Reading their plans: https://newscenter.lbl.gov/2019/05/06/r ... nside-out/, I would assume they know what they are talking about, but yeah cost is always in question. They could also by hyping it for .. reasons, I guess.

However, monomer recovery is often costly, incompatible with complex mixtures and energy-intensive. Here, we show that next-generation plastics—polymerized using dynamic covalent diketoenamine bonds —allow the recovery of monomers from common additives, even in mixed waste streams. Poly(diketoenamine)s ‘click’ together from a wide variety of triketones and aromatic or aliphatic amines, yielding only water as a by-product.

I dunno wtf this means, with regard to cost. dynamic covalent diketoenamine bonds .. ok

As a side note or a joke perhaps .. 50 years ago we would read something like

Researchers have designed a new plastic that can be used in a variety of applications from water bottles, to shopping bags and straws.


yay for science, what could go wrong?! lol
