I believe it's still working on lignin as an opportunity. In this region, ABC3D, Advanced BioCarbon 3D, was researching opportunities of extracting lignin from wood chips to create a biodegradable plastic. I haven't heard what their latest opportunities are there, but through the pulp and paper process, lignin is extracted and can be utilized as a biodegradable polymer.
I'm not sure where it's at right now. Oftentimes, big industry gets really busy and the opportunities for applied research are put on the shelf.
