Quality of fermented residue to be used as a fertilizer after biogas production
The scope of this research was to analiyse the fermented residue after biogas production from different raw materials. The research was carried out on three facilities for biogas production using mesophilic anaerobic fermentation. The raw materials used for biogas production were pig manure, caw and chicken manure. Chemical composition was determined and bacteriological tests of the samples taken. It was found that the fermented residue in all of the samples, all of which are mildly alkaline, contains a low level of dry matter, 70% of which is organic matter. Biogenic elements were present in moderate concentration ; the values of heavy metals were within approved limits. This analysis leads to the conclusion that the fermented residues of all input materials can be used in agricultural production, especially so in plant production and grassland cultivation. Mesophilic and thermophilic microorganisms were found in the fermented residue samples, but there were no criophilic microorganisms and no pathogenic bacteria.
