Did we watch different interviews? Can you please share the quote where Ian Grant said they're "still happy collaborating with PYR"? Timestamp in the video as well?

Scraped from the Pyro part of the interview starting at approximately the 45:50 mark after mentioning the R&D delays:

Still something we are excited about; extending ways at the point where demand exceeds supply of post consumer glass, findings ways to extend the life of that post consumer glass and get more volume for it. So some really exciting projects we have both in house and with Pyrogenesis on that side of things.

We can lay that to rest; Pyro also confirmed this effort is ongoing in the recent CC.
