Zusammenfassung:	The disclosure relates to a method for reducing volatile organic compounds (VOC) from wood chips for wood fibre production in a processing system, at least comprising the following consecutive steps: a first thermal treatment of the wood chips in a first thermal treatment device, which is designed to receive VOC-containing waste gases; cleaning the wood chips in a washing device; a second thermal treatment of the wood chips in a second thermal treatment device, which is designed to receive and separate VOC-containing waste gases; digesting the wood chips in a digester, which is designed to receive and separate VOC-containing waste gases; and crushing the wood chips in a refiner, which is designed to separate VOC-containing waste gases. This allows for an efficient, and thus energy-optimised or environmentally friendly and therefore also cost-optimised reduction of volatile organic compounds from wood chips.
