The Formulas
CIRCIL_Levy_Clean = Weight_tonnes × $5/tonne
CIRCIL_Levy_Mixed = Weight_tonnes × $60/tonne
Carbon_Dividend = Weight_tonnes × 0.75 × $135 USD × 1.38 FX
Savings_vs_Mixed = (Weight_tonnes × $55/tonne spread)
CIRCIL Levy Savings (Per Load, Clean vs Mixed)
| Bin | Weight | Clean ($5/t) | Mixed ($60/t) | Savings |
|---|---|---|---|---|
| 20-yd | 2.66 t | $13.30 | $159.60 | $146.30 |
| 30-yd | 3.99 t | $19.95 | $239.40 | $219.45 |
| 40-yd | 5.32 t | $26.60 | $319.20 | $292.60 |

Why the Math Holds
Wood waste density is benchmarked at 174 kg/m³ (ASTM compacted). CIRCIL Levy rates are Ontario regulatory: $5/tonne clean (Class 146), $60/tonne mixed. Carbon Dividend yield is 0.75t CO₂e per dry tonne of biomass feedstock — conservative market rate $135 USD/tonne at 1.38 USD/CAD FX.
