Case Study
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.

Case Study
Hong Kong’s high seafood consumption generates significant oyster shell waste, straining landfills and contributing to greenhouse gas emissions. In response, the Great Eagle Group partnered with Green Island Cement to launch the world’s first Oyster Shell Upcycling Programme in 2023. This initiative repurposes discarded oyster shells—rich in limestone—into sustainable cement, reducing reliance on carbon-intensive mining and landfill waste. Since its launch, nine tonnes of shells from Eaton HK and The Langham have been upcycled. However, challenges include the cost and labor of cleaning shells, storage and transport logistics, and the need for greater employee and public awareness to expand participation.

Case Study
Swire Hotels in Hong Kong have implemented innovative sustainability initiatives to address growing environmental concerns among travelers. At EAST Hong Kong, the restaurant FEAST uses the ORCA food waste recycling machine, which decomposes food waste into liquid for safe disposal and renewable energy generation, diverting nearly 12,000 kg of waste from landfills in 2023. The Upper House created a zero-waste Christmas tree from upcycled plastic bottles and glass, later transforming it into furniture auctioned for charity. Despite these impactful efforts, challenges remain in staff awareness and public promotion, suggesting a need for better education and communication about sustainability practices.
