Burying plant waste removes CO2 from the air. But can it scale?
Graphyte will remove 15K metric tons of CO2 this year...notably more carbon-removal capacity than the largest existing DAC projects.

CASTING THE
CARBON FUTURE
Introducing the world’s first and only carbon dioxide removal solution that is permanent, affordable, and immediately scalable.
PERMANENT
We can remove CO2 for 1,000+ years.
AFFORDABLE
Levelized production costs at under $100/ton with minimal energy requirements.
SCALABLE
We can scale to remove billions of tons of carbon today.
OUR STORY
PRAGMATISM FOR A PLANETARY PROBLEM
Carbon removal is essential to fighting climate change. While 5 to 10 billion tons of carbon dioxide need to be removed from the atmosphere annually by 2050, today the world removes less than 0.001% of that. We need to do more.
Combining pragmatism and science, Graphyte has created a carbon removal solution that accelerates progress in the race against climate change. Carbon Casting seamlessly fuses nature's ability to capture carbon with the reliability and durability of engineering, setting a new standard for carbon dioxide removal.
After decades of working in the climate change space, we were committed to finding a better way to remove carbon. We knew that energy was critical. That’s why we started with the power of nature.
“CARBON CASTING LETS NATURE EFFICIENTLY DO THE WORK OF CAPTURING CO2, THEN LEVERAGES ENGINEERING TECHNIQUES TO STORE IT PERMANENTLY. IT’S A SOLUTION THAT CAN BE DONE ANYWHERE, THAT WILL CHANGE THE MARKET, AND MORE IMPORTANTLY, THAT WILL HELP SAVE THE PLANET.”
– BARCLAY ROGERS, FOUNDER AND CEO
THE SCIENCE
HARNESSING THE POWER OF NATURE TO SAVE IT
A key reason carbon removal can be expensive and hard to scale is high energy requirements, so we returned to nature’s proven, efficient process for capturing carbon from the atmosphere—photosynthesis.
Graphyte realized that the carbon captured in plant matter could be preserved by eliminating the causes of biomass decomposition—microbes and the water they depend on. Drying the biomass eliminates microbes, and impermeable barriers prevent water and gas from restarting the decomposition process.
CARBON CASTING
Carbon Casting is a new approach to carbon removal that takes readily available biomass—such as natural timber and crop residues—sterilizes and dries it into dense carbon blocks protected by a long-lasting polymer barrier, and then stores it in monitored, underground storage sites. It preserves nearly all the carbon stored in the biomass while also consuming little energy.
Combining photosynthesis with practical engineering, Graphyte’s Carbon Casting provides an immediate pathway for billions of tons of low-cost carbon removal with durability over 1,000 years.
OUR METHOD
RAISING THE CURTAIN ON CARBON CASTING
Carbon Casting is a new approach to carbon removal that leverages readily available biomass, such as residues from timber and farming operations. We dry and compress it into dense carbon blocks protected by an environmentally-safe, impermeable barrier, and then store these blocks in underground sites with state-of-the-art monitoring. Carbon Casting preserves nearly all the carbon captured in the biomass and consumes very little energy in the process.
Combining photosynthesis with practical engineering, Graphyte’s Carbon Casting technology provides an immediate pathway for billions of tons of low-cost, permanent carbon removal.
PERMANENT CARBON REMOVAL AT SCALE: OUR 5-STEP PROCESS
COLLECT
We use by-products of the timber and agriculture industries, which would otherwise be burned or left to decompose.
DRY
We dry this biomass, to eliminate microbes and the water they depend on, stopping decomposition.
CONDENSE
The inert biomass is condensed into dense blocks, enabling effective storage.
WRAP
Carbon blocks are protected by an environmentally-safe, impermeable barrier to ensure that decomposition does not restart.
STORE + MONITOR
Blocks are stored in state-of-the-art sites with sensors and tracers, enabling robust long-term monitoring. Storage sites can then be used as solar farms or working agricultural land.
OUR PARTNERS
With financial backing from Breakthrough Energy Ventures, we work with innovative companies around the world committed to building a low-carbon future.
