Waste

Waste is an important factor in the Food Survivability Index because every portion of food discarded represents a loss of money, nutrition, time, energy, and valuable resources. Over a lifetime of daily meals, even small amounts of unnecessary waste can accumulate into substantial financial losses and reduce the efficiency of our food supply. Waste can occur during food preparation, through spoilage caused by improper storage, from uneaten portions, or through excessive packaging. By selecting foods that can be used efficiently, preparing appropriate portions, making creative use of leftovers, and properly storing unused ingredients, we can significantly reduce waste while stretching our food budget. Minimizing waste also reduces the environmental impact associated with food production, transportation, and disposal. Within the Food Survivability Index, evaluating waste encourages us to make better use of the food we purchase, helping ensure that our meals remain economical, practical, environmentally responsible, and sustainable throughout our lives.

Food Waste Rating System

Score	Rating	Description
5	Excellent	Almost no food waste, minimal packaging, and leftovers are easily reused
4	Very Good	Less than 5% edible food waste, limited packaging, and most leftovers are saved
3	Good	5–10% edible food waste, moderate packaging, and some leftover
2	Fair	10–20% edible food waste, considerable packaging, or frequent discarded leftovers
1	Poor	20–30% edible food waste, excessive packaging, and substantial discarded food
0	Very Poor	More than 30% edible food waste, excessive packaging, and little effort to recover leftovers

Considerations

Factor	Weight	What to Evaluate
Food Preparation Waste	30%	Edible portions discarded during peeling, trimming, or preparation
Uneaten Food	40%	Food left on plates or discarded after meals
Packaging Waste	15%	Quantity of disposable containers, wrappers, and other packaging
Leftover Utilization	15%	Ability to refrigerate, freeze, or incorporate leftovers into future meals

For everyday use, I would emphasize avoidable edible food waste more than packaging waste. Packaging may be necessary to keep food safe and extend its storage life, and a small amount of packaging can prevent a much larger amount of food from being discarded.

The ultimate objective is to select meals that make the greatest possible use of the food we purchase, preserving its nutritional value while minimizing unnecessary expenses and waste.
