The system that tracks every material, proves compliance, and calculates carbon — in real time
Every material salvaged from a construction site gets a unique QR code, GPS-verified chain-of-custody, and real-time carbon calculation. From site to verified destination — every step tracked, photographed, and audit-ready.
Built on openness and trust — fully transparent, auditable data you can stand behind.
Why this matters
Without verified tracking, you cannot prove any of these claims.
TroCymru replaces assumptions with evidence.
The Material Journey
Follow a material from the moment it is salvaged on site through to verified delivery and NRW-compliant evidence generation.
Tag & Weigh
On-Site Capture
Operative selects the scheme type, identifies the material, weighs it, and captures a departure photo. GPS coordinates are recorded automatically.
QR Generated
Unique Asset ID
A unique asset ID (TC-YYYYMMDD-XXXX) and QR code are generated. The material enters the chain-of-custody system with full traceability.
Track Journey
Site → Destination
Scan the QR at departure and arrival. Each scan records GPS, timestamp, and a photo — building an unbroken evidence trail from site to reuse hub.
Verify & Report
NRW Evidence Pack
Final verification confirms delivery. A downloadable evidence pack is generated with the full chain-of-custody, carbon data, and NRW waste carrier registration.

NRW-ready
From site to verified outcome — fully tracked
Every material is tracked from site to final destination with GPS-verified coordinates, timestamped photos, and digital chain-of-custody. This creates an unbroken evidence trail that prevents fly-tipping and satisfies NRW audit requirements.
Tagged
Material identified, weighed, and tagged with a unique QR code on site. GPS coordinates and departure photo captured automatically.
In Transit
Material leaves the site. Operative scans QR code to record departure with GPS-verified timestamp and photo of the loaded vehicle.
Delivered
Material arrives at the reuse hub, recycling facility, or recipient. Arrival scan records GPS, timestamp, and condition photo.
Verified
Final verification confirms the material reached its intended destination. Complete chain-of-custody evidence pack generated for NRW compliance.
Court-Ready Evidence Packs
Each tracked asset generates a downloadable evidence pack containing everything needed for NRW compliance and fly-tipping enforcement proceedings.
Works offline — competitive advantage for rural Wales
Many construction sites in North Wales have limited or no mobile signal. The TroCymru capture form works fully offline — materials, photos, and GPS coordinates are stored locally and sync automatically when connectivity returns.
Scheme-specific waste streams
Different types of construction work produce different waste. Select a scheme type and the capture form automatically filters to show only relevant materials.
Reduces errors on site — operatives only see materials relevant to their scheme.
Kitchen Retrofit
MDF, copper pipework, ceramic tiles, sinks, vinyl flooring, appliances

Audit-ready carbon calculations (not estimates)
Every material capture instantly calculates the carbon avoided by diverting waste from landfill. Factors are sourced from the WRAP/ICE Database and applied in real time as the operative enters the weight.
This is not offsetting.
TroCymru calculates carbon avoided through material reuse and recycling — the emissions that would have occurred if virgin materials were manufactured instead. This is measured, verifiable avoidance based on actual weights and WRAP/ICE factors, not purchased carbon credits.
Carbon Avoided
Carbon calculations use WRAP/ICE factors with processing factors included for full transparency.
View methodology
Net Avoided Carbon =
Weight (kg) x (Baseline Factor - Processing Factor)
The baseline factor represents the kgCO₂e per kg of virgin material that would be needed if the salvaged material went to landfill. The processing factor accounts for the carbon cost of sorting, cleaning, and preparing the material for reuse or recycling.
Processing factors are included for transparency — most competitors omit them.
Disposal Cost Avoided
Direct savings from landfill diversion at the current UK rate of £130.75 per tonne.
View methodology
Disposal Cost Avoided =
(Weight / 1000) x Landfill Tax per Tonne
The UK landfill tax rate for 2026 is £130.75 per tonne. This represents the direct financial saving from diverting materials from landfill. Actual savings are higher when skip hire, transport, and gate fees are included.
Example Carbon Calculations
All factors sourced from WRAP / ICE Database. Values shown are kgCO₂e per kg.
| Material | Weight | Baseline | Processing | Carbon Avoided |
|---|---|---|---|---|
| Hard Plastics (HDPE) | 100 kg | 2.53 | 0.21 | 232.0 kgCO₂e |
| Copper Pipework | 50 kg | 3.81 | 0.65 | 158.0 kgCO₂e |
| Timber (Softwood) | 200 kg | 0.46 | 0.05 | 82.0 kgCO₂e |
| Plasterboard | 300 kg | 0.12 | 0.02 | 30.0 kgCO₂e |
| Carpet & Underlay | 150 kg | 5.50 | 0.80 | 705.0 kgCO₂e |
| Fluorescent Tubes | 20 kg | 3.20 | 0.50 | 54.0 kgCO₂e |
Automated Health & Safety Compliance
Certain materials are flagged automatically with on-screen warnings when selected. The system enforces correct handling procedures before the operative can proceed.
Flagged Materials
WEEE Compliance
Built for complex, regulated waste streams
- Automatic warning banners when WEEE materials are selected
- Material-specific handling notes (mercury, refrigerant, radioactive sources)
- 7 WEEE sub-categories: tubes, detectors, fittings, lights, boilers, wiring, appliances
- Approved WEEE facility routing for fridges, freezers, and CFL lamps
Stillage & Storage
- Storage location field auto-appears for WEEE scheme captures
- Pre-filled "Stillage" hint for common WEEE storage
- Flexible free-text for skip references, drum stores, or custom locations
- Paint drum multi-site tracking — drums that move between locations
Built for the site, built for the boardroom
