Multi-Council Scaling Projection
Projected impact at 10% household penetration across target council areas
| Scenario | Councils | Households | Items/yr | Tonnage/yr | Levy Saved/yr | CO₂-e Avoided/yr | Circular Value/yr |
|---|---|---|---|---|---|---|---|
| Current Pilot | 1 (partial) | 85 | 276 | 2.4t | $407 | 4.8t | $12,420 |
| Year 1 — 5 Councils | 5 | 6,600 | 10,560 | 120t | $20,375 | 240t | $475,200 |
| Year 3 — 20 Councils | 20 | 30,000 | 48,000 | 545t | $92,536 | 1,090t | $2,160,000 |
| National — 537 Councils | 537 | 800K+ | 1.28M | 14,500t | $2.46M | 29,000t | $57.6M |
Assumptions: 10% household penetration, 1.6 items/HH/yr, 11.35 kg avg/item, 75% claim rate, $169.79/t VIC levy, 2.0 t CO₂-e/t, $45 avg item value. National uses blended levy rate.

KerbSave Contribution to Target Closure
| Scale | Annual Diversion | % of 1.4M t Gap | Significance |
|---|---|---|---|
| Current Pilot | 2.4t | 0.0002% | Proof of concept — validates methodology |
| 5 Councils (Year 1) | 120t | 0.009% | Measurable contribution — reportable to VAGO |
| 79 VIC Councils | 4,000t | 0.29% | Significant for hard waste category — fills measurement gap |
| 537 National | 14,500t | 1.04% | Material impact — one of few measurable pre-collection tools |
Gap = 12.7M tonnes total VIC waste × 11% shortfall. KerbSave captures hard waste pre-collection only — a specific category where no other measurement tool exists.
