"Right now, there is no biodegradable, sustainable substrate for deploying carbon dioxide-sorbent materials"

Correct me if I'm wrong, but growing vegetation in and of itself is a biodegradable, sustainable, carbon dioxide-sorbent process. Maybe we should look at fast growing, strong plants to harvest for building materials. Also, plant growth is solar powered...so that's neat.

The delignification process they describe sounds like the first steps of paper making, which isn't a pretty process when we're talking about wood prep and digestion. After all that, is this product going to be a net carbon sink? I really doubt it.

Can't we just genetically engineer bamboo for better viability?
