摘要

The invention concerns a method for making a composition for producing corks, characterised in that it consists of the following steps: a) grinding cork sheets into small size granules; b) decomposing said granules into granules with high lignin content and granules with high suberin content; c) separating the granules rich in lignin from the granules rich in suberin so as to retain only the granules rich in suberin. The invention also concerns a composition containing cork granules rich in suberin and a cork comprising such a composition.
