The Carbon Removers are utilizing an innovative pathway to capture biogenic CO2 from waste streams from industrial sources such as distilleries, for permanent utilization and sequestration. Their capture facilities in Scotland are designed for modular deployment at emitter sites, allowing them to quickly get up and running.Once captured, the CO2 is then transported by truck to be sequestered. Today, this CO2 is durably mineralized into building aggregates. Over time, The Carbon Removers plans to scale up their capture operations, and permanently sequester biogenic CO2 in storage sites such as the offshore Project Greensand in the North Sea.
From day one, The Carbon Removers wanted their operations to be transparent, backing up high-integrity credit origination. They also wanted repeatable, streamlined workflows that got them to reporting and credit issuances quickly. They recognized that they would need a robust, transparent system for Measurement, Reporting, and Verification (MRV) to ensure every tonne removed was well-accounted for – Mangrove was the perfect partner to make this happen.
The Carbon Removers partnered with Mangrove to implement a comprehensive MRV solution that captures high-resolution operational measurements, quantifies the net carbon deliveries in accordance with Puro’s methodology, and supports transparent, audit-ready reporting.
The Carbon Removers’ operations generate diverse data types across all their project stages - flow rates, composition analysis, transport trips, energy usage and more. Without a proper MRV setup, the amount of data being produced from these sources could have quickly become overwhelming.
Mangrove’s MRV platform ingests and organizes these diverse data streams into a unified pipeline. The platform is integrated with The Carbon Removers’ on-site SCADA systems, enabling real-time ingestion of timestamped meter measurements for various aspects of the capture operations.
Beyond directly-metered data, The Carbon Removers processes also include truck deliveries of CO2. Real-time metadata such as distances is needed for accurate accounting of transport emissions, as well as reconciliation of deliveries to what left the factory gate. Unstructured data such as CO2 purity certificates and weighscale tickets back up the transport data. It can be challenging for delivery drivers to layer accurate data collection on top of all their operational responsibilities – Mangrove provides a simple way for every delivery to be tracked by an immutable unique tracking unit, improving it quickly through an iterative feedback loop with the drivers.
In accordance with the Puro Carbonated Materials methodology, Mangrove’s configurable quantification engine calculates net carbon removal per batch of CO2 delivered for sequestration. Each net tonne stored is accounted for after adjusting for capture efficiency as well as emissions from operational activities.
This ongoing quantification results in a verifiable ledger of net tonnes sequestered, associated with geolocation information. This level of detail supports both compliance-grade auditing and performance benchmarking.
Mangrove’s system packages quantification outputs into stakeholder-ready formats: API feeds for registries, auditor dashboards, buyer portals, and standardized reporting for the reporting and origination of Puro CORCs.The Carbon Removers also uses the platform to report their activity to industry ledgers such as the Northern Trust’s Carbon Ecosystem, which connects institutional buyers with carbon project developers.
The centralized repository of measurements and quantification in Mangrove ensures The Carbon Removers does not need to duplicate or re-calculate data in order to produce new reporting. From the same ledger, data can be transferred through API to a registry of choice; a user can log in to a portal to view an array of backing evidence; or a configured spreadsheet report could be generated for offline review.
“With Mangrove’s MRV in place, we’ve streamlined our reporting obligations and reduced lag time between project operations and independent verification. It’s a vital tool in making CDR both scalable and trustworthy.” explained Sanjay Parekh, CCO at The Carbon Removers.
Through the process of operationalizing MRV, both the Mangrove and The Carbon Removers teams came away with several key learnings:
Best-in-class MRV cannot be accomplished with just software alone, especially with a process like The Carbon Removers’ that is spread across many capture sites and connected by different transport legs. Mangrove and TCR worked closely to ensure that operators in the field understood how their specific tasks contribute to transparent reporting, and compiled standard operating procedures that contribute to a well-documented monitoring plan.
TCR’s credibility with high-quality carbon buyers is underpinned by their MRV practices. By making robust MRV a core part of their offering, TCR has successfully closed offtake agreements and met rigorous due diligence standards.
Operationalizing MRV for The Carbon Removers began with identifying where measurements and evidence already existed, and what could immediately be digitized. Not every data parameter across the project needed to be metered from day one or directly integrated into Mangrove - even regular system exports or data requests could be used to kick off data collection. This prevented over-engineering at the early stages, and allowed both sides to use regular check-ins to discuss a path towards higher automation over time.
Since deploying Mangrove, The Carbon Removers has:
TCR’s ambitious roadmap includes new facilities across the UK and in the Nordics, commercializing through new registries such as Isometric. Having Mangrove’s platform at work gives The Carbon Removers the assurance that they can easily roll out the core MRV workflows to new sites under new value streams, while adapting to local deployment and policy contexts.
Whether expanding into new biomass types or pursuing new certification standards, TCR can rely on Mangrove to power a unified, flexible MRV infrastructure — ensuring that every tonne removed is not just stored, but proven.
