Abstract

Global production of synthetic polymers such as plastics is nearly 390 million tons/year, which is creating enormous challenges on a number of frontiers including environment, sustainable development and health. The non-degradability of plastics and petrochemical-based polymers is a huge environmental crisis despite being an industry with billions of dollars share in global economy. Water pollution due to synthetic plastics and related products is evident from the fact that 7 million tons of land based plastic debris enters oceans and water bodies annually endangering the sea life which is not only a concern for the aquatic environment but also for the sea food industry and eventually to human health. Eco-friendly and sustainable polymers from a number of living organisms can be used as an alternative to synthetic polymers. Biopolymers such as starch, cellulose, pectin, keratin, chitin, gelatin and polyhydroxyalkanoates can be obtained from natural biomass sources. All these biopolymers exhibit suitable physiochemical, thermal and mechanical properties that make them suitable for the production of bioplastics that are biobased and biodegradable in nature. Use of biopolymers is not limited to bioplastics but ranges from sustainable production of other products such as bio-implants, biofuels, and medicinal products. In this review, we have discussed comprehensively about the sources of biopolymers, their extraction and purification methods and the reasons that make them efficient biopolymers for the environment.

来自生物聚合物的生物塑料:塑料污染的环保和可持续解决方案

摘要

塑料等合成聚合物的全球产量接近 3.9 亿吨/年,这在包括环境、可持续发展和健康在内的许多前沿领域带来了巨大挑战。尽管塑料和石化聚合物是一个在全球经济中占有数十亿美元份额的行业,但其不可降解性是一场巨大的环境危机。每年有 700 万吨陆上塑料垃圾进入海洋和水体,危及海洋生物,这不仅是对水生环境的关注,也是对海产品行业的关注,这表明合成塑料和相关产品造成的水污染。并最终影响人类健康。来自许多生物体的环保和可持续聚合物可用作合成聚合物的替代品。生物聚合物如淀粉、纤维素、果胶、角蛋白、几丁质、明胶和聚羟基链烷酸酯可以从天然生物质来源中获得。所有这些生物聚合物都表现出合适的理化、热和机械性能,使其适用于生产生物基和可生物降解的生物塑料。生物聚合物的使用不仅限于生物塑料,还包括其他产品的可持续生产,如生物植入物、生物燃料和医药产品。在这篇综述中,我们全面讨论了生物聚合物的来源、它们的提取和纯化方法以及使它们成为有效的环境生物聚合物的原因。所有这些生物聚合物都表现出合适的理化、热和机械性能,使其适用于生产生物基和可生物降解的生物塑料。生物聚合物的使用不仅限于生物塑料,还包括其他产品的可持续生产,如生物植入物、生物燃料和医药产品。在这篇综述中,我们全面讨论了生物聚合物的来源、它们的提取和纯化方法以及使它们成为有效的环境生物聚合物的原因。所有这些生物聚合物都表现出合适的理化、热和机械性能,使其适用于生产生物基和可生物降解的生物塑料。生物聚合物的使用不仅限于生物塑料,还包括其他产品的可持续生产,如生物植入物、生物燃料和医药产品。在这篇综述中,我们全面讨论了生物聚合物的来源、它们的提取和纯化方法以及使它们成为有效的环境生物聚合物的原因。和医药产品。在这篇综述中,我们全面讨论了生物聚合物的来源、它们的提取和纯化方法以及使它们成为有效的环境生物聚合物的原因。和医药产品。在这篇综述中,我们全面讨论了生物聚合物的来源、它们的提取和纯化方法以及使它们成为有效的环境生物聚合物的原因。
