Abstract
The effect of red amaranth and sunflower husk biochar addition on biogas yield in anaerobic fermentation of cow manure was studied. The kinetic description of the process with the help of modified Gompertz model is made. The variants of realization of the considered method of cow manure digestion with amaranth and biochar on the example of Aktobe urban-type settlement (Republic of Tatarstan) are proposed.
