The World Sustainable Hospitality Alliance (the Alliance) – a powerful coalition of over 50 united members, which collectively tackle pressing challenges affecting our planet, people, and places – is thrilled to welcome the world-leading AI-driven food waste solution, Winnow, to its global portfolio of members.

Winnow’s innovative AI solutions have been widely adopted by leading hospitality brands such as Hilton, Marriott, IHG, Accor, Compass Group, ISS, and Iberostar. The company recently secured series C funding which will enable the organisation to continue building its technology, making Winnow’s AI faster and smarter whilst expanding its global reach.

Winnow’s technology harnesses the power of computer vision to identify wasted food items in real-time. Winnow’s analytics tools then help teams pinpoint waste areas, giving them insights to make operational improvements and cut waste in half. Typically a commercial kitchen wastes 5%-15% of the food it buys.1

A kitchen using Winnow would therefore expect to cut food purchasing costs by 2%-8% – a material saving given fluctuating inflation and margin pressures on operators. Winnow is viewed as the number one solution provider in this space with operations in 80+ countries over 2,700 locations.

Winnow’s AI-driven food waste solutions have demonstrated significant success in reducing waste and costs for clients. Partners of Winnow are saving $70 million in food costs each year and preventing 50 million meals from entering landfill.

Glenn Mandziuk, CEO of the World Sustainable Hospitality Alliance, comments on the addition of Winnow to the Alliance’s network:

“Food waste is a major global issue for our industry. WWF estimates that up to 10% of global greenhouse gas emissions can be attributed to food loss and waste, with Winnow estimating that in excess of $100bn worth of food is wasted each year in the hospitality sector alone. Having Winnow on board at the Alliance significantly strengthens our ability to tackle this major issue that will only become more problematic if not addressed now.”

Marc Zornes, CEO and Co-founder of Winnow says:

“Joining the World Sustainable Hospitality Alliance is a significant milestone for Winnow. Our mission has always been to tackle food waste on a global scale, and being part of this powerful coalition will enable us to amplify our impact. Together with the Alliance’s network, we can drive even greater change, helping the hospitality industry become more sustainable and resilient. We are excited to collaborate with like-minded leaders to build a future where food is valued and not wasted.”
