Mechanical Trees Capture CO2 for Reuse

Mechanical Trees Capture CO2 for Reuse
Mechanical trees able to capture carbon dioxide could reduce pollution while also collecting the gas for reuse.

Developed by a team from Arizona State University, the ‘mechanical trees’ consist of a column made up of stacked discs of sorbent, which will capture CO2 when exposed to air. The full discs are then lowered into a container, where the CO2 is collected for use and the now-empty discs redeployed.

Twelve trees could remove one metric ton of CO2 each day for less than $100 a ton, which is the lowest in the industry—a key advantage to the technology and its potential impact.
