Biogas

A product of fermentation of organic waste, which can be used as fecal residues, sewage, household waste, slaughterhouse waste, manure, litter, and silage and algae. It is a mixture of methane and carbon dioxide. Another product of processing household waste in the production of biogas are organic fertilizers. The technology of production is associated with the transformation of complex organic substances under the influence of bacteria that carry out methane fermentation.

At the beginning of the process homogenization of the waste mass is carried out, then the prepared raw material is fed with a feeder into the heated and insulated reactor, where the methane fermentation process takes place at a temperature of approximately 35-38 ° C. The mass of waste is constantly mixed. The resulting biogas is fed to a gas generator (used to store gas), and then fed to an electric generator.

The resulting biogas replaces conventional natural gas. Can be used as biofuel, or generate electricity from it.

Biohydrogen

It can be obtained from biomass by a thermochemical, biochemical or biotechnological route. The first production method is associated with heating the wood waste to a temperature of 500-800 ° C, which results in the evolution of a mixture of gases – hydrogen, carbon monoxide and methane. The biochemical method uses the enzymes of the bacteria Rodobacter speriodes, Enterobacter cloacae, which cause the production of hydrogen in the splitting of plant residues containing cellulose and starch. The process proceeds at normal pressure and low temperature. Biohydrogen is used in the production of hydrogen fuel cells in transport and energy. Wide application yet does not have.
