Description

Marriott International has integrated Winnow’s AI-enabled food waste tracking technology in over 50 of its hotels in the UK and Ireland, particularly in London. This initiative is part of Marriott's commitment to sustainability and operational efficiency, addressing food wastage issues that affect both the environment and costs. Winnow's technology offers precise data and insights for better inventory and meal preparation decisions, leading to significant reductions in food waste and cost savings. This move not only minimizes Marriott's environmental footprint but also sets a sustainability benchmark for the hospitality industry.

Impact & Result

This new collaboration will play a crucial role in helping Marriott International achieve its ambitious 2025 goal of reducing food waste by 50%, with 2016 serving as the reference year. By working together with key partners, Marriott will implement innovative strategies and solutions aimed at significantly cutting food waste across its properties.

Solution Spotlight

Using a camera, a set of smart scales and the same type of machine learning technology found in autonomous vehicles, Winnow Vision ‘learns’ to recognise different foods being thrown in the bin and calculates the financial and environment cost of this discarded food to commercial kitchens. Businesses and chefs can then adjust their food purchasing decisions accordingly, reducing their spending and tackling a fundamental problem of food waste: overproduction. Winnow has helped commercial kitchens save more than $33 million in annualised food costs which equates to preventing over 23 million meals going in the bin. The new, AI-powered Winnow Vision is already installed in over 75 kitchens and the technology will be rolled out to hundreds more this year.
