Recycling Savings Calculator — Formula
## How to Calculate Recycling Savings
Recycling saves energy compared to manufacturing from raw materials.
### Energy Savings (kWh per lb recycled)
- **Aluminum**: 7.0 kWh/lb (95% energy savings vs virgin)
- **Paper**: 2.5 kWh/lb (60% savings)
- **Glass**: 0.5 kWh/lb (30% savings)
- **Plastic**: 3.0 kWh/lb (70% savings)
### Formula
**Energy Saved = Weight * kWh per lb * 52 weeks**

Exemplo Resolvido
A household recycling 1 lb aluminum, 5 lbs paper, 3 lbs glass, 2 lbs plastic per week.
- Aluminum: 1 * 52 * 7.0 = 364 kWh
- Paper: 5 * 52 * 2.5 = 650 kWh
- Glass: 3 * 52 * 0.5 = 78 kWh
- Plastic: 2 * 52 * 3.0 = 312 kWh
- Total: 364 + 650 + 78 + 312 = 1,404 kWh saved
