carbon

Produced with minimal carbon emissions, Partanna is a building material that removes carbon from the atmosphere.

Blue Carbon is carbon absorbed by our seas. Green Carbon is carbon absorbed by our plants. Partanna a pioneer for Gray Carbon: carbon absorbed by building materials.

The world's first carbon negative community

We’re building the first carbon negative housing community in The Bahamas, laying the foundations for the future we need to build.

Vision

Building a
world that
breathes

The world we continue to build is slowly suffocating us. Global CO2 emissions are at their highest level in history. Construction accounts for 38% of them. 9% are from the cement industry alone. And we’ve lost one third of the earth’s lungs in deforestation.

It’s time for the problem to become part of the solution. That’s Partanna.

Partanna is a building material created with minimal carbon emissions that absorbs carbon from our atmosphere. We’re leading the way for carbon removal and carbon avoidance.

Our nature-positive technology is the solution that communities most vulnerable to climate change deserve.

a new
Urban Era

Partanna doesn’t just change construction. It reimagines what the built environment means.

Where traditional urban environments go up against our ecosystem, Partanna is part of it. It’s a solution that revolutionizes how we think about urban spaces and transforms cities into a Gray Carbon vertical.

Building a world that breathes starts with our project to build the world’s first carbon negative community.

Beyond capture
and sequestration

Carbon sequestration is expensive, energy-intensive and unproven at scale. Partanna is different. It avoids energy-intensive carbon capturing and emissions from carbon sequestration. It also absorbs carbon with zero emissions at a much faster carbonation rate through direct air capture.

Sustainable

We have created a truly circular economy.

Partanna does not require intense heating and doesn’t release CO₂ as it cures.

Made from sea brine and recycled steel byproducts.

Production requires no intense heating to make raw materials, nearly eliminating any harmful CO₂ emissions.

Partanna is locally sourced and cost-effective.

Raw materials can easily be obtained from brine — available all over the world in growing supplies.

Efficiencies created in the building process through single panel construction.

By being processed at room temperature, Partanna avoids particulate emissions that lead to 10 million+ deaths each year.

Partanna houses can withstand hurricane force winds that destroy traditional CMU constructed homes, and as Partanna is made with brine, it gets stronger through exposure to saltwater.

Through tokenizing the carbon credits we obtain, we are changing the model for home ownership, providing affordability and a home that will last.

We’re developing the world’s first carbon negative housing community. Each home will be fully hurricane-proof.

This is the first full Partanna development and The Bahamas is the best place to start.

Home to one of our founders, The Bahamas is one of the countries that suffers the consequences of our suffocating world.

It’s a low-lying nation investing into a market of clean, resilient building solutions and is a prime location for saltwater brine: an essential piece of our product. The impact of Partanna is bigger than our product. By using mostly locally sourced materials and training local labor, Partanna brings industry and self-reliance to areas of the island with the greatest need.

We have full approval and support from the Prime Minister of the Bahamas, the Rt. Honorable Philip Davis, a recognized leader at the forefront of the global climate change movement. Together, we’re ready to make a change.

About us

Our founders have both experienced great loss associated with climate change.  

Growing up in the Bahamas, tropical storms were a constant in the childhood of co-founder Rick Fox.  With each storm increasingly stronger, he witnessed first-hand the devastating housing crisis that emerged in the wake of Hurricane Dorian. In California, with more frequent and widespread wildfires, co-founder Sam Marshall saw his home seriously damaged in the Malibu Wolsey Fire. It was in the height of the pandemic, when the pair met and shared their stories.  

With the pandemic exposing the rapid impact of tragedy on a global scale, they immediately realized the same dramatic impact of climate change.  Refusing defeat and inspired to create change, Rick and Sam turned the power of that impact around for the good.  

For almost 2 years, Sam and a team of scientists worked on the formula.  Then came an opportunity in Rick’s home country for the new technology to be applied in the front lines of the war on climate change in the Bahamas.  They knew that if they could successfully apply the innovation in one area of need, it could be applied to other regions and countries around the world.  

We are honored and grateful for the Bahamas' desire to rebuild with fierce tenacity and climate intelligence, under the guidance of Prime Minister Davis, utilizing the power of Partanna as an integral part of its solutions, and as the foundation for Partanna’s beginnings.
