Engineering Circular Materials for Long-Life Infrastructure

At Rockpore, we develop mineral materials that upcycle industrial by-products into high-performance, low-emissions solutions. The Arctic Series reflects our circular design approach, focusing on durability, recyclability, and environmental compatibility across applications in construction, marine infrastructure, and sports surfaces.

CO₂ performance is addressed through material chemistry rather than offsets. Selected products incorporate calcium-silicate systems intended to enable mineral carbonation under service-relevant conditions, with performance subject to ongoing validation as the technologies progress through TRL 5–7.

Rockpore is a partner in the CircWind project (Development of circularly optimised material solutions for wind turbine blades and support structures), contributing to the development and validation of circular material systems for demanding industrial environments.

Vitrified Silicate Material (VSM)

The True Circular Mineral Platform

VSM is an engineered mineral material designed as the backbone of truly circular infrastructure systems.

VSM is produced through controlled vitrification of selected mineral and secondary raw materials to form a mechanically strong, chemically stable material with predictable and tunable properties.

VSM is designed as a multi-functional material platform. Depending on how it is processed and used, the same VSM can act as filtration media or thermal bonding agent in advanced construction materials.

A defining characteristic of VSM is circularity by design. After long service life in infrastructure applications, the material can be recovered and reused as feedstock in new high-performance products—without downcycling and without loss of material value.

VSM enables durable infrastructure today while preserving mineral value for tomorrow.

Arctic Stone

The CO₂-Reactive Circular Aggregate

Arctic Stone is a circular lightweight aggregate under development at TRL 5–7, engineered for use in structural concrete applications and designed to align with the requirements of EN 13055.

The material is developed to achieve a high strength-to-density ratio compared with conventional aggregate systems, with the objective of reducing material use and associated emissions at the concrete level. Performance is being validated through pilot-scale production and application-relevant testing.

Arctic Stone is produced from our VSM, combined with recycled materials from the renewable energy industry, and upcycled mining tailings. Each granule is thermally bonded to achieve low water absorption and is surface-modified with a calcium-silicate layer intended to enable mineral carbonation under service-relevant conditions.

After use, the granules are designed to be recoverable and reprocessed into new aggregates with comparable properties, supporting a continuous material life cycle and circular use of resources.

Arctic Greenstone

The Sustainable Infill for Artificial Turf

Arctic Greenstone is a mineral infill under development at TRL 5–7, engineered to replace rubber-based granules in artificial turf systems while meeting functional and environmental requirements.

Produced from our novel VSM and upcycled mining tailings, Arctic Greenstone avoids polymeric content and associated microplastic emissions, while maintaining the technical characteristics required for playability, drainage, and field stability. Performance is being validated through pilot-scale testing and use-case–relevant evaluations.

Designed for outdoor exposure and mechanical wear, the material is intended to deliver consistent behaviour across varying weather conditions. Its mineral composition supports environmental compatibility and a closed-loop approach to turf system materials as development progresses toward industrial readiness.
