What Karbonetiq does

Karbonetiq is a private carbon removal company that deploys accelerated mineral carbonation at industrial sites to permanently store CO2 as stable solid carbonates. The company partners with industrial operators — including steel mills and cement plants that generate mineral-rich byproducts such as slags and ash — to co-develop on-site mineralization projects using materials already managed at those facilities. Its core technology accelerates natural mineralization through material preparation (crushing and sizing to increase surface area) and controlled placement for air and moisture exposure, achieving CO2 uptake up to 250 times faster than untreated material and converting a multi-decade natural process into one measured in weeks. The resulting carbonate storage is engineered for permanence over 1,000+ years with very low reversal risk, and the process requires no added chemicals, no combustion, and no new infrastructure.

The company monetizes its service by issuing verified carbon removal credits through registry partners Puro.earth and Isometric, which are sold to corporate carbon buyers including Google, Shopify, Stripe, Klarna, Frontier, Milkywire, and Artemeter. Karbonetiq operates a direct enterprise field-sales go-to-market, with projects designed for replication across regions where suitable mineral-rich materials exist. Its end-to-end Measurement, Reporting, and Verification (MRV) system combines on-site sensors, periodic field sampling, lab analysis, and independent registry review to produce a full audit trail from material batch to credit issuance. The company is headquartered as a private for-profit entity with 11-50 employees and is led by CEO and co-founder Michael Wyrsta alongside co-founder Mark Tilley.

Revenue model

1. Carbon Removal Credit Sales: Karbonetiq earns revenue by delivering verified carbon removal credits to corporate buyers. Credits are issued through industry-leading registry partners (e.g., Puro.earth, Isometric) following end-to-end MRV. The company co-develops and operates mineralization projects at industrial sites, generating credits that are sold to buyers such as Frontier, Google, Shopify, Stripe, Klarna, Milkywire, and Artemeter. Revenue is outcome-based, tied to verified tonnes of CO₂ removed and stored durably.

Core offering

Karbonetiq delivers durable carbon removal by accelerating the natural reaction of CO2 with mineral-rich industrial byproducts (slags, ash) to form stable solid mineral carbonates at industrial sites. The company co-develops on-site mineralization projects with industrial operators, prepares material through crushing and sizing to increase surface area, places it for air and moisture exposure, and runs end-to-end MRV with on-site sensors, lab analysis and independent registry review to issue verified carbon removal credits to corporate buyers.

Product overview

Karbonetiq offers a single unified carbon removal service based on accelerated natural mineralization. The core Carbon Removal via Mineralization product processes mineral-rich industrial byproducts (slags, ash, and similar materials) into durable solid carbonate storage for 1,000+ years, operating 250x faster than unassisted natural processes. This core offering is supported by the MRV (Measurement, Reporting, and Verification) module, which provides end-to-end documentation from on-site sensors and lab analysis through to credit issuance by registry partners.

Functional benefit

Products and services

• Carbon Removal via Mineralization End-to-end carbon removal service that mineralizes CO2 into solid carbonate form using mineral-rich industrial byproducts (slags, ash) already managed on-site. The service covers material suitability assessment, surface-area preparation (crushing to 0-25mm), placement for air and moisture exposure, on-site sensors and sampling, lab analysis, and credit issuance through registry partners. Buyers are corporate sustainability programs seeking durable, independently verified removal credits with 1,000+ year storage and very low reversal risk.

Quantifiable outcome

• Up to 250x faster CO₂ uptake compared to untreated material, reducing mineralization from decades to weeks
• +3 more outcomes
