Abstract

A method for rendering a substrate hydrophobic while maintaining its biodegradability includes treating the substrate with a reactive silane such that the reactive silane forms a resin in the interstitial spaces of the substrate. The method parameters are controlled such that the resulting hydrophobic cellulosic substrate is compostable.
