Green Island Cement and hotels in Hong Kong repurpose oyster shells for cement production
19 August 2024China: Eaton and Langham hotels have collaborated with Green Island Cement to transform 8t of oyster shells into a sustainable cement alternative, sourcing 80% of the required limestone for cement.
Amie Lai Gor, general manager of sustainability at Great Eagle Holdings, parent company of the two hotels, said "We brought together like-minded partners to repurpose oyster shells as a sustainable raw material alternative for cement production. Our goal is to encourage more hotels and restaurants to participate, diverting more discarded oyster shells from landfills through upcycling.”
Raymond Cheung Wai-man, division manager at Green Island Cement, highlighted past challenges of separating the shells from impurities like mud and residual meat, which initially deterred the project.
Lai Gor added that future plans include working with local universities to assess the carbon reduction potential of substituting limestone with oyster shells in cement production. Despite the higher costs—tenfold compared to traditional limestone—Cheung believes that scaling up could significantly lower expenses.
