COâ‚‚-Reactive Circular Aggregates
Rockpore AS develops COâ‚‚-reactive circular lightweight aggregates (CLWAC) designed to permanently store carbon through controlled mineral carbonation. By engineering calcium-silicate phases to react with COâ‚‚, the aggregates function as an active carbon sink, embedding captured carbon directly into structural materials for infrastructure and marine applications.
The technology is currently being validated at TRL 7 through pilot-scale production and demonstration activities within European research and innovation programmes. This validation confirms mechanical performance, durability, carbonation behaviour, and scalability under relevant operating conditions, ensuring compatibility with demanding infrastructure and marine environments.
Carbon storage is an intrinsic material property rather than an add-on process. COâ‚‚ is mineralised into stable carbonates at the aggregate surface and remains locked into the structure throughout its service life. At end of life, crushed concrete can be reused as feedstock for new aggregates, enabling additional carbonation on freshly exposed surfaces and supporting cumulative COâ‚‚ storage across material generations.
Rockpore’s carbonation process, together with CLWAC products and their applications, is patent pending in Norway and Europe, providing a scalable, high-performance pathway for industrial decarbonisation in concrete, infrastructure, and marine construction systems.
Artificial Turf:
Transforming Football Pitches into Carbon Sinks
Arctic Greenstone is a COâ‚‚-reactive, microplastic-free infill for artificial turf systems, developed to replace rubber crumb in advance of forthcoming EU restrictions.
Engineered from circular mineral feedstocks, it permanently stores COâ‚‚ through mineral carbonation, eliminates microplastic pollution, reduces lifecycle costs, and enables compliant, circular sports infrastructure with long service life.
Structural Concrete:Carbon-Capturing Concrete for Marine Infrastructure
Arctic Stone enables COâ‚‚-storing concrete for demanding marine applications such as breakwaters, quay structures, and offshore foundations.
Its engineered, COâ‚‚-reactive surface promotes mineral carbonation, enhancing durability, reducing permeability, and supporting long-lived, low-carbon marine infrastructure aligned with climate and resilience objectives.
COâ‚‚ Storage and Circular Reuse
Rockpore AS integrates carbon capture and storage directly into the lifecycle of its COâ‚‚-reactive circular lightweight aggregates (CLWAC). COâ‚‚ is permanently locked through natural mineral carbonation and stabilised as solid carbonates, transforming end-use applications into durable, passive carbon sinks.
Stored COâ‚‚ is retained throughout use, reuse, and reprocessing, with carbonation optimised to maximise long-term climate impact across material generations. This approach reinforces circularity, supports carbon-neutral construction pathways, and aligns with regulatory and ESG requirements—offering a scalable, compliant alternative to conventional aggregate systems.
Patent pending.
