Electronics printed on flexible media are omnipresent in our connected world. Very often, electronics are printed on plastic, which makes its recycling difficult or even impossible. In 2019, 53.6 Mt of electronic and electrical waste were produced worldwide and only 17.4 % of this waste was properly collected and recycled . From this electronic and electrical waste, printed circuits boards (PCBs) concentrate the majority of precious metals (Au, Ag, Pd, Cu, etc…). However, the epoxy resin-based support largely used makes the recycling and extraction of these metals difficult. In this context, the European CircEL-Paper project arose. The resin-based support is replaced by a paper support. Therefore, the objective is to adapt the recycling lines currently used for paper to electronics printed on paper substrates in order to maximize the recovery of cellulosic fibers (accepts fractions) and conductive inks (rejects fraction).
