Sorry to get to this question late. There is some good discussion below on the possibilities of bio-based and nature-based solutions. We see bio-based solutions as having a great advantage in the short term since the feedstocks are concentrated & the collection is fairly straightforward. But we believe that these technologies may have a hard time getting to bulk scale as land & logistics become a concern.

Most likely, industrial/engineered solutions and nature-based/bio-based/ocean-based solutions will need several years to evaluate which paths are most viable. We wish everyone luck in this challenge for the world's sake!
