摘要

复合材料行业对可持续性的日益关注加速了向生物基聚合物基体的过渡。其中，聚酰胺11 （PA-11）、聚乳酸（PLA）和聚羟基烷酸酯（PHAs）作为化石基热塑性塑料的替代品显示出巨大的潜力，预计未来几年它们的工业产量将增加。这些聚合物表现出各种特性，从高机械性能到生物降解性，使它们非常适合复合材料，特别是那些用天然纤维增强的复合材料。本文综述了PA-11、PLA和pha的合成、性能及在复合材料中的应用。以全球变暖潜势（GWP）和不可再生能源使用（NREU）为参数，通过生命周期评估（LCA）对其环境影响进行了详细分析。本文对生物降解性、可回收性和工业堆肥等生命终结情景进行了评估，探讨了它们在循环经济战略中的作用。最后对未来的研究和工业应用进行了展望，包括改进处理技术、性能优化和EoL管理策略。

Bio-based and biodegradable polymers for composites: Sustainability, challenges, and future perspectives

The growing attention towards sustainability in the composites industry has accelerated the transition to bio-based polymer matrices. Among them, polyamide 11 (PA-11), polylactic acid (PLA), and polyhydroxyalkanoates (PHAs) show great potential as alternatives to fossil-based thermoplastics, and an increase in their industrial production is expected in the coming years. These polymers display various properties, ranging from high mechanical performance to biodegradability, making them well-suited for composites, particularly those reinforced with natural fibers. This review explores PA-11, PLA, and PHAs, focusing mainly on their synthesis, properties, and performances on composite materials. A detailed analysis of their environmental impact is provided through Life Cycle Assessment (LCA), using global warming potential (GWP) and non-renewable energy use (NREU) as parameters. Several End-of-Life (EoL) scenarios, including biodegradability, recyclability, and industrial composting, are assessed to explore their roles in the circular economy strategies. Perspectives on future research and industrial applications are discussed at the end, including calls for improved processing techniques, property optimization, and EoL management strategies.

期刊介绍： The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
