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.

    Esempio Risolto

    Weekly: 5 lbs paper, 2 lbs plastic, 3 lbs glass, 0.5 lbs aluminum.

    1. Paper CO2 saved = 5 x 52 x 3.0 = 780 lbs
    2. Plastic CO2 saved = 2 x 52 x 2.5 = 260 lbs
    3. Glass CO2 saved = 3 x 52 x 0.6 = 93.6 lbs
    4. Aluminum CO2 saved = 0.5 x 52 x 10.0 = 260 lbs
    5. Total = 780 + 260 + 93.6 + 260 = 1,394 lbs CO2
    6. Equivalent trees = 1,394 / 48 = 29.0 trees
