Waste log is a record used by a restaurant or food-production operation to document food and material that is discarded. It helps identify recurring losses, measure the cost of waste and support corrective action in purchasing, storage, preparation, portioning and production planning.
Managers review records by ingredient, station, shift and reason to identify patterns. Repeated spoilage may indicate purchasing or storage problems, while overproduction may signal inaccurate forecasting or batch sizes. Trim waste can be reviewed against yield standards and suitable secondary uses.
Example: a kitchen records 3 kg of salmon trim and 2 kg of expired cream in one week. The chef reviews the salmon fabrication standard and adjusts cream ordering and stock rotation.
Waste log records waste as it occurs. Waste audit is a more systematic review that measures and analyses waste streams over a defined period to identify improvement opportunities.
Chef’s tip: record waste consistently and include the reason, not just the quantity. Use the data to adjust purchasing, prep levels and recipes rather than treating the log as a disciplinary tool.
