Quel est le problème résolu ?
Traditional mineral production relies on extractive quarrying, energy-intensive processing, and volatile supply chains, leading to high costs, regulatory risks (health, environmental compliance), import dependency, and a significant environmental footprint (CO2 emissions, pollution, habitat loss). There is a lack of local, high-performance, and secure alternatives that can stabilize costs and strengthen supply resilience.
Comment est-il résolu ?
Bloomineral utilizes a biomineralization process that combines carbon removal with industrial alkaline waste and atmospheric CO2. Alkaline residues are mixed with seawater to capture CO2, which is then biologically transformed by calcifying microalgae into solid CaCO3 (aragonite crystals). This process is carbon-negative, produces high-purity CaCO3, and can replace traditional minerals in various applications like cement, PCC, TiO2, talc, and mica. The technology is modular and can be deployed on-site.
Materials characteristics include carbon-negative production (0.44 tCO2 stored per ton of mineral product), high purity (>99% aragonite), controlled morphology, drop-in behavior for seamless integration, cost-competitiveness (up to 5x lower than TiO2, ~1.5x lower than PCC), waste upcycling, reduced industrial emissions, and enhanced climate adaptation properties (like high solar reflectance for building cooling).
Industrially, our production units are designed to be modular and co-located with industrial sites, particularly where alkaline residues are generated. This deployment model creates local circular supply chains, reduces transport requirements and transforms underutilized waste streams into valuable products. By combining carbon removal and material production in a single process, Bloomineral creates a dual-value model capable of generating both environmental and economic benefits at industrial scale.
Qui sont les clients potentiels ?
Secured first LOI with Enercool for cool-roof applications. Obtained multiple letters of support from major players (EQIOM, Holcim, Vinci, Unikalo). Under NDA with BASF, Omya, Imerys, Arkema/Bostik. Signed 3 MTAs with paying customers in paints, construction, and cosmetics for sample validation. Planning pilot deployment in Sept 2026.
En quoi cette solution est-elle différente ?
Bloomineral is transforming mineral production by combining atmospheric CO₂ capture and mineralization into a single biological process. Unlike conventional production methods that rely on quarrying, high-temperature calcination, or concentrated CO₂ streams, our system operates under ambient, low-energy conditions and simply turns CO₂, seawater, and industrial residues into high-performance calcium carbonates.
This enables simultaneous carbon removal and material production in single process without energy-intensive steps. The resulting minerals are ultra-pure, finely controlled and drop-in compatible with industrial applications, allowing substitution of carbon-intensive materials while improving performance.
Our breakthrough approach also stands out through its ability to use diverse industrial waste streams and its modular, co-located deployment model, enabling circular production and local integration into existing supply chains. This combination of low-energy operation, material performance and industrial scalability represents a foundational change compared to existing solutions.
