Profitability of biogas plants The profitability of biogas plants is determined by a number of factors: The substrate costs a considerable cost factor, with a share of more than 50% of the variable expenses. Another crucial factor for the profitability of the plant is the utilisation rate of the plant. Most BIOGAS plants work after a continuous ...
The odors of a biogas plant are at the forefront of the concerns expressed by citizens when such a project is implemented in the territory. Project developers must, therefore, take into account this key issue to promote the success of the biogas plant and keep harmonious cohabitation with the local communities.
In continuous test the mixture of CCWJ and SM (25:75, % vol. basis) produced biogas yield of 352 mL/g VS added which is around 11% higher compared to biogas yield from SM alone.
Biogas is formed as a result of anaerobic fermentation of biomass in the presence of water.. Benefits of biogas technology: Some of the benefits of the biogas technology are given below;. Biogas provides clean gaseous fuel for cooking and lighting. Chemical fertilizers can be done away with since the digested slurry formed from the biogas plants can be used as enriched bio-manure.
and lighting. Thousands of agricultural biogas plants are in operation in Europe and North America, many of them using the newest technologies within this area, and their number is continuously increasing. In Germany alone, more than 3.700 agricultural biogas plants were in operation in 2007.
The biogas plant consists of two components: a digester (or fermentation tank) and a gas holder. The digester is a cube-shaped or cylindrical waterproof container with an inlet into which the fermentable mixture is introduced in the form of a liquid slurry. The gas holder is normally an airproof steel container that, by floating like a ball on ...
