Core Viewpoint - The research team led by Professor Lv Jianfu from Harbin Engineering University has developed a groundbreaking technology that utilizes oysters as a biological armor for marine concrete structures, addressing both corrosion protection and ecological restoration needs in marine engineering [1][2][5]. Group 1: Technology Development - The "Integrated Key Technology for Biological Anti-Corrosion and Ecological Restoration of Marine Concrete Engineering" has been recognized as a major project under the United Nations' "Ocean Decade" initiative, with only four projects globally receiving this honor [1]. - The technology combines cement-based materials with marine organisms, creating a high-durability and ecological restoration solution that transforms marine infrastructure design [2][4]. Group 2: Ecological Benefits - The use of oysters, known as "ecosystem engineers," enhances water quality, biodiversity, and coastal protection, thereby providing multiple ecological benefits [2][5]. - The constructed "oyster reef-marine concrete engineering symbiotic system" actively improves the ecosystem, breaking the traditional conflict between marine engineering and environmental protection [5]. Group 3: Market Potential - The technology is poised to meet high-demand markets in marine engineering anti-corrosion, ecological restoration, and aquaculture, potentially establishing a "Chinese solution" for global marine ecological engineering technology [6]. - The project has already received multiple awards, including five industry patents and 27 authorized invention patents, indicating strong market interest and potential for future growth [6].

Core Viewpoint - The research team led by Professor Lv Jianfu from Harbin Engineering University has developed a groundbreaking technology that utilizes oysters to create a bio-protective layer for marine concrete structures, addressing both corrosion resistance and ecological restoration [1][2][5]. Group 1: Technology Development - The "Integrated Key Technology for Bio-Corrosion Resistance and Ecological Restoration of Marine Concrete Engineering" has been recognized as a major project under the United Nations "Decade of Ocean Science for Sustainable Development" initiative, with only four projects globally receiving this honor [1]. - The technology combines cement-based materials with marine organisms, specifically oysters, to create a high-durability and eco-restorative solution for marine infrastructure [2][4]. Group 2: Environmental Impact - Traditional marine construction methods contribute to significant carbon emissions, leading to the degradation of critical ecosystems like oyster reefs, which are essential for maintaining marine biodiversity [2]. - The new technology not only protects marine structures but also enhances ecological benefits, such as improving water quality and increasing biodiversity, thereby creating a symbiotic relationship between engineering and ecology [5][6]. Group 3: Implementation and Efficacy - The research team has developed a comprehensive solution that includes artificial induction, material design, and functional integration to attract oysters to concrete surfaces, ensuring a coverage rate of over 95% for optimal protective effects [3][4]. - The engineered oyster reefs can filter approximately 100 tons of seawater per square meter daily, significantly reducing water turbidity and nutrient levels, while also providing habitats for various marine species [5]. Group 4: Market Potential and Recognition - The technology aligns with high-demand markets for marine engineering corrosion protection, ecological restoration, and aquaculture, positioning it as a potential global standard for marine ecological engineering [6]. - The project has received multiple awards, including five industry patents and recognition in the shipbuilding and marine engineering sectors, indicating its innovative impact and market viability [6].
