Common preparation of lignocellulosic feedstock and a product containing cellulose but free from lignin

A method for providing a treated cellulose-comprising mixed starting material for forming are generated cellulosic molded body, wherein the method comprises:

• providing a first starting material which comprises a lignocellulosic raw material;
• providing a second starting material which comprises a cellulose-containing lignin-free product,
• wherein the cellulose-containing lignin-free product comprises textiles;
• mixing the first starting material and the second starting material to a mixed starting material;
• and
• at least partially commonly treating the first starting material and the second starting material for obtaining a treated cellulose-comprising mixed pulp;
• wherein providing the second starting material comprises at least one of the following features:
• preparing the cellulose-containing lignin-free product;
• adjusting a substantially predefined composition, wherein adjusting comprises:
• selectively enriching at least one composition component, and/or
• selectively depleting at least one composition component.
