The technology

From captured CO₂ to mineralized concrete.

We inject captured CO₂ into concrete mixers where it permanently reacts with cement to form calcium carbonate — locking carbon into the every buildings, pavers and infrastructure that shape modern cities.

01

CO₂ Capture

Industrial sources provide verified captured carbon ready for use.

02

Injection

Precision-metered CO₂ is injected directly into the concrete mixer.

03

Mineralization

CO₂ reacts with cement chemistry forming stable calcium carbonate.

04

Permanent Storage

Carbon locked into the concrete matrix for geological timescales.

Permanent removal

Over 1,000 years of storage durability — geological permanence.

Measurable impact

Per-batch MRV with auditable, registry-grade accounting.

Cement reduction

Up to 20% less Portland cement per cubic meter delivered.

Performance gains

Improved early strength and densified microstructure.

Verified carbon

Aligned with leading registries and durable removal standards.

Scalable deployment

Drop-in technology for existing ready-mix infrastructure.

Cement reduction

Reduce cement usage by up to 20% — In Concrete.

Mineralized CO₂ improves early strength so producers can re-formulate mix designs with less Portland cement — cutting embodied carbon, cost and emissions in a single move.

  • Lower clinker demand without losing strength
  • Validated mix designs across precast and ready-mix
  • Auditable savings per batch, per project
  • Stacks with SCMs and other low-carbon strategies
