Food Waste Rechner — Formel

How to Calculate Food Waste Impact

About 30-40% of food in the US is wasted, with enormous environmental and financial costs.

Formula

Annual Cost = Weekly Waste * 52 * Cost per lb

Environmental Impact per Pound of Wasted Food

  • CO2: ~3.8 lbs CO2e (includes production, transport, and landfill methane)
  • Water: ~108 gallons (virtual water used in production)
  • Land: ~2.5 sq ft of farmland

    • The average American wastes about 219 lbs of food per year.

    Lösungsbeispiel

    A 3-person household wasting 5 lbs of food per week at $2.50/lb average.

    1. Annual waste: 5 * 52 = 260 lbs
    2. Annual cost: 260 * $2.50 = $650
    3. CO2: 260 * 3.8 / 2,204.6 = 0.45 metric tons
    4. Water wasted: 260 * 108 = 28,080 gallons
