ABSTRACT:
A method of rejuvenating and preserving a forest by transforming wood waste. Tree species are identified in a forest area. Equipment is then selected or modified based on the identified tree species. Wood waste of the identified tree species is gathered and transformed into useful wood derived end products with the selected or modified equipment. The wood waste may be transformed into wood charcoal and used as a fuel in a furnace to heat a boiler to produce steam. The steam is used to drive a turbine that runs an electric generator to produce electricity to run equipment that transforms the wood waste.
