Engineering360: "Researchers develop new plastic that is repeatedly recyclable"

This is not new, more chemical recycling, but --

does not compare mechanical recycling with chemical,

does not deal with collection/separation,

nor with energy losses (breaking atom-atom bonds takes energy),

nor the chemical precursors of PDK and their enviro and financial costs,

nor compare full breakdown to monomers with breakdown to liquids (pyrolysis),

nor the justification/sanctification of recycling without dealing with numbers and options to use less.

Their advance may be the use of acids to break chains, but their problem is to show users that this new plastic can do the jobs of many old ones at acceptable cost.
