Lignin is a framework substance that is contained in wood along with cellulose and other components. It causes the additional stiffening of the fibers there. In the paper is an undesirable addition that causes the paper to yellow quickly. During pulp production, it is largely chemically separated from the cellulose.

Our cardboard is made from 100% mixed waste paper grade 1.02 raw material. Due to this use of raw materials, we can not guarantee the ingredients. Thus, we cannot exclude the presence of trace elements of lignin within our paperboard.

Nonylphenol is a precursor for nonylphenol ethoxylates (NPEs), the most important subgroup of alkylphenol ethoxylates (APEs), which are mainly used as detergent-active substances (surfactants). In the environment, NPEs revert to toxic nonylphenol. APEs can be found in pesticides, detergents and disinfectants as well as in food packaging, e.g. PVC films. They are also present in printing inks and wall paints or chemicals used in crude oil production. They are also used in the production of plastics, textiles, leather and paper.

Nonylphenols and nonylphenol ethoxylates are substances that can be used specifically in auxiliaries (cleaning agents).

We hereby confirm that both substances are not contained in any of the auxiliary materials (cleaning agents) that are important for our production. Thus, we can exclude a transfer of the substances to our cardboards.
