It says "Leveraging the trace amounts of moisture in air, the broken-down PET is converted into monomers—the crucial building blocks for plastics. From there, the researchers envision the monomers could be recycled into new PET products or other, more valuable materials." I don't know if there's some enormous challenge hiding behind the word "envision", but I'm assuming it's a closed system until something useful comes out of the other end. The method just can't be a lot more expensive than to make the same thing/material from scratch or it's never going to gain traction.

Well let's truly hope that its not that much expensive
