Carba converts waste biomass into stable, high-yield biocarbon using proprietary modular reactors. This biocarbon serves as an input for industrial materials and enables permanent carbon removal through landfill burial. The process also provides environmental co-benefits by filtering toxic substances like PFAS, lead, and mercury from leachates.

Problem
The increasing concentration of atmospheric carbon dioxide necessitates effective and scalable carbon dioxide removal (CDR) solutions to mitigate climate change. Many existing CDR methods are energy-intensive, costly, or lack the permanence required for long-term carbon sequestration. There is a need for a cost-effective and verifiable CDR technology that can utilize readily available waste biomass.
Solution
Carba employs Anoxic Biochar Burial™ (ABB), a proprietary technology that transforms low-value natural waste into high-yield solid carbon. This carbon can then be permanently sequestered underground in anoxic environments, preventing degradation and ensuring long-term storage for over a thousand years. The ABB process utilizes a patented reactor designed for energy efficiency and minimal material waste. Carba's solution offers a measurable, traceable, and permanent approach to carbon dioxide removal, providing a sustainable alternative to traditional methods. The resulting high-yield carbon output can also be repurposed for carbon-neutral products, creating a closed-loop system.
Target Audience
Carba's primary customers include organizations seeking to offset their carbon footprint through verifiable and permanent carbon removal, biomass partners looking for sustainable waste management solutions, and companies interested in utilizing carbon-neutral products made from sequestered carbon.
