Biogas forms during the organic decomposition process, where biomaterial is
broken down in the absence of oxygen. Biogas mainly consists of carbon
dioxide and methane and is almost identical to the natural gas pumped out
of the ground by the oil companies by its features. Biogas can be produced
from organic wastes of agriculture, industries and households, but also
specially grown energy plants like grass and corn silo. Biogas is used to
produce heat, electricity, vehicle fuel etc.
Biogas is produced in airtight tank where the steady temperature is kept.
The tank is filled with organic waste, which is converted to gas by bacteria.
The correct feeding of the reactor is important for consistent gas production.
During the biogas production process the nourishments are preserved and
become easier to adopt, this makes the digested slurry and dregs more
valuable fertilizer than the raw manure.
Cattle manure is suitable raw material for producing biogas. During the
process, the amount of effective nourishments is increased and the spreading
out features are improved. At the same time, the bacteria that cause animal
and plant diseases and weed seeds are destroyed. The pig manure deodorizes
Gas production can be made more efficient by adding in reactor energy-plants
or organic waste. Fermentation gets more energy out of the plants than other
technologies and at the same time, it allows to save on the fertilization.
