TREBODUR is bound by the natural amount of proteins in brewers' spent grain. No additional binders are added. Brewers' spent grains are the residues that accumulate from barley malt during the process of lautering while producing beer. When used for all kinds of packaging products, TREBODUR can substitute customary materials such as paper and plastics. As it is compostable, it is, for instance, attractive to huge outdoor events, retail or marketing. At the end of the lifecycle, products made from TREBODUR can be easily composted without residues. Due to its utterly natural origin, the material decays quickly, even on garden compost heaps. Furthermore, it is possible to add substances like minerals, ashes or even plant seeds to the material to supply the soil.
