Beschreibung
Zusammenfassung:	The present invention relates to an integrated method for producing cellulose and at least one low-molecular-weight reusable material, in which a starting material containing lignocellulose is provided and subjected to a decomposition with a processing medium. A fraction enriched with cellulose and a fraction depleted of cellulose is then isolated from the decomposition material, the depleted fraction of cellulose being subjected to a treatment during which at least one low-molecular-weight reusable material is obtained.
