Description
Onofrio Losito and co-authors published a chemistry study in 2024 on catalysts that break down polycarbonate plastic for recycling. The plastic is strong and heat resistant, which makes waste handling hard. Chemical recycling splits it back into building blocks, usually without catalysts. The team tested silica-based catalysts with a core-shell build, picked for strength and reuse.
Samples were treated under varied heat and time with oxygen or nitrogen partners. The core-shell catalyst worked well, giving up to three-quarters yield in one reaction type, with pure building blocks as output. Those blocks can feed new polycarbonate making. The authors present the method as a greener route for this plastic's waste.
