With the increasing global population, the disposal of waste has risen, especially over the last century. The Environmental Protection Agency (EPA) reported that 11 million tons of textile-related waste were landfilled in the USA in 2018, and this amount is projected to increase to 4.5 billion tons by 2040. Bio-based polymers have gained attention due to their remarkable properties. The most important biodegradable polymers include PLA, PHA, PHB, PCL, PBS, bamboo fibers, and banana fibers. Global biopolymer production capacity is expected to rise significantly, from around 2.18 million tons in 2023 to approximately 7.43 million tons by 2028. In the textile industry, the linear waste model presents numerous challenges, such as environmental damage and resource shortages. Shifting from a linear to a circular economy is essential to address these issues. Reducing, reusing, and recycling are the three key actions and strategies that form the foundation of the circular economy. This paper presents the current state of knowledge and technological advancements in biodegradable polymers in the textile industry, along with their products and applications. The study explores the cost-effectiveness, limitations, opportunities, and advancements in their manufacturing technologies. Biodegradable polymers in the textile sector are regarded as green alternatives to non-biodegradable polymers.
随着全球人口的不断增加，废物的处理量也在上升，尤其是在过去的一个世纪。美国环境保护局（EPA）报告称，2018年美国有1100万吨与纺织品相关的废物被填埋，预计到2040年这一数量将增至45亿吨。生物基聚合物因其卓越的性能而受到关注。最重要的可生物降解聚合物包括聚乳酸（PLA）、聚羟基脂肪酸酯（PHA）、聚羟基丁酸酯（PHB）、聚己内酯（PCL）、聚丁二酸丁二醇酯（PBS）、竹纤维和香蕉纤维。全球生物聚合物的生产能力预计将大幅提高，从2023年的约218万吨增至2028年的约743万吨。在纺织行业，线性废物模式带来了诸多挑战，如环境破坏和资源短缺。从线性经济向循环经济转变对于解决这些问题至关重要。减少、再利用和回收是构成循环经济基础的三项关键行动和策略。本文介绍了纺织行业中可生物降解聚合物的知识现状和技术进步，以及它们的产品和应用。该研究探讨了其制造技术的成本效益、局限性、机遇和进步。纺织领域的可生物降解聚合物被视为不可生物降解聚合物的绿色替代品。
