Inter Earth

Perth WA, Australia

Partners with nature to tackle our biggest environmental challenge.

InterEarth is uses photosynthesis to capture CO2 from the atmosphere. They grow trees, harvest their above ground biomass and put that biomass, and its contained carbon, back underground.
Country: Australia
Status: In development
Type: Biomass burial

Loam

Mildura VIC, Australia

Harnessing the power of microbes into sustainable solutions.

Loam works with 4.5 billion years of evolution to solve the climate crisis. Microbes have changed the composition of our atmosphere through earth’s history. At Loam, we are ensuring these organisms can do it again. Through a better understanding of how microbes influence the carbon cycle, we can create new planetary-scale opportunities for carbon sequestration and improve agricultural productivity.
