In search of poly-3-hydroxybutyrate (PHB): A comprehensive review unveiling applications and progress in fostering a sustainable bio-circular economy
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.
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.
