Winnow has revealed it has saved leading hospitality groups including Hilton, Accor, Marriott, and Mandarin Oriental more than $100 million a year by using its AI-powered connected hardware that tracks food waste across kitchens.
It tracks what food is discarded, when, and why and then this data helps teams adjust production, improve processes, and run more efficient operations.
Its latest innovation, Throw & Go, allows teams to capture food waste completely touch-free, which makes measurement faster and easier, particularly in high-volume kitchens.
The firm believes it’s the chef’s themselves, not the technology though, that are leading the change.
“This milestone is a tribute to the chefs who are making food waste reduction part of their daily craft,” said Marc Zornes, CEO and co-founder of Winnow.
“They are the ones designing menus, rethinking processes, and leading their teams to cook more consciously. Our role is to give them the data to make that easier.”
Hilton, with its Green Ramadan 2025 initiative, reduced plate waste by 26% across 45 hotels in 14 countries, with support from Winnow’s AI and resources developed in partnership with UNEP West Asia while Accor, which has over 200 hotels using Winnow around the world, are collectively saving 1 meal every 6 seconds.
Emma Banks, Hilton’s vice president of food & drink strategy and development for EMEA, said: “Reducing food waste is both a moral imperative and a strategic opportunity for our industry.
“Through our partnership with Winnow, we’re empowering our chefs with the insights they need to reduce waste and lead change in kitchens around the world. These chefs are preventing 4.7M meals from being wasted each year.”
Coline Pont, chief sustainability officer at Accor, added: “At Accor, reducing food waste is a key lever in our journey towards more sustainable hospitality.
“Through our collaboration with Winnow, we empower our chefs with data-driven insights to make conscious decisions every day.
“Already, more than 200 of our hotels are equipped with Winnow technology, helping us prevent thousands of meals from being wasted and reinforcing our commitment to responsible operations across the globe.”
In total, kitchens using Winnow are preventing the waste of 28,000 tonnes of food per year – equal to two meals saved every second. This equates to more than 122,000 tonnes of CO₂e emissions avoided – or 28,000 cars taken off the road for a year, according to the US Environment Protection Agency.
