Abstract—The production of synthesis gas by the two-stage thermal conversion of agricultural waste of plant origin (straw and sugarcane bagasse) was studied. It was established that this method allows one to obtain 1.21–1.24 m³ of synthesis gas from 1 kg of feedstock. The heat of combustion of the resulting gas was 10.6–11.0 MJ/m³, and the yield of biochar was 26.46–29.90% on a feedstock weight basis.
