Loop Methodology
How we calculate impact, verify loops, and ensure community value. Every number is real. Every credit is backed by physical waste.
Physical First
No estimates. No projections. Every credit represents real waste diverted and measured.
Full Traceability
Every batch tracked from collection to processing. Cryptographic proofs anchor the chain.
Local Value
60% of revenue stays in the community. No extraction to distant shareholders.
Carbon Calculation Methodology
Food Waste → Biogas Loop
Avoided Emissions
- Landfill methane: 0.74 tCO₂e/tonne
- Grid displacement: 0.233 kgCO₂/kWh
- Transport reduction: 0.12 kgCO₂/tonne-km
Value Streams
- Electricity: £0.15/kWh
- Heat: £0.04/kWh
- Digestate: £15-25/tonne
- GIRM credits: £45/tCO₂e
UCO → Biodiesel Loop
Avoided Emissions
- Fossil diesel: 3.16 kgCO₂e/L
- UCO lifecycle: -2.89 kgCO₂e/L net
- 91.5% GHG reduction vs diesel
Value Streams
- Biodiesel: £1.20-1.40/L
- Glycerol: £200-400/tonne
- RTFO credits: £0.30-0.50/L
- GIRM credits: £45/tCO₂e
