> grapevine waste is a concern, and why it’s a particularly effective source of cellulose.

We have markets and prices. If cellulose became scarce enough that the cheapest source for it became agricultural waste, we wouldn't need the government to fund research into an extraction process. Industry would be all over it on its own.

State funding for research is there to solve the problem of industry incentives being aligned against foundational, long term research. What we're looking at here isn't anything like that. It's just one more organic extraction process, another entry in a long tradition of such things.
