Abstract

The escalating demand for economical and durable materials has propelled plastics into an indispensable facet of daily human life, dominating commercial and industrial sectors. The global plastic production of 1.1 billion tons by 2050 exacerbates concerns. The COVID-19 pandemic has further intensified the issue, reaching an alarming 0.3–0.4 billion tons annually. Urgent action is imperative to curtail the drastic environmental impact. Various strategies, particularly microbial involvement in plastic production and degradation, must be implemented to address this. Poly-3-Hydroxybutyrate (PHB) microbial polyesters present a promising alternative to conventional plastics because of their biodegradable nature, thus offering a sustainable solution to plastic pollution. PHBs are employed in divergent industries, including agriculture, medicine, nanotechnology, food, and tissue engineering. This comprehensive review addresses the gap in the literature by encompassing a wide range of topics related to PHBs, their associated enzymes, metabolic pathways, and applications. It also provides an in-depth analysis, highlighting the significance of diverse microbial communities in both the synthesis and degradation of biopolymers. Strategies for augmenting PHA production and leveraging waste products for circular economy initiatives are also discussed, emphasizing the need for innovative solutions to address the global plastic crisis.Top of Form This review highlights two critical strategies for tackling plastic pollution: introducing alternative materials like bioplastics and leveraging biological recycling with microbial assistance. Adopting bio-based circular economy strategies, implementing comprehensive 6 R waste management practices, strengthening plastic pollution regulations, and raising social awareness can significantly improve eco-friendly plastic waste management, diminish pollution, and enhance socio-economic conditions, thus benefiting economies worldwide.

寻找聚 3-羟基丁酸（PHB）：全面回顾在促进可持续生物循环经济方面的应用和进展

人们对经济耐用材料的需求不断增长，塑料已成为人类日常生活中不可或缺的一部分，在商业和工业领域占据主导地位。到 2050 年，全球塑料产量将达到 11 亿吨，这加剧了人们的担忧。COVID-19 大流行进一步加剧了这一问题，年产量达到惊人的 3-4 亿吨。当务之急是采取紧急行动，减少对环境的严重影响。为此，必须实施各种策略，特别是微生物参与塑料生产和降解的策略。聚 3-羟基丁酸（PHB）微生物聚酯因其可生物降解的特性，成为替代传统塑料的理想选择，从而为塑料污染提供了一种可持续的解决方案。PHB 可用于多种行业，包括农业、医药、纳米技术、食品和组织工程。本综述涵盖了与 PHBs、其相关酶、代谢途径和应用有关的广泛主题，填补了文献空白。它还进行了深入分析，强调了不同微生物群落在生物聚合物合成和降解过程中的重要作用。本综述强调了解决塑料污染问题的两大关键策略：引入生物塑料等替代材料以及利用微生物辅助生物回收。采用以生物为基础的循环经济战略、实施全面的 6 R 废物管理措施、加强塑料污染法规以及提高社会意识，可以显著改善生态友好型塑料废物管理、减少污染并改善社会经济状况，从而惠及全球经济。

期刊介绍： Official Journal of the European Federation of Chemical Engineering: Part C FBP aims to be the principal international journal for publication of high quality, original papers in the branches of engineering and science dedicated to the safe processing of biological products. It is the only journal to exploit the synergy between biotechnology, bioprocessing and food engineering. Papers showing how research results can be used in engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in equipment or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of food and bioproducts processing. The journal has a strong emphasis on the interface between engineering and food or bioproducts. Papers that are not likely to be published are those: • Primarily concerned with food formulation • That use experimental design techniques to obtain response surfaces but gain little insight from them • That are empirical and ignore established mechanistic models, e.g., empirical drying curves • That are primarily concerned about sensory evaluation and colour • Concern the extraction, encapsulation and/or antioxidant activity of a specific biological material without providing insight that could be applied to a similar but different material, • Containing only chemical analyses of biological materials.
