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