ScholarlyArticle: "Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production" (2026) https://advanced.onlinelibrary.wiley.com/doi/10.1002/aenm.20...

Lignin-Vitrimer can be recycled with hot acetic acid.

If hot acetic acid can be made from plastic waste, I think that almost solves the additional recycling stream problem for Lignin-Vitrimer.

There are also processes for hydrogen from plastic and plastic to plastic with just hydrogen

In case the article is not clear enough, the idea is to use the acetic acid as a insume of other chemical process, not to produce food (vinegar).
