“…Another strategy widely employed for upcycling is selective decomposition of polymer into monomeric units or reactive intermediates through physicochemical treatment. Thermal hydrolysis is a widely employed depolymerization technique for monomer synthesis ( Panda et al, 2010 ; Ryan et al, 2021 ). But the technique suffers from two major challenges, e.g., low heat transfer and low flow diffusion capacities which restrict the thermal conversion of plastics.…”
