<p>In order for humanity to progress and thrive, we must appreciate Earth as the spaceship it is. Our atmosphere, and the diverse ecosystems it sustains, are our vital life support system against an otherwise inhospitable space. Equipped with an astronaut mindset, we treat our natural resources as precious and human kindness as essential.</p>
<p>Arbor is developing a scalable and low-cost approach to reverse humanity’s climate footprint, leveraging advanced rocket engine technology and Earth’s own natural rhythms. We are designing, manufacturing, and operating systems that will restore balance to the planet and set the foundation for a global circular economy. Our technology converts waste into clean energy and fresh water, while permanently removing CO2 from the atmosphere. We're using the same technology developed to get humans off the Earth to now help us save it.</p>

Transforming waste into clean energy and fresh water while permanently removing CO2 from the atmosphere.

<div><b style="font-size:18px;">About Us: </b></div><div>At Arbor, we are  developing a scalable and low-cost approach to Biomass Carbon Removal and Storage (BiCRS) based on modern rocket engine technology. BiCRS is a carbon dioxide removal (CDR) approach that uses biomass to remove CO₂ from the atmosphere and store it permanently underground, while ensuring food security, rural livelihoods, and biodiversity are not affected. Our team brings together a deep passion for science, technology, community, and strategy required to make low-cost, high-quality carbon removal a reality. Our modular technology leverages compact gasification, oxy-combustion with a supercritical CO₂ cycle, and high-pressure turbo-expansion to convert abundant forestry waste biomass into clean electricity, water, and high-purity CO2, capturing and sequestering all emissions from the process. </div><div>Two years into our journey we: assembled a world-class team of engineers and scientists, raised over $30M from top deeptech investors, pre-sold our first 2000 tons of carbon removal, and are designing our first plant to demonstrate our novel technology capable of generating carbon-negative energy.</div><div><br></div><div><b style="font-size:18px;">Our Values: </b></div><div><span style="font-size:11pt;">Foster Planetary Partnership, Lead with Love, and Explore the Uncharted.
