RE: RE: PLET More Advanced than LEC?...I'm no biochemist either, so I took your advice and googled "high quality lignin".
Half way down the first page I saw this link:
https://www.bioautocouncil.com/conferences/international-lignin-biochemicals.aspx
It's the home page of a conference held last November. It features the agenda of the two-day mid-week conference in Ontario. Running down the fairly short list of presenters, I noted LEC's COO presenting Lignol's technology as a solution to the industry's recurring problem of commercial practicality.
I didn't see ANY other public company sessions proffered except one from Germany; most presenters were academics.
I also checked out PLET. They have a website, I'll say that.
