What Paebbl does

Paebbl AB is a Swedish-registered private climate technology company founded in 2021, headquartered in Rotterdam, the Netherlands, with additional offices in Stockholm, Helsinki, and London. The company has developed a proprietary accelerated mineralisation process—described as 'geomimicry'—that converts captured CO2 and abundant magnesium-silicate minerals into stable magnesium carbonate (e.g., magnesite) and silica under controlled high-pressure and high-temperature conditions. Paebbl's core product, Paebbl Rebond 200, is a carbon-storing Supplementary Cementitious Material (SCM) that can store up to 220 kg of CO2 per tonne of product, replace up to 30% of cement in concrete mixes, and reduce embodied carbon by up to 42% without requiring changes to standard ready-mix or precast workflows.

Paebbl's go-to-market is enterprise-led, with direct sales to major construction companies, general contractors, and building materials producers including Heijmans, GOLDBECK, Holcim, Hakkers, and Byldis. Distribution is channelled through these partners' existing supply chains—Holcim integrates Rebond into its ready-mix at the Offenburg plant, Byldis produces precast façade panels, and specialist applicators like Australe Concrete and Design & Beton deliver architectural microcement finishes. Revenue streams include one-time SCM product sales, turnkey on-site mineralisation solutions for industrial emitters, and usage-based CO2 storage-as-a-service for DAC/DOCC operators. Pricing is not publicly disclosed and is structured on quote/bulk purchase bases.

The company has scaled production capacity 2,500x in under two years, from bench scale to a continuous demo plant in Rotterdam operating since March 2025 at 0.4-0.9 kt CO2/year. A First-Of-A-Kind commercial plant is targeted for H1 2028 at 10-20 kt CO2/year. Paebbl has raised approximately $43 million cumulatively (€8M seed in October 2022, $25M Series A in October 2024 led by Capnamic, plus €4M EIC grant and $2.2M Dutch DEI+ grant), and was named to AWS's Pioneers Project in 2025 and 2026 for its advanced AI and cloud adoption. The co-founders Marta Sjögren and Andreas Saari continue as co-CEOs, supported by a leadership team that includes a dedicated FOAK CEO, VP of Finance, VP of Engineering, VP of Products, and a fractional COO, along with a team of approximately 60 employees across 25 nationalities.

Revenue model

1. Carbon-Storing SCM Product Sales: Paebbl sells its Paebbl Rebond 200 supplementary cementitious material directly to construction companies, ready-mix producers, precast manufacturers, and contractors. The product replaces a portion of traditional cement in concrete mixes and generates revenue per tonne of product sold. Revenue is derived from the material's dual value: embodied carbon reduction (captured in EPDs) and verified carbon removal credits (CDR) from permanently stored CO₂. Customers include Heijmans, Holcim, GOLDBECK, Hakkers, Byldis, and others.
2. Turnkey Decarbonisation Solutions: Paebbl offers end-to-end carbon management solutions for selected industries, including carbon capture and sequestration as an integrated on-site solution — removing the need for pipeline infrastructure or extensive liquefied CO₂ logistics. This is described as 'turnkey decarbonisation' for industrial operations looking to integrate CO₂ mineralisation on-site.
3. CO₂ Storage as a Service: For Direct Air Capture, Direct Ocean Capture, or industrial operations with existing carbon capture solutions, Paebbl offers fully verified permanent CO₂ sequestration as a service. Revenue is generated per tonne of CO₂ permanently sequestered in mineral form, with full MRV documentation and alignment with EU carbon removal frameworks.

Core offering

Paebbl converts captured CO2 into a high-performance Supplementary Cementitious Material (SCM) called Paebbl Rebond 200 using proprietary accelerated mineralisation technology, a controlled high-pressure, high-temperature aqueous mineral carbonation process that permanently locks CO2 into stable magnesium carbonate mineral powder. The SCM is sold to construction companies, ready-mix concrete producers, precast manufacturers, and infrastructure developers, replacing up to 30% of cement in concrete mixes while achieving up to 42% embodied CO2 reduction and storing up to 220 kg CO2 per tonne of product. Paebbl also offers turnkey on-site CO2 mineralisation and storage-as-a-service solutions for industrial emitters and DAC operators.

Product overview

Paebbl offers a portfolio of carbon-storing construction materials centred on its proprietary Paebbl Rebond 200 product. This high-performance Supplementary Cementitious Material (SCM) uses accelerated mineralisation technology to convert captured CO₂ into stable mineral powder, which is then used as a partial cement replacement in concrete. The product integrates with standard ready-mix and precast concrete workflows and can be specified using the company's CO₂ Calculator tool. Paebbl's materials portfolio covers structural applications (bridges, floor slabs, harbour infrastructure, façade panels) and architectural applications (microcement flooring), demonstrating versatility across the construction industry.

Direct peers

• Carbon Upcycling Technologies: Canada-based company that uses CO2 to produce supplementary cementitious materials from industrial by-products (fly ash, steel slag). Direct competitor targeting the same drop-in SCM value proposition for ready-mix and precast concrete applications.
• CarbonCure Technologies: Canadian company that injects captured CO2 into ready-mix concrete during batching, where it mineralises and is permanently stored. Direct competitor in the CO2-storing concrete category, with overlapping customers (ready-mix producers and contractors) and a similar dual climate-impact narrative, but using a different mineralisation mechanism (concrete pore solution vs. aqueous Mg-silicate carbonation).
• Solidia Technologies: US-based developer of CO2-cured concrete and reduced-CO2 cementitious binders using mineral carbonation chemistry closely related to Paebbl's. Competes for the same low-carbon SCM and concrete market, with parallel efforts in EPD documentation, ready-mix integration, and CDR credit monetisation.
• Solidia Technologies: (See primary Solidia entry above; listed again to highlight its parallel commercial-scale pilots in CO2-cured precast concrete, directly comparable to Paebbl's Byldis and GOLDBECK projects.)
• Ecocem: Ireland-based low-carbon cement and SCM producer (ground granulated blast-furnace slag and ACT technology) supplying European ready-mix and precast markets. Closely comparable in product type (high-replacement SCM), customer base (European construction and building materials majors), and scale-up trajectory.

Emerging players

• Brimstone: California-based company developing a carbon-negative Portland cement from calcium silicate produced from industrial waste streams. A direct aspirational peer in the carbon-negative cement category, targeting the same construction-industry decarbonisation demand.
• Sublime Systems: US-based startup producing low-carbon cement via an electrochemical process that avoids traditional kiln emissions. Competes for the same decarbonisation budget from cement buyers and construction companies, even though the underlying chemistry (electrolytic vs. mineralisation) differs.
• CarbonOrO: Canadian CO2 capture and utilisation company with deployment in cement and other heavy industries. Emerging player in the same mineral/utilisation value chain, providing CO2 capture solutions that could either feed Paebbl's reactors or compete for the same CDR credit pipeline.

Broad incumbents

• Heidelberg Materials: One of the world's largest cement and building materials groups, with an active portfolio of low-carbon cements, CCUS projects, and SCM offerings. A broad incumbent competing for the same low-carbon construction budget and a potential partner/acquirer in the mineral carbonation space.
• CEMEX: Global building materials major with a significant Vertua low-carbon concrete portfolio and CCUS pilots (e.g., Carbon Neutral Alliance). Competes for the same decarbonisation-driven procurement budgets and is a logical partner or competitive threat in carbon-storing concrete.
