How does one even begin to address concerns about toxicity with so many different chemicals? Go in order of concentration? Most to least likely to be biologically active based on models? Cluster them and evaluate the clusters?

Slowly make less every year, the goal of rohs, reach, etc. Then work to sequester/store/recycle/breakdown what we've already made in a responsible, economical, and non planet destroying way.

Depending on the stream (source) and chemistries there are ways to separate out plastics of concern (POCs) but they aren’t fully at scale yet depending on stream. It’s also very hard.

You go by separating valuable fractions out first.
