Gayle, D. (2012, May 30). But how long a compost pile stays at any given temperature depends on a variety of factors, primarily the moisture content, frequency of turning the pile, size of the compost pile, exposure to oxygen, and carbon to nitrogen ratio. The thermal degradation and ignition point of wood and plywood may be generalized by the following: 230 to 302 F (110 C to 150 C): The wood will char over time with the formation of charcoal.
