Nowadays, the idea of a circular economy has been the subject of industries all around the world. That is because the benefits of this method are untold, not only in addressing environmental issues but also in improving productive processes and thus bringing profitability to the companies. Believing in this concept, BP Security, a Blendpaper Brazil banknote and security paper brand, saw an opportunity in a niche that is now seen as a problem in the banknote market: currency paper waste.

A highlighted important factor is that banknote waste takes a longer time to decompose compared to ordinary paper waste. This happens because the banknote paper receives a chemical treatment that offers an wet resistance. The Blendpaper team studied the best way to permeate the wet resistance in these papers, the highest challenge to the transformation of currency paper waste, with the technique of repulping. Therefore, besides producing new fine papers and papers for printing/writing, is possible to expand and spread this new technology to make it possible to establish more partnerships with various mints all around the world and therefore transform this by-product into banknote-paper or security paper, closing the loop on this material.
