Hydroponics:
Carbon Capture in Agricultural Systems
With rising food demand and limited agricultural land, hydroponic farming offers an efficient solution. To support this growth, the industry requires sustainable substrates that enhance plant performance while reducing environmental impact.
​
Rockpore’s CLWAC serves as a high-performance growing substrate that also captures and stores COâ‚‚. Unlike expanded clay, which is energy-intensive, CLWAC provides a climate-positive alternative, actively reducing atmospheric carbon levels throughout its lifecycle.
​
Beyond carbon storage, CLWAC’s enhanced aeration and water retention optimize plant growth, reducing water and nutrient waste. Made primarily from silica-rich sand, including desert sand, CLWAC enables local production, lowering transportation emissions and offering a scalable solution for hydroponic farming, especially in arid regions.
​
As hydroponics expands, Rockpore’s CLWAC provides a circular, locally sourced alternative that boosts crop yields while supporting climate goals.
Artificial Turf:
Transforming Football Pitches into Carbon Sinks
Sports infrastructure is shifting toward sustainability, and Rockpore’s CLWAC leads the way. With the EU phasing out rubber crumb infill, the demand for high-performance, eco-friendly alternatives is growing. CLWAC turns football pitches into carbon sinks, actively removing COâ‚‚ from the atmosphere while eliminating microplastic pollution.
​
A football pitch using CLWAC captures and stores COâ‚‚ over its lifespan, supporting carbon neutrality goals. Unlike conventional infill, it reduces reliance on virgin materials, minimizes waste, and aligns with circular economy principles.
​
CLWAC also lowers operating costs through durability and reusability, eliminating disposal fees and reducing end-of-life costs. This fully circular approach helps municipalities and sports organizations future-proof investments while meeting EU sustainability regulations.
​
By replacing single-use materials with carbon-storing, recyclable infill, CLWAC redefines sustainable sports infrastructure, delivering performance, cost savings, and long-term environmental benefits.
Structural Concrete:Carbon-Capturing Concrete for Marine Infrastructure
Concrete is a major COâ‚‚ emitter, yet essential for marine infrastructure. Rockpore’s CLWAC offers a new generation low-carbon alternative, integrating carbonation technology into concrete for offshore platforms, breakwaters, and coastal defense systems.
​
As concrete interacts with the environment, CLWAC aggregates mineralize COâ‚‚, converting it into stable carbonate phases.
The reactive surface enhances carbonation, reducing the net carbon footprint while improving durability, lowering permeability, and increasing chemical resistance.
​
By embedding COâ‚‚-reactive aggregates, CLWAC enables long-term carbon storage, supporting sustainable marine infrastructure.
As emission regulations tighten, carbon-storing concrete will be essential in meeting Europe’s climate goals.
COâ‚‚ Storage and Circular Reuse
Rockpore has developed a method to integrate carbon capture and storage (CCS) into CLWAC’s lifecycle, ensuring that COâ‚‚ mineralized during its use phase remains stabilized before reuse or reprocessing*. This process transforms end applications into passive carbon storage reservoirs, reinforcing the role of CLWAC in carbon mitigation and long-term sequestration strategies.
​
By leveraging natural mineralization processes, CLWAC enhances COâ‚‚ stability by converting it into solid carbonate phases, ensuring its durability within the long carbon cycle. Before reprocessing, measures are taken to retain and optimize the stored COâ‚‚, maximizing its climate impact and contribution to net carbon reduction.
​
This approach promotes sustainable material recovery and reuse, aligning with circular economy principles and supporting climate-positive construction and industrial applications. By combining resource efficiency with regulatory compliance, Rockpore’s solutions provide industries and investors with a scalable, high-performance alternative to traditional materials, supporting carbon-neutral and ESG-aligned initiatives across key sectors.
