liters.
