生物可降解塑料正在成为合成塑料的替代品,并被广泛用于对抗塑料污染。然而,并非所有生物降解塑料都是可降解的,特别是当它不符合其有利条件时,当涉及到水生环境时。因此,这篇综述旨在强调合成和商业化的各种生物降解塑料的类型,并确定这些微生物塑料或残留生物塑料在各种水生环境中降解后的局限性和优势。这篇综述论文重点介绍了生物降解塑料,生物降解塑料在水生环境中的降解,生物降解塑料的应用,聚乳酸(PLA),聚羟基链烷酸酯(PHA),多糖衍生物,聚(氨基酸),聚己内酯(PCL),聚丁二酸丁二醇酯(PBS),聚己二酸对苯二甲酸丁二醇酯(PBA/T),生物降解塑料在水生环境中降解的局限性和优势。文献检索的时间没有限制,因为该领域正在不断研究,并且没有广泛的研究。可商购的生物可降解塑料在淡水和海洋环境中降解时分别具有其自身的优点和局限性。对生物塑料作为合成塑料的替代品的需求日益增长,合成塑料会导致塑料废物污染。因此,深入了解生物降解塑料的生物降解至关重要,特别是在水生环境中。此外,研究微生物塑料在水生环境中的降解和迁移的研究也很少。
Biodegradable plastics are being the substitute for synthetic plastics and widely been used in order to combat plastic pollution. Yet not all biodegradable plastics are degradable especially when it does not meet its favourable conditions, and also when it comes to aquatic environments. Therefore, this review is intended to highlight the types of various biodegradable plastic synthesized and commercialised and identify the
limitations and advantages of these micro-bioplastics or residual bioplastic upon degradation in various aquatic environments. This review paper highlights on biodegradable plastic, degradation of biodegradable plastic in aquatic environments, application of biodegradable plastic, polylactic acid (PLA), Polyhydroxyalkanoates (PHA), Polysaccharide derivatives, Poly (amino acid), polycaprolactone (PCL), polybutylene succinate (PBS), polybutylene adipate terephthalate (PBA/T),
limitations and advantages of biodegradable plastic degradation in aquatic environment. There is no limit on the period for literature search as this field is continuously being studied and there is no wide range of studies. Biodegradable plastic that is commercially available has its own advantages and
limitations respectively upon degradation in both freshwater and marine environments. There is a growing demand for bioplastic as an alternative to synthetic plastic which causes plastic waste pollution. Thus, it is crucial to understand the biodegradation of biodegradable plastic in depth especially in aquatic environments. Moreover, there are also very few studies investigating the degradation and migration of micro-bioplastics in aquatic environments.
