Core Viewpoint - The article discusses the ecological risks associated with biodegradable plastics, despite their perceived environmental benefits, and emphasizes the need for strategies to mitigate these risks [1][3]. Group 1: Ecological Risks of Biodegradable Plastics - Biodegradable plastics, while seen as eco-friendly alternatives to traditional plastics, can release microplastics and nanoplastics that pose potential health risks [1][3]. - The degradation of biodegradable plastics can lead to the release of diverse oligomers, which are persistent organic pollutants, raising concerns about their adverse effects on ecosystems [4]. - Chemicals released from biodegradable plastics, such as phthalates and bisphenol A, have been shown to disrupt cellular metabolism and can have genetic, reproductive, and immunotoxic effects on organisms [5]. Group 2: Production and Demand Trends - The global demand for biodegradable plastics is increasing, with production expected to reach 2.47 million tons in 2024 and 5.73 million tons by 2029 [2]. Group 3: Mitigation Strategies - To reduce the potential risks associated with biodegradable plastics, collaboration among research institutions, companies, and policymakers is essential [5]. - Key strategies include identifying the sources and degradation pathways of toxic oligomers, developing biodegradable plastics with controllable and complete degradation capabilities, and redesigning the structure of biodegradable plastics for safer alternatives [5][6].
