Figme 13 shows a biogas plant commoidy used in countries like Demnark, Germat r, and Austria. The animal manure from the stable is mixed, stored for a short time, heated, and pumped into the biogas reactor. This mixing facility is driven by a slow-moving electric motor. 

Compostable plastics provide little relief as to the increasingly rare landfill space available, since their substance is hardly reduced in the process Anaerobic degradation processes in fermenters degrade about 35-60 % by weight of the mass placed in the system for fermentation. If the landfill corpus is considered to be a (nonoptimized) biogas reactor, degradation rates of the biodegradable materials (BM) on the order of 30 % would appear to be realistic.

A thermophilic biogas plant in Boden, Sweden, with two preheating tanks (70 °C) and a 1300 biogas reactor using thermophilic digestion (55 °C) [49]. 

Just as there are various ways to enhance the heat transfer of other traditional heat exchangers, there are various ways to improve the heat transfer of heat exchangers used in an outside heating loop of a biogas reactor (1) increasing the... 

Given that gas mixing is quite complex because of the involvement of turbulence and non-Newtonian rheology, as well as phase-interaction [70], CFD modeling helps research the flow configuration in airlifting biogas reactors. Vesvikar et al. [71]... 

Fluidized bed biogas reactors combine immobilization and hydraulic mixing (see Figure 23) to achieve a high reactor biomass hold-up and a long mean cell residence time [74]. The density of carrier or supported materials needs to be smaller than the...
