The values of the highest heat of combustion for the dry ashless state of combustion of 35 samples of vegetable raw materials and 35 charcoal were determined. The need for calculating indicators of their technical and elemental analysis was established. Mathematical and graphical relationships between the actual and estimated values of the highest heat of combustion of plant raw materials for the production of biogas and charcoal were developed. A statistical analysis of the dependence data was performed. The results of the analysis indicate the adequacy of the developed dependencies, and allow us to draw a conclusion about the possibility of predicting with high accuracy the value of the higher heat of combustion of vegetable raw materials by carbon or oxygen content, and charcoal  for this determination of the yield of volatile substances or non-volatile carbon.
