The Newest Airline Climate Solution? Burying Sawdust

Ed Ballard and Amrith Ramkumar of The Wall Street Journal report on American Airlines’ investment in sawdust.

The C3 Take
  • American Airlines is buying carbon offsets from Graphyte, a startup that turns agriculture waste like sawdust into shoebox-sized bricks that trap CO2.
  • Whereas other carbon offsets like direct air capture can cost companies $675 per metric ton of CO2 removed, Graphyte is charging American Airlines only $100 per ton.
  • Graphyte’s solution is indicative of the role that private sector innovation will play in reducing global emissions.

“Graphyte’s first project in Pine Bluff, Ark., collects waste from two timber mills and a rice-milling operation. The company aims to start manufacturing its biomass bricks in January and burying them in July. By then, it hopes to be making roughly 140 pallets of blocks a day, enough to store 50,000 metric tons of carbon annually.”
