Carbon Cell

we are on a mission to make polystyrene waste a thing of the past. 

Carbon Cell is dedicated to providing a sustainable alternative to traditional polymer-based foams. Our high-performance expandable foam is fully compostable and locks in carbon for centuries.

why carbon cell

Carbon Cell's patent pending (2402238.6) revolutionary technology makes it an ideal choice for anyone looking for an eco-friendly alternative to traditional polymer-based foams. 


Carbon Negative

Because it's made with biochar, Carbon Cell is carbon-negative. This means that it removes more CO2 from the atmosphere than it requires to make.



Carbon Cell boasts a competitive thermal conductivity and is three times stronger than EPS and other bio-based alternatives. It also performs well under fire and has a comparable sound insulation to EPS foam.


Flexible Manufacturing

Our flexible manufacturing process allows us to rapidly form our foam in different customizable geometries. This allows Carbon Cell to be used in a wide variety of applications, from packaging to construction.


Fully Compostable

Carbon Cell has a renewable supply chain, and is compostable within home composting conditions!

Biochar is the key ingredient that gives Carbon Cell its unique properties.

It’s basically a fancy kind of charcoal made in a process called pyrolysis. During this process, organic biomass is transformed at high temperatures in the absence of oxygen.


The resultant material is carbon negative. In fact, each tonne of biochar can lock in up to 2.1 tonnes of CO2e [1]

And it can be made from waste streams like potato peels or even textile waste.



We are a team of surfers and sailors, designers and engineers, and we are sick of seeing toxic trash everywhere.


We have over 25 years of combined experience in business and an unrelenting commitment to sustainability. We have worked in diverse fields, such as civil engineering, product design, bio-materials, and brand strategy, and expertise in deploying sustainable design methods, such as life cycle analysis and circular design. 

We met while studying a double master's in Innovation Design Engineering (MSc/MA) between Imperial College London and the Royal College of Arts and came together as a team due to our unrelenting passion for  on our passion for sustainability.

We are also backed by a talented board of advisors with world-class expertise in engineering, sustainability, and material science. And have participated in the following prestigious accelerators and competitions:
