Multi-ply paper containing used paper fibers and additional fibers

A method for producing a paper comprising the following steps performed in a paper machine:

• applying a first web of a first fibrous material composition containing water and waste paper fibers relative to a dry mass on a first screen;
• applying a second web of a second fibrous material composition containing water, waste paper fibers in a maximum proportion of 80 wt %, relative to the dry mass, and additional fibers in the form of fibers other than waste paper fibers in a minimum proportion of 20 wt %, relative to the dry mass on a second screen, wherein the second fibrous material composition has a higher proportion of additional fibers than the first fibrous material composition;
• couching the first web and the second web formed on the first screen and the second screen to form an at least two-layer paper web;
• drying the at least two-layer paper web;
• and
• wherein the additional fibers contain a proportion of fibers from any of the following:
• of a cup plant (Silphium perfoliatum), of fibers obtained from fruits and/or the bark of trees of the baobab genus (Adansonia), of fibers obtained from plants of the genus Cannabis, and/or of fibers originating from a residue of biogas facilities.
