How do you track emerging materials in the specialty chemicals space?

Honestly the best filter I've found is tracking patent filings through Espacenet or Derwent alongside startup funding rounds — if a bio-based material is seeing both, it's usually past the hype stage. I also follow a short list of procurement leads at Evonik, BASF, and a few mid-tier compounders on LinkedIn since they signal real adoption faster than any analyst report. Trade shows like specialty chemicals tracks at ICIS events are still underrated for separating lab-stage from commercial-ready.
