What Arca Climate Technologies, Inc. does

Arca Climate Technologies, Inc. is a Vancouver-based carbon dioxide removal (CDR) company that uses industrial mineralization to permanently store atmospheric CO2 as stable carbonate rock in alkaline industrial waste streams, principally mine tailings and steel slag. The company's core technology stack comprises three pillars: (1) Mineral Activation, a patented microwave-based process that breaks down magnesium-silicate mineral lattices and reportedly increases CO2 reactivity of mine waste by more than 1,000x; (2) Smart Churning, autonomous rovers fitted with custom tillers that agitate tailings surfaces to optimize water content, alkalinity and roughness for sustained carbon uptake; and (3) an MRV (Measurement, Reporting and Verification) system built on eddy covariance flux towers, autonomous rover sensors, and an ISO 14064-2-validated methodology, which was confirmed by DNV in June 2025 and aligns with Isometric's Open System Ex-Situ Mineralisation (OSEM) protocol.

Arca generates revenue primarily by selling verified CDR credits to corporate buyers with science-based net-zero targets (Microsoft, Stripe, Shopify, MaRS Discovery District, Watershed), typically under multi-year offtake contracts; pricing is contract-based and not publicly disclosed but is described as significantly below comparable CDR offerings, with industry premium pricing above US$300/tonne for mineralization credits per cdr.fyi. A second revenue stream is profit-sharing with industrial partners who host Arca deployments at mining and steel sites; share economics depend on financial, logistical and deployment support contributed by the partner. R&D and field-deployment costs have been substantially subsidized by non-dilutive Canadian federal and provincial grants (NRC IRAP, NRCan, NorthX/CICE, MICA, inBC) and accelerator awards.

The go-to-market motion is a direct enterprise field-sales model layered with channel partnerships through Frontier, Watershed and Carbon Direct, plus active engagement in coalitions such as the Carbon Removal Alliance and the First Nations Major Projects Coalition. Arca's flagship deployment is the 18-month Mt Keith Mineral Carbonation Project with BHP in Western Australia (completed 2025), which delivered a 10x mineralization rate over baseline and was the first CDR project at an active mine. Operational footprint now spans three continents (North America, South America via Vale, and Australia), with the Giga Metals Turnagain agreement in BC representing the largest locked feedstock opportunity at up to 220 million tonnes of CO2 over a 30-year mine life.

Revenue model

1. Carbon Dioxide Removal (CDR) credit sales: Primary revenue stream: Arca sells verified CDR credits to corporate buyers with science-based net-zero targets. 1 credit = 1 tonne CO2 permanently removed. Pricing depends on contract size and length; significantly lower than most comparable CDR offerings. Long-duration multi-year offtake agreements (e.g., 10-year Microsoft deal for ~300,000 tonnes).
2. Industry Partner profit sharing: Revenue sharing arrangement with Industry Partners (mining, steel) for deployment of Arca's technology at their sites. Share proportion depends on financial investment, logistical investment, and deployment support contributed by the partner.
3. Government and accelerator grant funding: Non-dilutive funding from government programs (NRC IRAP Clean Tech, NRCan, CICE/NorthX, MICA, inBC) used to advance R&D, demonstration pilots, and field deployment projects. Not a sustainable revenue stream but supports technology development.

Core offering

Arca captures atmospheric CO2 and accelerates its conversion into stable carbonate rock through Industrial Mineralization, using patented Mineral Activation (microwave-based mineral lattice breakdown) and Smart Churning (autonomous rover-based surface processing) technologies deployed at heavy-industry sites with alkaline waste (mine tailings, steel slag). The company produces and sells third-party-verified, permanent carbon dioxide removal (CDR) credits to corporate buyers under multi-year offtake contracts, while partnering with mining and steel producers to deploy the technology on-site.

Product overview

Arca Climate Technologies is a single integrated Industrial Mineralization (IMin) company whose core offering is a portfolio of carbon mineralization technologies and CDR credit products. The portfolio centers on its flagship IMin carbon removal pathway, anchored by two patented core technologies — Smart Churning (autonomous rover-based surface processing) and Mineral Activation (microwave-based engineered reactivity enhancement) — supported by on-site MRV (Measurement, Reporting, and Verification) systems validated against ISO 14064-2. These feed into two flagship deployment projects — the Mt. Keith Mineral Carbonation Project (with BHP, an 18-month active-mine demonstration) and the Carbon Sandbox Project (BC-based large-scale MRV testing) — which together produce the durable carbon dioxide removal credits that Arca sells to corporate buyers under offtake agreements.

Direct peers

• 44.01: Oman-based startup that mineralizes CO2 into peridotite rock, producing CDR credits via ex-situ mineralization of ultramafic rock. Direct comparator to Arca's IMin pathway with similar feedstock logic and credit-based revenue model.
• CarbFix: Icelandic CCS/mineralization pioneer that dissolves CO2 in water and injects it into basalt for permanent carbonate storage. Closest comparable in mineralization-based CDR technology and MRV approach.
• Heirloom Carbon: US DAC startup using limestone-based capture with downstream mineralization to permanently store CO2. Combines DAC with mineralization, comparable to Arca's mineralization-first pathway and corporate CDR credit buyers.
• CarbonCure Technologies: Canadian company that injects CO2 into fresh concrete during mixing to mineralize it permanently within building materials. Closest North American peer in mineralization-based durable CDR using industrial material streams.

Emerging players

• Mineral Carbonation International (MCI): Australia-based mineralization R&D venture developing passive mineral carbonation using mine tailings and steel slag. Closest regional peer to Arca's Australia operations and tailings-based feedstock strategy.
• GreenSand: Denmark-based enhanced olivine weathering company spreading crushed olivine on farmland to capture CO2 via natural weathering. Comparable as a mineralization-based CDR pathway targeting voluntary corporate credits.
• Eion Carbon: US-based enhanced olivine weathering startup selling CDR credits to corporate buyers. Comparable as a venture-stage mineralization CDR company competing in the same voluntary market channels.

Broad incumbents

• CarbonCapture Inc. US-based DAC company commercializing solid sorbent direct air capture systems. Broad incumbent in durable CDR competing for the same Microsoft/Frontier-style corporate offtake buyers.
• Climeworks: Swiss DAC leader operating commercial DAC plants paired with underground storage. Broad incumbent in engineered durable CDR with strong corporate buyer relationships against which Arca's mineralization approach is benchmarked.
