Case Study: Digital Twin Traceability for Chemical Recycling – GRR x Carbon Central
Located in Darwin, NT, Australia, Global Resource Recovery NT (GRR) operates one of the most advanced chemical recycling and reclamation facilities in the region. Specialising in the reclamation of glycol and amines, GRR plays a critical role in reducing reliance on virgin materials and advancing circular economy practices.
To scale its sustainability leadership, GRR needed a verifiable, transparent system to track operations and provide proof of sustainability across its value chain. Rather than relying on paper-based reporting or static declarations, GRR wanted a system that could deliver real-time data, traceable emissions insights, and tamper-proof sustainability verification.
GRR integrated Carbon Central to establish real-time emissions tracking, digital lifecycle transparency, and automated sustainability reporting.
Through this integration, GRR is now able to tokenise its recycled outputs, generating on-chain proof of sustainability and providing independently verifiable data for every batch of recycled product.
Chemical Recycling Compliance: Proving Emissions, Origin and Lifecycle Claims
Industry Context
Businesses in chemical recycling are under increasing pressure to demonstrate that environmental claims are backed by evidence. Manual data collection and fragmented systems make it difficult to track emissions, prove product origin, or ensure consistent lifecycle reporting across all production stages.
GRR’s Pain Points: Manual Reporting, Fragmented Data, Limited Audit Trails
GRR needed a solution that could:
Replace manual reporting with automated, real-time data collection.
Track emissions and material flows for each stage of the recycling process.
Ensure every batch of glycol and amines was verifiable and auditable.
Translate sustainability efforts into market trust and ESG value.
Without a structured system, proving the environmental benefit of its operations was time-consuming, inconsistent, and difficult to scale. GRR also needed to strengthen its market credibility with auditable data, particularly to differentiate its recycled products from virgin alternatives.
The Solution: How Carbon Central Delivers Real-Time Emissions, Traceability and Reporting
Onboarding and Initial Platform Setup
The onboarding process began with setting up GRR’s company profile and configuring its sustainability tracking environment within Carbon Central. Key integration points were identified across GRR’s glycol and amines reclamation workflows.
The screenshots included have had the figures altered or mocked to maintain sensitivity and protect any confidential information.
Carbon Central was then connected to GRR’s Citect system, enabling live data flow from tanks, meters, and machines. This eliminated manual data entry and created a real-time foundation for sustainability metrics.
Data fields were mapped to track:
Device-level energy and emissions data.
Material flows from input to output.
Batch-specific lifecycle data.
Supplier and transport records for traceability.
Real-Time Tracking with Digital Twins
Carbon Central configured a digital twin to mirror GRR’s operations. This digital representation allowed the platform to simulate and track each stage of chemical reclamation, with inputs from sensors, equipment, and manual entries.
The digital twin included evaporation and distillation processes, water treatment systems, and salt waste disposal. It captured heat, electricity usage, and material flow data, resulting in precise emissions calculations at the unit level.

Looking at an example of the manual data steps, information is captured about the process being tracked, and critically, the meter integration installation and calibration information.
Citect Meter Device Details
Key integrations focus on GRR’s evaporation and distillation units, core steps in the reclamation process, as well as waste management systems like water treatment and salt disposal.
Product profiles and manual data entries capture critical process information, including meter integration and calibration details. For example, one device integration captures metrics like heat, electricity, and tracked product data.
These inputs undergo calculations within Carbon Central, resulting in total emissions data for each tracked device.

Batch Management: End-to-End Chain of Custody for Glycol and Amines
With batch management, GRR could track every recycled batch of glycol and amines from input to output.
Each batch included:
Chemical composition.
Supplier origin.
Transport emissions.
Attached lifecycle documents and compliance records.
This provided a fully auditable history of every recycled product, reinforcing sustainability claims with transparent, verifiable data.
Tokenised Digital Certificates: On-Chain Proof of Sustainability
GRR became one of the first companies to turn a batch of recycled amines into a digital sustainability token using Carbon Central. Each token represented 1,000 litres of product and acted like a secure digital certificate that proved the batch was genuinely sustainable.
The tokens included:
Where the materials came from.
Data from the machines that processed the batch.
A locked, tamper-proof record showing its environmental impact.
Your Tokens feature
These tokens are stored on the blockchain and can be viewed through Carbon Central’s Trust Chain. That means investors, customers, or regulators can check the data themselves, giving GRR a transparent digital trail for every sustainability claim it makes.

Automated Emissions Reporting and Guarantee of Origin Evidence
Carbon Central enabled GRR to generate customised, batch-specific sustainability reports. These reports contain real-time emissions data, lifecycle records, and benchmarking insights that compare recycled outputs to conventional alternatives.
Reports are formatted for use in investor briefings, customer declarations, and voluntary ESG disclosures — all backed by on-chain data.
Guarantee of Origin Certificate
Whether for compliance reporting, investor disclosures, or customer transparency, Carbon Central ensures that GRR’s sustainability efforts are both credible and actionable.
Outcomes: Measurable Carbon Savings, Market Trust, Lower Admin Overhead
Carbon Central transformed GRR’s approach to sustainability:
Replaced manual reporting with real-time automation.
Increased confidence in emissions data and environmental claims.
Made every recycled batch traceable, auditable, and tokenised.
GRR can now:
Demonstrate measurable carbon savings.
Strengthen customer and investor trust.
Reduce administrative burden while improving accuracy.
The integration of blockchain-based tokenisation has turned sustainability data into a strategic asset, improving ESG positioning and opening new revenue opportunities through verifiable environmental claims.
From Promises to Proof: Digital Twins + Tokenisation in Chemical Recycling
GRR’s journey shows how digital tools can unlock the full value of sustainability. By integrating Carbon Central, GRR turned recycling data into market credibility, proof of impact, and business value.
With digital twins, tokenised sustainability records, and automated reporting, GRR is leading the shift from promises to proof — and setting a new benchmark in the chemical recycling industry.
What’s Next: Scaling Tokenisation, Mainnet Expansion, Deeper Digital Twins
Following the successful tokenisation of recycled amines, GRR is scaling tokenisation for glycol and continuing to strengthen its infrastructure.
Future plans include expanding mainnet transactions, enhancing digital twin precision, and streamlining third-party data access through Carbon Central’s Trust Chain.
This marks a pivotal moment in sustainable resource recovery: where carbon impact is measured in real time, verified on-chain, and leveraged for growth.
