Sources of biogas are numerous.

Biogas can be found in many areas of daily and industrial life such as: Agriculture with breeding excrements (liquid manures), within the context of environmental protection applications, the biogas results from urban waste water treatment or industrial food-processing or those arising from the paper pulp production, from the fermentation of household disposal, from landfill grounds or from waste treatment in digesters.
HIBON Process blowers are used for the agitation of digesters or for the transfer of the biogas for supplying distillers, boilers, heat engines and generating sets, of system of cogeneration...
In food industries the same application is used for CO2 recovery in sugarmill, and in agriculture on the liquid manures of breeding.
