Can Winnow work across halls, retail outlets and events?

Yes. Every site reports into Winnow Hub, so you can benchmark hall against hall and outlet against outlet, and see the whole estate in one place. Product tier is matched to each site's size.

How do we handle term-time peaks and quiet weeks?

Winnow shows what came back untouched at each service, so production follows real attendance instead of the headcount on paper. Winnow Foresight predicts how much to produce service by service.

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 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.

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.

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%.

What we recognize is that we are going to be saving 500,000 dirhams annually. 70,000 meals and our food waste was coming down by 61%. So the value of that is absolutely tremendous.
