What food cost savings can universities expect?

Catering teams using Winnow typically achieve a 2 to 8% reduction in food costs by cutting avoidable food waste. Savings come from better forecasting, tighter portion control and clear visibility of where waste happens.

Does reducing waste mean smaller portions or a narrower menu?

No. Most of the reduction comes from producing the right amount rather than serving something different. Winnow shows what comes back untouched, so production matches demand while the student offer stays as it is.

How long does it take to install?

Winnow is built to go live without a technician or an IT project. Units assemble in about 15 minutes and can be pole mounted, wall mounted or free standing. The AI is pre-trained, so a site produces accurate data from day one.

Does Winnow work if our catering is run by a contractor?

Yes. Winnow runs in both in-house and contractor-operated catering, and reports into one Winnow Hub either way, so the institution keeps visibility of waste and cost across the estate regardless of who operates the kitchen.

How does Winnow work in a university dining hall?

A camera photographs food as it enters the bin and a connected scale weighs it. Winnow's AI identifies the item and logs its weight, cost and reason, with no action from your team. VisionPW adds plate waste measurement in halls using a motion sensor camera.

Winnow is the leading AI food waste system for commercial kitchens, deployed in more locations than any other. It measures what a kitchen throws away automatically and forecasts how much to produce. Winnow runs in 3,500+ locations in 90+ countries, where clients typically cut food costs 2 to 8%.

Plate waste measurement in halls

VisionPW uses a motion sensor camera to measure what students leave on the plate. Kitchen data tells you what you over-produced; plate waste tells you what students did not want.

Production guidance through term-time swings

Demand shifts sharply across the academic calendar, from move-in week to exam season, and no spreadsheet survives it. Winnow shows what came back untouched at each service, so production follows real attendance.
