## How Recycling Reduces Emissions
Recycling avoids emissions from manufacturing new materials from raw resources.
### Approximate CO2 Savings Per Pound Recycled
- **Paper/Cardboard**: ~3.0 lbs CO2/lb
- **Plastic**: ~2.5 lbs CO2/lb
- **Glass**: ~0.6 lbs CO2/lb
- **Aluminum**: ~10.0 lbs CO2/lb
Aluminum recycling is the most impactful per pound because smelting new aluminum is extremely energy-intensive.

计算示例
Weekly: 5 lbs paper, 2 lbs plastic, 3 lbs glass, 0.5 lbs aluminum.
- Paper CO2 saved = 5 x 52 x 3.0 = 780 lbs
- Plastic CO2 saved = 2 x 52 x 2.5 = 260 lbs
- Glass CO2 saved = 3 x 52 x 0.6 = 93.6 lbs
- Aluminum CO2 saved = 0.5 x 52 x 10.0 = 260 lbs
- Total = 780 + 260 + 93.6 + 260 = 1,394 lbs CO2
- Equivalent trees = 1,394 / 48 = 29.0 trees
