央视网消息：海洋塑料污染是全球性难题，如何破解收集难、处置难、监管难？浙江通过"政府引导+企业主导+产业协同+公众参与"的联动机制，创 新推出"蓝色循环"模式，让渔民从"海洋索取者"变成"海洋守护者"。2023年，这一模式荣获联合国"地球卫士奖"。它如何实现生态与经济的双赢？记者深 入浙江台州大陈岛，探访这场"蓝色革命"的生动实践。 距离浙江台州市区52公里的大陈岛是国家一级渔港，也是旅游胜地。清晨，大陈岛的薄雾还未散尽，61岁的黄海滨已和伙伴们驾船出海，在起伏的浪涛 中，开始了"海洋美容师"的一天，而这正是"蓝色循环"项目带来的新营生，他和搭档们已经干了好几年。 从"污染之痛"到"治理之变" 台州700公里海岸线曾饱受垃圾困扰，每一艘渔船年均产生或打捞500公斤海洋塑料废弃物，岸滩腥臭难闻，岛上十多名环卫工力不从心。小岛远离陆地， 垃圾外运成本高昂，治理陷入僵局。如何让渔民主动带回海上垃圾，并确保岸滩垃圾有人清理？2019年，浙江省政府尝试在机制上有所突破，和浙江蓝景 科技有限公司共同推出"蓝色循环"治理模式，让垃圾变财富。 "生态账"也是"民心账" 当地政府以"高价回收+公益岗位"双轮驱动，吸引岛上几十名 ...

Core Viewpoint - The "Net Plastic from the Source" seminar aims to address marine plastic pollution through effective strategies and practices, focusing on source reduction and reusable models to enhance marine ecological protection [1] Group 1: Marine Plastic Pollution Initiatives - The "Net Plastic Nature Guarding Ocean" project targets remote beaches and islands in Guangdong, Fujian, Hainan, and Zhejiang, organizing beach clean-up activities and community training to enhance environmental awareness [2] - From 2024 to 2025, the project plans to conduct 24 clean-up events, mobilizing over 1,500 volunteers to collect more than 4,200 kilograms of marine debris [2] - The project collaborates with local partners to amplify the impact of plastic reduction efforts and promote marine environmental protection [2][3] Group 2: Local Collaboration and Knowledge Sharing - A roundtable discussion highlighted local responses to global plastic pollution initiatives, sharing experiences from various organizations involved in marine protection [3] - Representatives discussed integrating local case studies into international narratives to strengthen grassroots voices in global negotiations [4] Group 3: Reusable Solutions and Economic Opportunities - The Ellen MacArthur Foundation emphasizes the importance of reuse in the circular economy, advocating for policies that promote reusable packaging [5] - The foundation notes that reuse is transitioning from niche to mainstream, with various brands adopting refillable and bulk sales models [5] - A case study on reusable cups in urban areas shows a 60% willingness among surveyed businesses to adopt this model, with a pilot project set to launch in August [6][8] Group 4: Sustainable Practices in Tourism - Qingping Island faces significant plastic waste challenges due to tourism, with over 30% of plastic waste from beverage packaging during peak seasons [10] - The local community is actively pursuing a "zero waste" approach, demonstrating a commitment to sustainable development [10][11] - The integration of tourism and environmental protection aims to spread ecological awareness among visitors, fostering a culture of responsible travel [12]

Core Viewpoint - The research team from Central South University, in collaboration with other universities, has developed an innovative microbubble flotation technology for marine plastic pollution management, providing a new approach to tackle the growing issue of microplastic contamination in oceans [1][2]. Group 1: Research Findings - The study reveals a bidirectional regulatory mechanism of algal extracellular polymers in the microplastic flotation process, enhancing the stability of microbubbles and precisely regulating the surface characteristics of microplastics [1]. - Compared to conventional flotation methods, microbubble flotation shows potential due to its small size and high stability, although complex interfacial interactions in marine environments pose significant challenges [1][2]. - Algal extracellular polymers induce hydrophilization of microplastic surfaces, weakening the hydrophobic interactions between microplastics and microbubbles, which significantly reduces the efficiency of conventional flotation methods in removing microplastics from seawater [2]. Group 2: Implications for Technology - The findings provide new insights into interfacial interactions in marine microplastic flotation and establish a theoretical foundation for the application of microbubble flotation technology in addressing marine microplastic pollution [2].
