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
