The growing demand for sustainable food packaging and the increasing concerns regarding environmental pollution have driven interest in biodegradable materials. This paper presents an in-depth review of the production of Polyhydroxyalkanoates (PHA), a biodegradable polymer, from food waste. PHA-based bioplastics, particularly when derived from low-cost carbon sources such as volatile fatty acids (VFAs) and waste oils, offer a promising solution for reducing plastic waste and enhancing food packaging sustainability. Through optimization of microbial fermentation processes, PHA production can achieve significant efficiency improvements, with yields reaching up to 87 % PHA content under ideal conditions. This review highlights the technical advancements in using PHA for food packaging, emphasizing its biodegradability, biocompatibility, and potential to serve as a biodegradable alternative to petroleum-based plastics. However, challenges such as high production costs, mechanical limitations, and the need for scalability remain barriers to industrial adoption. The future of PHA in food packaging hinges on overcoming these challenges through further research and innovation in production techniques, material properties, and cost reduction strategies, along with necessary legislative support to promote widespread use.
对可持续食品包装的需求不断增长以及对环境污染的日益关注，引发了人们对可生物降解材料的兴趣。本文深入综述了从食物垃圾中生产聚羟基脂肪酸酯（PHA）这种可生物降解聚合物的情况。基于PHA的生物塑料，特别是当它由挥发性脂肪酸（VFAs）和废油等低成本碳源制成时，为减少塑料垃圾和提高食品包装的可持续性提供了一个有前景的解决方案。通过优化微生物发酵过程，PHA生产能够显著提高效率，在理想条件下产量可达87%的PHA含量。本综述强调了将PHA用于食品包装的技术进步，着重指出其生物可降解性、生物相容性以及作为石油基塑料的可生物降解替代品的潜力。然而，高生产成本、机械性能限制以及扩大规模的需求等挑战仍然是其工业应用的障碍。PHA在食品包装领域的未来取决于通过在生产技术、材料性能和成本降低策略方面的进一步研究与创新来克服这些挑战，同时还需要必要的立法支持以促进其广泛应用。
