Company Overview

Carbon Cell is a materials science company that has developed a carbon-negative, plastic-free foam to replace traditional polymer-based foams like expanded polystyrene (EPS). The company's patent-pending technology utilizes biochar, a form of charcoal made from waste biomass, and natural polymers to create a high-performance, compostable, and lightweight foam. This material is designed for various sectors, including packaging, construction, and insulation. By using biochar, the company's product sequesters more carbon than is emitted during its production. Carbon Cell aims to provide a sustainable, drop-in replacement for plastics, addressing the environmental impact of materials that are difficult to recycle.
