This biocarbon serves multiple applications, including as an alternative to petroleum-derived carbon black, a substitute for coal in steel production, and a replacement for bitumen in infrastructure projects, contributing to carbon sequestration.

The company's revenue model includes partnerships with organizations that produce or manage waste biomass, as well as potential subscription agreements for ongoing supply contracts for their biocarbon products. These transactions facilitate the conversion of landfill waste into valuable resources, creating mutual economic benefits. Pricing structures for Carba's biocarbon products reflect the value added through their innovative processing technology, positioning them competitively against traditional carbon sources. Revenue growth may be further supported by strategic collaborations with companies focused on carbon removal and environmental sustainability, enhancing the overall market appeal of Carba’s offerings.In December 2025, Carba, Inc. raised USD 6 mn in venture funding to enhance its product offerings and expand its market reach. The company plans to develop new biocarbon products tailored for various industrial applications and aims to enter new geographic markets in Europe and Asia by 2026.
