An integrated method for processing and using guayule plants

摘要

The present invention relates to an integrated process for processing and utilizing every part of the guayule plant (Parthenium argnetatum) which comprises the following steps in sequence: separating the stem and branches from the leaves of said plant with a mechanical treatment; treating the leaves to produce waxes and essential oils, and a fraction containing cellulose, hemicellulose (carbohydrates) and, to a minor extent, salts, organic compounds and lignin; extracting from the stem and branches a liquid phase, so forming a first solid woody residue, indicated with bagasse in the present text; treating said first solid woody residue to prepare sugars, resin, rubber and lignin.
