D5.2 End of Life report - EXECUTIVE SUMMARY

Within the End-of-life study (task 5.1.2.), recycling technologies to enhance the circularity of MADRAS demo devices have been outlined and key steps developed in the laboratory. The proposed recycling strategies are based on off-the-shelf proven recycling technologies and present as a common key step in the recovery of silver through a new and eco-friendly leaching process developed on a lab scale. The newly developed method allows the recovery of nearly all silver metal in the form of silver (I) acetate, a useful starting material in the preparation of conductive inks used in flexible circuits of organic and large-area electronics (OLAEs). The developed process does not use toxic reagents or solvents and affords silver (I) acetate in high purity (>99%). The study also highlights the benefits of using silver (I) acetate instead of silver (I) nitrate in the production of conductive inks and summarizes manufacturing conditions as inputs for LCA assessments.
