Building Sustainability with Oysters: A Case of the Great Eagle Group

Abstract

<p align="justify">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. <p align="justify">香港庞大的海鲜消费量产生了大量的蚝壳（牡蛎壳）垃圾，这不仅给垃圾填埋场带来沉重负担，也加剧了温室气体排放。为此，鹰君集团（Great Eagle Group）与青洲英泥（Green Island Cement）于 2023 年合作推出了全球首个“蚝壳循环再造计划”（Oyster Shell Upcycling Programme）。该项目将富含石灰石的废弃蚝壳重新利用，转化为可持续水泥，从而减少对高碳排开采活动的依赖，并减少填埋垃圾。自启动以来，已有来自香港逸东酒店（Eaton HK）和香港朗廷酒店（The Langham）的 9 吨蚝壳被循环再造。然而，该计划也面临着挑战，包括清洗蚝壳的资金与人工成本、仓储和运输物流难题，以及需要进一步提高员工和公众的环保意识以扩大参与度。
