The average US household throws away roughly a third of the food they buy. At typical grocery prices, that is $1,500+ a year for a family of four and about 500 lb of organic matter heading to the landfill, where it rots without oxygen and releases methane.
Two highest-leverage fixes: plan meals before shopping (cuts impulse buys that spoil), and set up any kind of compost stream — backyard bin, municipal collection, or a countertop unit. Composted scraps become soil. Landfilled scraps become methane.
annual_lb = weekly_lb × 52
annual_$ wasted = (annual_lb ÷ annual_grocery_lb) × annual_grocery_$
annual_CO₂e (kg) = annual_lb × 1.5
car_miles_equiv = CO₂e_kg ÷ 0.4
compostable = annual_lb × 0.70
