What Carbon Blue does
CarbonBlue (legal entity Carbon Blue Ltd.) is an Israeli climate-tech startup founded in 2022 by Dr. Dan Deviri and Iddo Tsur, headquartered in Haifa, Israel. The company has developed EcoLime, a patented, fully electrified electrochemistry-based lime production technology that operates at ambient temperatures and extracts high-quality hydrated lime from low-quality waste feedstocks — including steel slag, construction and demolition waste, and quarry fines — without combustion or fossil fuels. This represents a fundamental architectural departure from the 3,000-year-old kiln-based lime manufacturing process that burns limestone at approximately 1,000°C and accounts for roughly 8% of global CO2 emissions.
The company's commercial proposition targets enterprise industrial customers seeking to decarbonize lime consumption and unlock circular mineral production. Primary customer segments include steel producers (circular slag-to-lime reuse), precipitated calcium carbonate (PCC) manufacturers, Kraft-process pulp and paper mills (lime reclamation stage), and carbon dioxide removal (CDR) technology companies requiring sustainable alkalinity inputs for direct air capture, ocean alkalinity enhancement, enhanced rock weathering, and water treatment carbon sequestration. EcoLime's small form factor enables on-site deployment at customer facilities, shortening supply chains and creating a dedicated site-specific lime and mineral upcycling asset.
CarbonBlue generates revenue through technology licensing, equipment deployment, and ongoing service agreements with industrial customers. Pricing is not publicly disclosed and is structured on a custom enterprise basis tied to deployment scope. The go-to-market is direct enterprise field sales targeting large industrial operations in steel, pulp and paper, construction materials, and the CDR sector, with planned geographic expansion across Europe, MENA, and North and South America.

Carbon Blue product offering
Product offeringCore offering
CarbonBlue develops and deploys EcoLime, a patented, fully electrified electrochemistry-based lime production technology that operates at ambient temperatures and extracts high-quality hydrated lime from low-quality waste feedstocks including steel slag, construction and demolition waste, and quarry fines. The technology is deployed on-site at industrial facilities as a dedicated lime and mineral upcycling unit, eliminating the need for 1000°C kiln combustion and fossil fuels used in traditional lime production.
Product overview
CarbonBlue offers a single unified core product called EcoLime — a proprietary electrified lime production technology. EcoLime uses electrochemistry to break down calcium-bearing industrial waste into high-quality lime and other valuable minerals, operating at ambient temperatures without combustion or fossil fuels. The technology enables on-site deployment at industrial facilities, allowing steel producers, pulp and paper mills, and construction materials companies to extract and circularly reuse lime from their waste streams, replacing traditional kiln-based production methods.

Company assessmentEmerging players
Direct peers
- Sublime Systems: Sublime Systems uses electrochemistry to produce low-carbon cementitious materials at low temperatures, an almost identical architectural approach to CarbonBlue's EcoLime. Both target hard-to-abate industrial materials via ambient-temperature electrochemical processes, making them the closest technology peer in the climate-tech landscape.
- Heirloom Carbon: Heirloom operates a DAC technology that captures CO2 using a lime/calcium oxide cycle — directly mirroring the use case CarbonBlue enables for the CDR industry. Both companies are commercializing lime-based carbon removal pathways and serve overlapping CDR buyers including the Frontier coalition.
- Brimstone: Brimstone produces carbon-negative Portland cement and supplementary cementitious materials using mineral feedstocks and carbonation, addressing the same ~8% of global CO2 emissions from industrial mineral production that CarbonBlue targets. Both pursue process-emission-free mineral chemistry for heavy industry.
- Fortera: Fortera manufactures low-carbon cement from industrial CO2 and mineral feedstocks, competing for the same industrial decarbonization buyers as CarbonBlue. Both companies license process technology to cement and lime-adjacent industries to displace fossil-fuel-based thermal routes.
- CarbonCure Technologies: CarbonCure injects captured CO2 into fresh concrete to mineralize it permanently, targeting concrete producers — a customer segment adjacent to CarbonBlue's PCC, steel, and construction materials customers. Both decarbonize industrial mineral value chains via technology licensing to incumbents.
- Solidia Technologies: Solidia Technologies uses CO2 curing to produce low-carbon concrete and offers related decarbonization processes for cement and lime-adjacent materials. Both companies sell process technology that displaces kiln-based chemistry with lower-temperature, lower-emission routes for industrial materials.
Broad incumbents
- Carmeuse: Carmeuse is one of the world's largest lime producers, supplying the same steel, pulp & paper, and water-treatment end-markets CarbonBlue targets. As the broad incumbent, Carmeuse represents both the primary competitive threat and a likely partner/customer for licensing EcoLime into existing asset bases.
- Graymont: Graymont is a leading North American lime producer serving steel, construction, and environmental applications. As a broad incumbent in lime, Graymont is the type of incumbent customer/channel CarbonBlue's enterprise field-sales motion will engage to deploy EcoLime units on-site.
- Lhoist: Lhoist is a global lime and mineral products leader with deep presence in Europe and industrial end-markets identical to CarbonBlue's targets. As a broad incumbent, Lhoist is both a competitor (kiln-based) and a candidate technology licensee for the EcoLime platform.
