) which comprises the following steps in sequence: separating the stem and branches (
3
) from the leaves (
2
) of said plant with a mechanical treatment (
1
); treating the leaves (
100
) to produce waxes and essential oils (
102
), and a fraction (
101
) containing cellulose, hemicellulose (carbohydrates) and, to a minor extent, salts, organic compounds and lignin; extracting (
200
) from the stem and branches a liquid phase (
4
), so forming a first solid woody residue (
5
), indicated with bagasse in the present text; treating said first solid woody residue (
5
) to prepare sugars, resin, rubber and lignin.
