Since plastic packaging accounts for a large fraction of plastic waste, the demand for environmentally friendly packaging options is increasing. One material that is becoming more and more popular as a sustainable alternative to plastic is paper.

These additives contaminate the paper, complicate the recycling process, and reduce the quality of the recycled material. This poses a significant challenge to the otherwise established and efficient paper recycling process.
