Yeah. Recycling is a long and problematic chain, and no magical miracle chemistry chain-link could change that. OTOH, there's a lot of plastic that is discarded at larger scales (vs. Chris & Pat drop their empty bottles into bins), and a really good chemistry might make recycling a far better choice in those scenarios. And much of the world does not have well-run (especially long-term) landfills to put trash in. And there's a morale effect, too - if we quite reasonably can recycle some common types of plastics, that injects a bit of hopeful news into the generally miserable plastics recycling situation.
