Field-Proven Strategies for Reducing Volatile Organic Carbons from Hardwood Drying
Drying hardwood oriented strand board (OSB) flakes leads to a very sharp rise in VOC concentration late in the process. Methanol and aldehydes, the principal VOCs released, arise from wood degradation, which accelerates when the wood is almost dry (
