Winnow AI Food Waste Reduction: A Case of Marriott UK, Ireland and Nordics

Marriott UK, Ireland, and Nordics partnered with Winnow to implement AI food waste reduction technology in 53 hotels, achieving a 25% reduction in food waste within six months. Winnow’s system uses computer vision and weighing scales to identify discarded food, assign costs, and generate real-time data and detailed reports. These insights help chefs and managers adjust menus and portion sizes, saving up to 8% on food purchasing. Staff receive coaching to maximize ingredient use and promote zero waste. However, the technology cannot yet process mixed food types, requiring manual separation by staff until further improvements are made.

万豪酒店集团英国、爱尔兰及北欧区域（Marriott UK, Ireland, and Nordics）与 Winnow 达成合作，在其 53 家酒店引入了 AI 厨余垃圾减量技术，并在六个月内实现了厨余垃圾减少 25% 的显著成效。Winnow 的系统利用计算机视觉技术和电子称重系统来识别废弃食品、评估其成本，并生成实时数据和详细报告。这些数据洞察有助于厨师和管理人员调整菜单和菜品分量，从而节省高达 8% 的食品采购成本。此外，员工还接受了相关指导，以最大化提高食材利用率并倡导“零浪费”理念。然而，该技术目前尚无法自动处理混合类食品，在技术进一步完善之前，仍需要员工进行手动分类。
