Humins as promising material for producing sustainable polyssacharide-derived building materials
The chemical industry is pushed by public opinion and brand owners to a more sustainable resource utilization such as changing from fossil feedstocks to biomass which is a renewable resource. The major component of biomass are polysaccharides, so to drive the competitive utilization of (2nd generation) polysaccharides towards non-food applications and thereby creating biorefinery supply chains it is essential that all (side-)products are valorized at maximal added value. Nowadays biobased building materials are used in various fields and for a wide range of applications such as polymers, fillers, coatings, adhesives, impregnation materials or high performance composites. This work focuses on humins, a biomacromolecular by-product of a FDCA biorefinery. Humins are obtained by acidic treatment of polysaccharides and show very interesting potential as a reactive, semi-ductile thermoset matrix to impregnate cellulosic fibers. These encouraging results assure an important future for humins as economic green matrix for the production of textile composite and wood impregnation for instances.
