As climate change continues to pose a critical global challenge, TerraFixing is leading the charge with their affordable and scalable Direct Air Carbon Capture (DAC) technology. Unlike conventional methods, their groundbreaking approach can efficiently capture CO2 directly from the atmosphere—even in colder climates—making their solution unique in the industry. By reducing current CO2 emissions and addressing historical carbon footprints, TerraFixing is paving the way toward achieving global net-zero targets.

TerraFixing’s Zeolite-based technology

At the core of TerraFixing’s innovation lies their use of zeolite monoliths—microporous, aluminosilicate minerals renowned for their exceptional CO2 adsorption capabilities. These cost-effective and durable materials have a proven track record in industrial applications spanning over two decades.

The monoliths are crafted with a composite of zeolite crystals and binders, maximizing the surface area for CO2 capture while ensuring structural strength. This dual functionality is essential for the long-term success of TerraFixing’s DAC systems.

Leveraging the Mecmesin OmniTest 25 for quality assurance

To maintain the structural integrity and operational efficiency of their zeolite monoliths, TerraFixing relies on the Mecmesin OmniTest 25 universal testing machine. This versatile instrument plays a pivotal role in testing the mechanical properties critical to the DAC process.

Testing objectives: The OmniTest 25 evaluates two key parameters:

• Cold Crushing Strength (CCS): Ensuring monoliths can endure mechanical stress during operation.
• Modulus of Rupture (MOR): Assessing the structural robustness under applied loads.

All testing is conducted in compliance with ASTM C133-97 standards, ensuring the materials meet stringent quality and durability benchmarks.

Why the OmniTest 25?

Several features make the Mecmesin OmniTest 25 an indispensable part of TerraFixing’s R&D labs:

1. Capacity: Its 25 kN capacity accommodates the rigorous demands of TerraFixing’s large-scale monoliths.
2. Precision and reliability: Accurate measurements are crucial for evaluating the mechanical properties of their adsorbents.
3. VectorPro software integration: The advanced software simplifies test execution and data analysis, providing powerful reporting capabilities and customizable protocols. This streamlines workflows for both novice and expert users.
4. In-House testing capabilities: Transitioning from outsourced testing to in-house processes has enabled TerraFixing to achieve faster feedback, greater control, and seamless integration into their material development cycles.

Implementation and benefits

Testing workflow:

• Monolith preparation: Zeolite monoliths are meticulously prepared for testing.
• Mechanical testing: Using the OmniTest 25, the crushing strength and durability of the monoliths are evaluated.
• Data collection and analysis: VectorPro software captures critical performance data, facilitating real-time monitoring and detailed reporting. This enables TerraFixing to continually refine their materials and manufacturing processes.

Quality assurance: Approximately 20 monoliths are produced and tested monthly, ensuring each meets rigorous quality standards before deployment.
