Winnow

What It Does

Winnow addresses food waste — one of the largest and most overlooked sustainability and cost challenges in hotel food and beverage operations. The system combines AI-powered computer vision with smart scales to identify and record every item discarded in a commercial kitchen, without requiring staff to manually log anything.

How the Technology Works

The Winnow Vision unit sits above a food waste bin and uses a camera paired with machine learning models trained on thousands of food items. As staff discard food, the system automatically identifies what was thrown away, weights it, and assigns a cost value — producing a real-time record of waste by item, station, and shift.

Operational Insights

The platform's dashboard shows kitchen managers exactly which dishes are over-prepared, which ingredients are consistently wasted, and when waste peaks occur during service. This data drives practical menu and purchasing decisions — from adjusting batch sizes to removing low-popularity dishes that generate disproportionate prep waste.

Financial Case

Winnow reports that kitchens using the platform typically reduce food waste by 40–70% over time, translating directly to lower food purchasing costs and reduced waste disposal fees. For a large hotel kitchen spending hundreds of thousands on food annually, the payback period is typically under 12 months.

Hospitality Fit

Winnow is deployed in over 3,000 kitchens globally, including large hotel brands, cruise lines, and contract caterers. It fits best in high-volume food service operations where the waste signal is large enough to generate meaningful savings.
