Digestate is the product of organic materials bioconversion in the process of methane fermentation resulting in the organic matter complex decomposes to simpler organic compounds, mineralized substances, microbial biomass, and biogas, that is consisting mainly of methane (55-70%) and carbon dioxide (30-45%).
The typical technology for biogas production from agrarian materials (manure, litter, corn silage, sugar beet pulp, crop residues, etc.) is methane fermentation in semi-flow type bioreactors.
- what are the features of the digestate;
- about the typical technology of biogas production;
- about the composition of the digestate and its advantages;
- about the important characteristics of the digestate for soils and agricultural production.
