Glycans represent a family of substance so far underestimated for material use. Primarily, they can be obtained from by extraction from carbohydrate-rich or lignocellulosic material streams.

The great challenges are the cost efficiency and resource requirements of currently available technologies. This concerns the extraction and purification for recovery on the one hand, and the further processing on the other hand, since chemical modifications are necessary for material use.

The project consortium is developing glycan-based binders for packaging materials. The size of the glycans is of crucial importance for this - three different processes are being compared. Ultrafiltration and industrial functionalization processes for polysaccharides are being adapted for processing. The application test is carried out in proven formulations of paints and varnishes.
