Circular Economy Calculator
Measure your circular economy score by evaluating material reuse, recycling, product lifespan extension, and waste reduction.
Circularity Score
40.0 /100
Circularity Score vs Total Materials Used
公式
## 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%.
计算示例
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
常见问题
What is the circular economy?
The circular economy is an alternative to the traditional linear take-make-waste model. It aims to keep materials in circulation through reuse, repair, refurbishment, and recycling, minimizing waste and virgin resource extraction.
How does circular economy differ from recycling?
Recycling is just one component. The circular economy prioritizes reducing consumption, extending product life through repair and reuse, and designing products for disassembly. Recycling is a last resort before disposal.
What industries are adopting circular economy?
Fashion (rental, resale), electronics (refurbishment), packaging (reusable containers), construction (material reuse), and automotive (remanufactured parts) are leading adopters.
