Food waste

Food waste is every dollar of food that ends up in the bin instead of on a paying guest's check: product that spoiled before you used it, items over-prepped and never sold, usable trim, and what comes back on plates. It is a margin leak disguised as a chore, because the cost is already sunk (you bought it, and often cooked it) and no revenue ever comes back. The scale is enormous industry-wide: U.S. surplus food reached 73.9 million tons worth $382 billion in a recent year, with restaurants a meaningful share of it.

Waste inflates your true Food cost percentage without ever showing up as a sale, so a kitchen can hit its recipe costs on paper and still bleed margin into the trash. It traces back to three fixable things: pars set too high (see Par level), weak Portion control, and forecasting misses that leave you over-prepped one day and 86'd the next. Cutting it is one of the highest-return moves in the Back of house, because every dollar of waste removed drops almost entirely to the bottom line.

AI waste tracking is where the numbers get concrete. Computer-vision systems like Winnow weigh and identify what gets thrown out, and the company reports cutting kitchen food waste by 50% and delivering 2 to 8 percent in food-cost savings. Pair that measurement with demand forecasting that sizes prep to real covers and waste stops being something you only discover at inventory. See inventory and food cost and demand forecasting.
