Case Study: London Marriott Hotel Canary Wharf achieves 67% reduction in food waste with Winnow

London Marriott Hotel Canary Wharf achieves a 67% Reduction in Food Waste with Winnow in 6 Months

London Marriott Hotel Canary Wharf, a busy hotel in London’s financial district, wanted to strengthen its sustainability efforts and support Marriott’s Mission Zero goals. The hotel faced the challenge of reducing food waste across complex kitchen operations while maintaining service for corporate and international guests. It partnered with Winnow and used its AI-powered food waste analytics platform to identify waste patterns and improve kitchen decisions.

Winnow helped the hotel adjust buffet offerings, portioning, and training based on daily waste data, driving a 67% reduction in food waste within 6 months. The results included 33 tons of CO2e saved annually, £14,000 in annual food waste cost reduction, 20,000 meals saved per year, and 17,000 meals kept from landfill. With Winnow, the hotel also inspired broader sustainability changes across the property and achieved Green Key certification.
