Using direct air capture technology, Heirloom enhances the carbon mineralisation process. Their technology works by speeding up the rate at which naturally occurring CO2 is captured instead of using more energy-intensive fans that work by drawing air in.

Using semi-truck tailpipes that capture CO2 as they drive, Remora transports that CO2 for long-term storage.

Using plate waste which is converted to a stable carbon-rich liquid, Charm safely stores CO2 deep underground where it is out of reach of wildfires and soil erosion.
