Construction Materials (Mineralization)
Deliver clean CO₂ for curing and mineralisation. Strengthen materials while lowering the footprint of cement-based products.
How It Works
Step-by-step
Our system turns CO₂ into a stable, on-site utility for curing and mineralisation. From initial gas capture and purification through to buffering, storage, and optional liquefaction, each step is designed to match your curing cycle profile and yard layout. The result: consistent quality, predictable schedules, and fewer delivery-related risks.
Source & capture
CO₂ is extracted from flue gas (cement kilns, industrial plants) or upgraded biogas streams. The capture module analyses gas composition, removes major non-CO₂ impurities (moisture, H₂S, etc.) and ensures it meets purity targets safe for curing and mineralisation.
Purification & conditioning
After capture, gas is purified via filtration, drying, and sometimes polishing to remove trace impurities. This ensures that the CO₂ will not impair material properties or cause staining or other defects in concrete or blocks.
Buffer storage & dosing
CO₂ is stored in buffer tanks sized to your plant’s needs. Dosing systems distribute the gas in curing chambers or mixes as needed, with controls to ensure the correct ppm, consistent exposure, and minimal losses. Storage may include liquefaction where needed to manage footprint or transport between sites.
Performance & monitoring
Continuous monitoring of CO₂ concentration, moisture, temperature, and dosing stability ensures consistent material quality. Feedback loops help adjust flow, shutdowns, or calibrations so the CO₂ supply stays reliable and product performance (strength, curing rate) remains uniform.
Yield impact
~20% higher early strength (24 h) with on-site CO₂
On-site CO₂ stabilises chamber conditions so targets are reached faster and turnarounds stay predictable. Plants typically see earlier demoulding, tighter strength uniformity and fewer unplanned holds, without over-holding inventory. Benchmark: ~+20% early strength at 24 hours (typical, mix-dependent; validate on your plant recipes).

Benefits
Benefits of construction materials
Using captured CO₂ in construction materials isn’t only about supply security, it fundamentally reshapes how your curing lines and mineralisation processes operate. By turning CO₂ into a reliable, on-site utility, you gain stability, efficiency, and a measurable sustainability advantage. Each benefit extends beyond cost savings to touch product quality, compliance, and long-term competitiveness in the low-carbon construction market.
Permanent carbon locking in materials
When CO₂ is injected during mineralisation, it doesn’t just disappear, it chemically binds with calcium in cementitious materials, forming stable carbonates. This permanently locks carbon into concrete, blocks, or panels for decades, preventing it from returning to the atmosphere. In effect, every cured unit becomes a form of long-term carbon storage.
This chemical binding also improves material properties, including reduced porosity, higher resistance to freeze–thaw cycles, and better overall durability. Over the lifecycle of a building, that translates into stronger performance and less maintenance, while also giving you a measurable and reportable sustainability outcome for ESG frameworks and low-carbon certifications.
Improved curing speed & material strength
CO₂-assisted curing accelerates cement hydration, enabling products to achieve strength faster. This means molds and chambers can turn over more quickly, reducing bottlenecks in production lines and allowing earlier demolding without compromising quality. Faster curing cycles reduce labor requirements and inventory buildup, improving throughput across the yard.
Consistent CO₂ supply ensures these gains are repeatable, not subject to fluctuations in deliveries or external suppliers. This predictability leads to tighter scheduling, fewer rejected batches, and uniform strength across all cured products, benefits that directly enhance customer confidence and operational efficiency.
Reduced operational and transport costs
On-site capture removes the dependency on cylinders or bulk CO₂ deliveries, both of which carry recurring costs for logistics, transport, and vendor contracts. By producing and storing your own CO₂, you eliminate rush surcharges, delivery scheduling issues, and the footprint required for external storage.
Safety and handling costs are also reduced. Fewer truck movements mean less congestion in the yard, lower exposure to hazardous transfers, and fewer permits or safety checks tied to external supply chains. Over time, these reductions create a stable and predictable OPEX profile that outperforms traditional supply models.
Predictable CO₂ purity & quality
Captured CO₂ is purified and conditioned to meet the specific standards required for concrete curing and mineralisation. This ensures that harmful impurities, such as excess moisture, sulphur compounds, or dust, are removed before use, preventing quality issues like surface blemishes, inconsistent coloration, or long-term durability concerns.
Integrated sampling points and sensors allow for monitoring at every stage, providing traceability for audits, certifications, and customer assurance. For producers working with green building labels or regulatory frameworks, this level of documented quality helps secure compliance while safeguarding product consistency.
Scalable system for evolving demand
The modular nature of CO₂ capture and liquefaction means you can right-size the system for today’s production and scale up as curing demand grows. Additional capture modules, storage units, or liquefaction stages can be added without major redesigns, keeping capital expenditures aligned with actual business needs.
This flexibility ensures your operation stays future-proof. Whether growth comes from added curing chambers, stricter emissions limits, or demand for sustainable materials, your system evolves in step. You avoid overbuilding capacity too early while still staying ahead of market and regulatory expectations.
Enhanced sustainability & market differentiation
By incorporating captured CO₂ into your curing process, you turn a waste stream into a sustainability asset. This allows you to position your materials as “CO₂-enriched” or “low-carbon” in the marketplace, attributes that increasingly influence procurement choices by architects, developers, and government projects.
Such differentiation not only strengthens your brand but can also qualify your products for subsidies, tax incentives, or preferred supplier lists. In competitive tenders, being able to demonstrate permanent carbon sequestration can be the deciding factor that sets you apart.
More reliable scheduling & smoother logistics
A stable on-site CO₂ supply means production is no longer tied to truck deliveries or vendor schedules. Curing chambers can run consistently without unexpected delays, helping operators keep demolding, packaging, and shipping timelines on track. This translates into smoother yard logistics and fewer last-minute workarounds.
With buffer storage and optional liquefaction, even peak periods or multi-building operations can be handled without disruption. By reducing reliance on external supply chains, your plant gains autonomy and resilience, ensuring projects run on time and reducing costly downtime.

All frequently asked questionsDeliveries often introduce variability: delays, fluctuating purity, or limited storage capacity can cause curing cycles to run off-spec. On-site capture provides a steady, controlled CO₂ stream that matches your chamber profile exactly. This stability reduces waste, improves early strength development, and helps maintain consistent production schedules. It also eliminates the need to buffer operations around vendor truck arrivals.
Yes. The system purifies CO₂ by removing moisture, sulphur, particulates, and other impurities that could otherwise affect curing performance or material durability. Quality is monitored with sensors and sampling points to ensure compliance with curing specifications and certifications. This means every batch of blocks, panels, or precast components receives the same high-quality CO₂ exposure, with full traceability for audits.
Most operators see a return on investment within 2–5 years. Savings come from avoiding cylinder purchases, lowering delivery logistics, reducing downtime, and reusing recovered energy when combined with flue-gas integration. The modular design also means you don’t overspend up front; capacity can be added over time as curing demand grows. After payback, the system continues delivering long-term operational savings and sustainability benefits.
