Carbon Removal (CDR)
Nature‑based, carbon‑negative technology supporting climate goals and circular nutrient management.
Rookwood develops solutions that not only address nutrient pollution but also deliver meaningful, measurable contributions to climate action. Through our nuRe® approach and patented PRM® technology, we offer a unique pathway that combines water quality improvement with verified carbon dioxide removal (CDR).
A Dual‑Impact Approach to Climate and Water
Our systems tackle two major environmental challenges at once:
- excess nutrients in water, which drive ecological damage
- atmospheric carbon, which contributes to climate change
By embedding carbon‑negative materials into nutrient recovery systems, Rookwood enables organisations to improve water quality and achieve climate‑positive outcomes through CDR credit generation.
PRM® — A Carbon‑Negative Material with Long‑Term Impact
PRM® (Phosphate Recovery Material) is central to our carbon‑removal capability. It is engineered from modified biochar — a natural, stable carbon form created from underutilised bioresources.
Why PRM® is Carbon‑Negative
- The biomass used in PRM® production sequesters CO₂ as it grows.
- Our manufacturing process locks that carbon into a durable, stable material.
- Once deployed, PRM® continues to store carbon for the long term, even after nutrient recovery.
This results in more carbon being removed from the atmosphere than is emitted during production, making PRM® a genuinely carbon‑negative product.
PRM® —
CDR Credit Generation
Because PRM® permanently stores carbon in a mineralised or biochar‑stabilised form, it can contribute to verified carbon removal credits.
PRM® enables CDR by:
- Permanently binding atmospheric carbon within a stable matrix
- Delivering quantifiable carbon storage per tonne of material
- Supporting third‑party verification pathways for carbon credit issuance
- Providing climate benefits alongside nutrient recovery
Organisations deploying PRM® may be able to generate measurable CDR credits, contributing directly to net‑zero and climate‑mitigation strategies.
CDR + Nutrient Recovery: A Rare Combination
Rookwood’s system offers both:
1. Environmental protection
- Removes phosphate from water
- Reduces eutrophication risk
- Restores ecosystems
2. Climate benefits
- Carbon‑negative materials
- Long‑term carbon storage in soil
- Potential for verified CDR credits
This dual‑impact approach creates an efficient, consolidated route to meeting environmental, regulatory and climate‑action commitments.
