Avantium N.V, a leading technology company in renewable chemistry, announces that its subsidiary Avantium Renewable Polymers has granted leading wood modification company Kebony the right to use its patented technologies related to humins, as well as the right to file additional patents in the application area.
Humins are a valuable side stream from Avantium’s process to produce FDCA (furandicarboxylic acid), the key building block for the novel polyester PEF (polyethylene furanoate).
With these license rights, Kebony has the potential to successfully commercialise wood modified with a mix of humins and furfuryl alcohol. This may pave the way for a further collaboration between Avantium and Kebony and the commercialisation of humins from Avantium’s FDCA flagship plant which is planned to start up in 2023.
Humins are a novel plant-based raw material with a unique polymeric structure similar to caramelised sugar, and a range of diverse chemical functionalities. One such functionality involves mixing humins with bio-based furfuryl alcohol to modify soft woods in order to considerably increase their durability.
Avantium was granted a patent on a resin that is a mix of humins and furfuryl alcohol in 2015. Kebony successfully tested this resin and joined the PEFerence consortium as a partner to further develop applications of humins for wood modification. PEFerence is a consortium of organisations under the Horizon 2020 EU subsidy program aiming to replace a significant share of fossil-based polyesters with PEF.
Avantium has now agreed to grant Kebony a license to its humin related patents. Bart Langius, Commercial Director of Avantium Renewable Polymers, comments: “We are pleased with our collaboration with Kebony on humins, which we consider a valuable side stream from our PEF process. With Kebony, we share a common goal to replace fossil-based chemicals and materials with renewable alternatives.”
Norman Willemsen, CEO of Kebony, says: “We are thrilled that Avantium have granted us a license for the patented humin compositions and related manufacturing process. We believe that humins have potential as a valuable feedstock for wood modification. We look forward to continuing and expanding our partnership with Avantium in the coming years.”
