The paper cycle is considered a pioneer for a successful circular economy. In Germany, the recycling rate for paper, cardboard and paperboard is 85% (as of 2023). Together with partners from industry and associations, we are researching how the recycling rate can be further increased and how recovered paper can be used as efficiently as possible in the production of new goods. This begins with the most accurate measurement-based and practical assessment of the composition and quality possible. The findings from this research are directly incorporated into PTS's own product developments, such as DOMAS, PaperBaleSensor, RePEye, or as Software-as-a-Service, and help us to advise you.

In our research work, we also consider questions regarding the actual environmental compatibility of individual developments.

The basis for the recyclability of a paper product is laid already during the design phase and must take into account consumer behavior, possible contamination, sortability and technical recyclability. In the paper mill, it is important to ensure that recovered paper is processed as efficiently as possible into a pulp of consistent quality. By using innovative sensor technology, we constantly rethink and further develop energy requirements, yield, breakage minimization, the identification of disruptive contaminants and troubleshooting under changing technical conditions and required environmental standards into innovations for the paper industry.

Assessing the recyclability of paper products also means researching how the barrier used affects the collection, sorting and technical recyclability of the product. However, a suitable barrier must first be selected which prevents the penetration and transfer of undesirable substances while complying with legal standards. Therefore, we develop suitable methods that can be used in research and in operational practice.
