Fibreboards were made from Scots pine (Pinus sylvestris [L.]) using the thermo-mechanical (TMP) and chemo-thermomechanical pulping (CTMP). The boards were made without binders (insulation boards) and with aminoplastic resins as a binder (medium density fibreboards (MDF)). The results of a joint research work, carried out by the University of Göttingen and the Fraunhofer-Institute for Wood Research (WKI), Braunschweig, revealed that the pulping techniques (TMP and CTMP) have a significant influence on the chemical composition and the emission level of volatile organic compounds (VOC) from fibres and binderless fibreboards. Binderless fibreboards made from TMP release more aliphatic aldehyds and ketones compared to those made from CTMP. However, the emission of acetic acid was, in general, much higher from CTMP and binderless fibreboards made therefrom. Moreover, the results indicate that volatile organic compounds generated during the pulping process (TMP and CTMP) could interact with the binders used for making medium density fibreboards (MDF) affecting both the level of VOC emission and the chemical composition of the released volatile organic compounds (VOC).
