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%.

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.

Does Winnow measure plate waste as well as kitchen waste?

Yes. The Vision range measures pre-consumer waste from preparation and overproduction. VisionPW uses a motion sensor camera to measure post-consumer plate waste, which is where student behaviour shows up rather than kitchen decisions.

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 does Winnow support Net Zero and impact reporting?

Winnow provides auditable data at every level, from a single hall up to group-wide reporting, covering weight, cost and CO₂e avoided. Every disposal is weighed, timestamped and photographed, so figures come from direct measurement rather than estimation.

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.
