Rethinking paper
A report by Finnjo Gräbke
On Friday, 7 March 2025, we had the opportunity to visit the Steinbeis paper mill in Glückstadt and gain an exciting insight into sustainable paper production. We were welcomed on site by Jan, who gave us a brief introduction to the history, structure and sustainable production of the company.
Our tour of the production halls then began. We first went to the sorting hall, where the waste paper delivered is separated from foreign materials such as plastic or cardboard. We then moved on to the hall where the sorted waste paper is processed. Here, the waste paper is dissolved in large drums with water and other additives so that the fibres separate from each other. The so-called deinking process uses soap and air to remove printing inks and impurities, which brightens the fibres without using aggressive bleach.
