Food waste tracking is the practice of recording food that is discarded, along with the reason and the cost. Reasons typically include spoilage, over-preparation, plate waste, customer returns, trimming and cooking errors.
Staff log waste in a book, an app or the inventory system, selecting the item, amount and reason. Some venues also weigh bins or use a connected scale. The data is totalled by item and reason, then compared with sales and purchases to show where money is being lost.
Cafés, restaurants, bakeries and fast-food outlets use waste data to adjust prep quantities, change par levels, rework menus and tighten ordering. Retail grocers use it to time markdowns and reduce what is thrown out at the end of the day. Many also use it to support their own sustainability goals.
The common pitfall is incomplete logging. Staff skip it when busy, and waste that is not logged looks like unexplained stock variance. Clear categories, an easy method and a manager who reviews the figures weekly make the data usable.
Waste is a direct cost, often hidden in food cost percentages, so making it visible is typically one of the quickest ways to improve margin. Small, regular records usually beat occasional detailed audits.
