Bill Gates-Backed Startup to Use Old Wood to Remove Carbon From the Air
“Carbon casting” is a unique form of CO2 removal technology that could be a key to reversing the worst effects of climate change.
Graphyte takes waste biomass like discarded wood residue or rice hulls, dries and sterilizes it to prevent decomposition.

“It’s important to understand that carbon removal is not an excuse to keep emitting, or to slow down our transition to a clean energy economy — we need to keep innovating as fast as we can,” Gates wrote in his firm’s “State of the Transition 2023” report, released today. “But it’s become clear that carbon removal will be a necessary tool to have in our toolkit.”
