Zerotwelve provides Z12™, a biochar‑based cement additive that can replace Portland cement in any concrete mix. The drop‑in product sequesters more CO₂ than it emits, creating carbon‑negative concrete while improving strength, durability, and workability, and enables users to access carbon‑credit incentives.

Problem
Concrete production, specifically cement manufacturing, generates roughly 8% of global CO₂ emissions, making the construction sector a major source of greenhouse gases. This high carbon footprint conflicts with increasing regulatory pressure and market demand for low‑carbon building materials, limiting the industry's ability to meet climate targets.
Solution
Zerotwelve offers Z12™, a drop‑in cement replacement that captures and locks carbon within the concrete matrix. The product uses biochar‑based technology to sequester CO₂, resulting in a carbon‑negative material that can be mixed with existing concrete recipes without new equipment. Z12™ also improves key performance metrics such as compressive strength, durability, and workability, allowing builders to meet or exceed traditional specifications while reducing embodied emissions. By integrating seamlessly into standard concrete production, Z12™ enables immediate adoption across the supply chain and opens access to emerging carbon‑credit markets, providing both environmental and financial incentives.
Target Audience
Primary customers are concrete manufacturers, construction firms, and developers seeking to meet sustainability standards and reduce the carbon intensity of their projects.
Features
- Biochar‑derived cement additive that sequesters more CO₂ than is emitted during its own production, achieving a net carbon‑negative concrete mix
- Direct, drop‑in replacement for Portland cement, compatible with all conventional batching and mixing equipment
- Enhances compressive strength and durability, delivering performance equal to or better than standard concrete
- Improves workability and reduces water demand, facilitating easier placement and finishing
- Enables participation in carbon‑credit programs, creating additional revenue streams for projects using the material
