taking plant waste from timber companies and farmers, drying it, compressing it, and wrapping it “into Lego-like bricks,” and storing it 10 feet underground.
So it’s effectively the astronaut ice cream version permafrost?
Immediately I wonder how much the process of transport -> drying -> compressing, wrapping, transporting, and storing + storage site prep and maintenance eats into savings.
Yeah, that’s what it sounds like. I do wonder if 10 feet is deep enough to prevent decomposition in the long term. I seems like converting the plant material to biochar would be a more stable form to trap the carbon in.

I think the key aspect here is that all of these steps are easier to decarbonize than the aviation (difficult) and cement production (almost impossible) processes these bricks are intended to offset.
