As a result of the conducted research in assessing the possibility of using carbonaceous waste from the woodworking industry of the Leningrad region for heat energy production, harmonious compositions of energy raw materials and methods of their processing were determined. The most rational, as calculations have shown, is the use of large-tonnage woodworking waste for these purposes. At the same time, the most effective ways of processing raw materials and variants of rational location of woodworking enterprises in the Leningrad region depending on the distance to the consumer and prices for alternative energy carriers were proposed.
