Frequently Asked Questions 

What is Winnow?

Winnow is the most widely deployed AI food waste prevention system for commercial kitchens. A camera and connected scale automatically identify and weigh every item thrown away, then turn that data into daily reports chefs use to adjust purchasing, menus, and portions. Winnow operates in over 3,500 sites across 94 countries, with customers saving over $100 million per year. Founded in 2013, Winnow is a Certified B Corporation and is trusted by Hilton, Marriott, Accor, IHG, IKEA, Mandarin Oriental, and Iberostar.

What is Throw & Go?

Throw & Go is Winnow’s fully automated waste tracking mode. Kitchen staff throw food away exactly as they normally would, no scanning, no selecting categories on a screen, no extra steps. The AI handles identification and recording entirely on its own. It was designed for busy, high-volume kitchens where any additional step slows service down. Unlike manual food waste tracking, which requires staff to weigh, log, and categorise each item, Throw & Go removes every point of friction. Adoption rates are higher because there is nothing to learn and nothing to remember. For hotel groups and contract caterers evaluating alternatives to manual tracking. Throw & Go is why Winnow maintains high capture rates in kitchens where manual tracking systems are routinely skipped during busy service. Because there are no extra steps, staff compliance is not a barrier.

We already track food waste, why use Winnow?

Manual food waste tracking relies on busy staff weighing and logging waste during service, it's time-consuming, often incomplete, and the data rarely gets acted on. Winnow's AI automates the entire process: no scanning, no manual input, just accurate data with little or no effort from your team. With Throw & Go, the full waste stream is captured, photo-evidenced, and turned into daily insights chefs can act on. Sites typically cut food costs by 2–8% and halve food waste, with 100-day onboarding and ongoing coaching from Winnow's culinary advisors, including Zero Waste Culinary Advisor Chef Vojtech Vegh.

 How quickly can Winnow be installed and deployed?

Winnow is designed for quick setup with accurate data from day one. The hardware is compact and straightforward to install. Winnow's AI is pre-trained on 500 million food waste images with sector-specific menu templates, so there is no lengthy calibration period. Each site receives a 100-day kitchen coaching programme, baseline data validation by a Winnow auditor, and ongoing monthly skill sessions. For enterprise clients, Winnow follows a pilot-to-rollout model, Iberostar, for example, is scaling Winnow to over 100 hotels. Deployments are phased to minimise disruption while building internal confidence with real data.
