Abstract In this study, the VOC emissions from a self-bonded coriander board originating from a coriander biorefinery, were investigated. These emissions mainly result from the presence of essential oil in the manufactured materials. Firstly, an extensive analysis of the essential oil obtained from French coriander fruits showed the presence of linalool as the major component (72%), with an absolute concentration in the essential oil of 412 g/L. A characterization of the enantiomeric distribution of linalool, which is important in terms of its bioactivity, resulted in an enantiomeric excess of (S)-linalool of 77%. Further, the presence of this volatile oil in the coriander boards was confirmed through identification of the terpenoid compounds in the VOC emission profile. The area specific emission rate of linalool and camphor was determined at 125 and 25 μg m−2 h−1, respectively, at 25 °C and 50% RH, while their emission was found to increase by a factor of 3 with an increase in temperature of 10 °C. The renewable self-bonded boards could thus present potentially interesting alternatives for less sustainable materials in the construction or agricultural industry, where they could provide a significant added value in terms of indoor air quality or storage of food and agricultural products.
