WOODCHEM® 2019 will take place in Nancy, France on 20, 21 and 22 November 2019. The conference is organised by the French clusters Fibres Energivie and Industries Agro Ressources with the support of Xylofutur and Cosmetic Valley clusters. As in previous years (Epinal 2009, Strasbourg 2011, Nancy 2013 and 2017), our scientific and organising committees are committed to organising a rewarding conference for all participants. It is with great pleasure that we invite authors to submit their presentations and papers on the conference topics and to participate in WOODCHEM® 2019.
