A New Era of Building

Ferrock is a revolutionary building material that actively removes carbon from exhaust streams. Unlike traditional concrete, which is a major source of global CO₂ emissions, our panels transform from a carbon source into a climate-positive solution. This isn't just a claim, it's a fundamental part of our technology.

How Ferrock Captures Carbon

Ferrock is made from a special blend of iron-rich industrial waste and silica. When combined with water and carbon dioxide gas, a chemical reaction occurs, forming iron carbonate (FeCO₃). This stable mineral permanently locks CO₂ inside the material.

Fe(0) + CO₂ + H₂O → FeCO₃ + H₂

The Outcome

Sequesters Carbon: Permanently captures CO₂ from the air.
Produces Hydrogen: Releases hydrogen gas, a clean fuel by-product.
Emits Nothing: The process is entirely emission-free.

Making a Carbon-Negative Impact

Ferrock is officially carbon-negative. Lab tests show it absorbs 8–11% of its weight in CO₂ during curing. This means every panel actively helps reduce atmospheric carbon.

One ton of Ferrock panels removes up to 110 kg of CO₂.
This is a stark contrast to Portland cement, which emits about 930 kg of CO₂ per ton.

A Dual-Benefit Production System

The same process that captures carbon also produces hydrogen gas, a clean-burning fuel. In a closed-loop system, this hydrogen could be harvested to create a dual-benefit system, providing both a valuable building material and a renewable energy source.

Our Waste-to-Walls Solution

Our process transforms what others discard into high-performance infrastructure. Ferrock’s unique chemistry turns waste materials into a climate-positive solution, proving that you can build for a better planet. As our founder, Dr. David A. Stone, puts it, "This is not carbon-neutral. This is carbon negative."

A Zero-Compromise Approach

Ferrock contains no Portland cement, meaning our production process avoids limestone mining, fossil-fuel-based kilns, and harmful emissions.

We Use Recycled Materials

Steel Dust: The primary iron source.
Fly Ash or Crushed Glass: The silica source.
Wastewater of Sea Water: Used as the mixing agent.
