How to Calculate Circular Economy Score
The circular economy aims to eliminate waste by keeping materials in use as long as possible.
Formula
Circularity Score = (Recycled Input % + Waste Recycled %) / 2 * Lifespan Factor / 1.5
Principles
1. Design out waste: Products designed for disassembly and reuse 2. Keep products in use: Repair, refurbish, remanufacture 3. Regenerate natural systems: Return nutrients to soil
The Ellen MacArthur Foundation estimates transitioning to circular economy could reduce global CO2 by 45%.
Example Calculation
A company using 100 tons materials, 30% recycled input, 50% waste recycled, 1.5x lifespan.
- 01Circularity score: (30 + 50) / 2 * 1.5 / 1.5 = 40
- 02Virgin material: 100 * (1 - 0.30) = 70 tons
- 03Waste to landfill: 100 * (1 - 0.50) = 50 tons
- 04Material productivity: 1.5 / 0.70 = 2.14x
