What is the primary mission of Sequestra?
Sequestra is a climate technology company that develops and commercializes solutions for the permanent binding of CO2 in industrial residual materials to create sustainable secondary raw materials for the construction sector.
How does Sequestra's carbonation technology work?
Sequestra utilizes a data-driven process that accelerates natural mineralization, converting CO2 into stable carbonates within hours rather than millennia, effectively locking emissions into a rock-like form.
Which materials can be processed using Sequestra's systems?
Sequestra is designed to handle a variety of industrial residues, including steel slag, incineration ash, and demolition debris, turning these waste streams into usable building materials.
What is the CO2 storage capacity of Sequestra's solution?
Depending on the specific industrial material used, the technology can permanently store up to 300 kg of CO2 per ton of residue.
How does Sequestra ensure the efficiency of the mineralization process?
The company uses a proprietary, fully automated analysis technology and machine learning to identify the optimal process parameters for different waste materials, ensuring cost-optimized and reliable carbonation.
Is the technology provided by Sequestra recognized by environmental regulations?
Yes, the accelerated carbonation process is a legally recognized form of permanent industrial CO2 utilization and is an EU ETS-approved form of Carbon Capture and Utilization.
