通过制造增值产品来实现食物垃圾的价值，在世界许多地方已经研究了近十年。尽管最近的研究很流行，但越来越多的食物浪费仍然是一个问题。将厨余转化为有用的产品可用于应对2019冠状病毒病（COVID-19）大流行。目前从废弃食物中提取营养素并促进其被微生物利用的方法产生了各种平台化学品和燃料，例如琥珀酸、乳酸、乙醇和氢，以及聚合物，例如均聚物聚羟基丁酸酯（PHB）、共聚物聚（3-羟基丁酸酯-共-3-羟基戊酸酯）（PHBV）和聚乳酸（PLA）。本章全面回顾了有关基于食物垃圾的生物聚合物生产及其在抗击COVID-19大流行中的可能应用的科学文章和报告。用于生产生物聚合物或其构建块的关键微生物是Haloferax medicinei，Cupravidus necator和Lactobacillus caseiShirota。从这些微生物衍生的生物聚合物和组分可用于生产绿色、可生物降解的非织造织物。这些生物聚合物的灵活性和生物降解性也使其适用于医疗领域的应用。通过静电纺丝工艺，此类织物可用于生产可生物降解的个人防护设备（PPE），从而可持续地对抗COVID-19。实施食物垃圾价值评估不仅有助于管理废物和减少环境污染，还有助于产生资源，如医用纺织品，可以大规模满足长期可持续发展目标。
Food waste valorisation through the manufacture of value-added products has been studied for nearly a decade in many parts of the world. Despite the prevalence of recent studies, increasing food waste remains a problem. The transformation of food waste into useful products could be harnessed to tackle the coronavirus disease 2019 (COVID-19) pandemic. The current method of extracting nutrients from wasted food and facilitating their utilisation by microbes generates various platform chemicals and fuels, such as succinic acid, lactic acid, ethanol and hydrogen, and polymers, such as homopolymer polyhydroxybutyrate (PHB), copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and polylactic acid (PLA). A thorough review of scientific articles and reports on food waste-based biopolymer production and its possible applications in combating the COVID-19 pandemic is presented in this chapter. The key microbes used to produce either biopolymers or their building blocks areHaloferax mediterranei,Cupravidus necator,and Lactobacillus caseiShirota. The biopolymers and components derived from these microbes can be used to produce green, biodegradable, non-woven fabrics. The flexibility and biodegradability of these biopolymers also make them suitable for applications in the medical sector. Through the process of electrospinning, such fabrics can be used to produce biodegradable personal protective equipment (PPE) and, thereby, combat COVID-19 sustainably. The implementation of food waste valorisation helps not only in managing waste and reducing environmental pollution but also in generating resources, such as medical textiles, that can meet long-term sustainable development goals on a large scale.
