Turning Agricultural Waste and Ocean Brine Into the Ultimate Carbon Sink

Traditional Carbon Capture and Storage (CCS) has a massive problem: it’s an expensive storage bill. Companies spend millions of dollars pumping high-pressure carbon dioxide gas underground, crossing their fingers that it never leaks.

What if carbon capture wasn’t a structural liability, but a highly profitable manufacturing engine?

Introducing Biogenic Sodium Silicate CCU—a breakthrough closed-loop system that transforms industrial CO2 emissions into high-value, market-ready minerals using nothing but agricultural waste and seawater. We don't hide carbon; we monetize it.

The Innovation: The Biogenic Cycle

Unlike traditional, energy-heavy synthetic silicates, our method is completely circular, utilizing two ultra-abundant, low-cost inputs:

• Rice Husk Ash (RHA): An agricultural waste product packed with up to 95% amorphous silica (SiO2).

• Seawater & Brine: Electrolyzed using renewable energy to produce sodium hydroxide (NaOH), even better it is also byproduct of CDI+BMED desalination.

By dissolving RHA in seawater-derived base, we extract a low-carbon, biogenic sodium silicate liquid. When this liquid comes into contact with industrial flue gas (CO2), a rapid, permanent mineralization reaction triggers instantly.

The Chemistry: Instant Mineralization

Our system bypasses the high-heat regeneration loops required by traditional amine scrubbers. We rely on a natural, exothermic chemical transformation:

Na2SiO3 (aq) + CO22(g) + H2O—> Na2CO3(aq) + SiO2(as high-purity gel)

The carbon is permanently, chemically locked. It cannot degrade, leak, or escape back into the atmosphere—even under intense heat or pressure.

The Value Proposition: One Waste In, Two Commodities Out

Every ton of CO2 scrubbed yields two distinct, high-margin, commercially highly sought-after material results:

1. Green Silica Gel (SiO2)

• Market Applications: High-performance tire additives (green tires), advanced desiccants, catalyst carriers, and battery anode additives.

• The Disruption: Replaces traditional, high-carbon synthetic silica with a fully sustainable, biogenic alternative.

2. Green Sodium Carbonate (Na2CO3)

• Market Applications: Essential raw material for glass manufacturing, soaps, detergents, and chemical syntheses.

• The Disruption: Allows manufacturers to radically lower their Scope 3 supply chain emissions by sourcing mineralized carbon.
