Abstract Polyhydroxyalkanoates (PHAs) belong to group of biopolymers that have in recent times received growing research interest as a result of being eco-friendly and close characteristics with petrochemical based plastics. Alternatives to utilization of synthetic plastics are being explored since synthetic plastics are non-recyclable and non-biodegradable in nature. One of the innovations of Green Chemistry is utilization of renewable feedstocks such as biomass to achieve sustainable development with future circular economy. Bio-based products are of great interest to sustainable development as a result of diminishing fossil fuel reserves and rising environmental concerns. This review summarizes the productions of PHAs from renewable feedstocks such as lignocellulose, crude glycerol, levulinic acid (LA), palm-oil mill effluents (POME) and waste oils. The production of bio-based polymers has become much more professional and differentiated in recent years. Presently, there are bio-based alternatives for practically every application, therefore, this review presents applications of PHA in bio-refinery, medical sectors, agriculture sector, construction industry, and in packaging industry. The cost analysis of PHA from renewable sources with commercially available ones and potential to attain circular economy were also stressed. The reasons for this shift are connected to the non-renewability of fossil-based resources, the deteriorating environmental impacts, and the lack of biodegradability of the petroleum-produced materials.

生物质中聚羟基链烷酸酯(PHA)的可持续合成与应用

摘要 聚羟基链烷酸酯 (PHA) 属于一类生物聚合物,由于具有环保和与石化塑料相似的特性,近年来受到越来越多的研究兴趣。由于合成塑料本质上是不可回收和不可生物降解的,因此正在探索使用合成塑料的替代方法。绿色化学的创新之一是利用生物质等可再生原料实现未来循环经济的可持续发展。由于化石燃料储量减少和环境问题日益严重,生物基产品对可持续发展具有重要意义。本综述总结了从可再生原料如木质纤维素、粗甘油、乙酰丙酸 (LA)、棕榈油厂废水 (POME) 和废油。近年来,生物基聚合物的生产变得更加专业和差异化。目前,几乎所有应用都有基于生物的替代品,因此,本综述介绍了 PHA 在生物炼油厂、医疗部门、农业部门、建筑业和包装业中的应用。还强调了对来自可再生能源的 PHA 的成本分析以及商业上可获得的和实现循环经济的潜力。这种转变的原因与化石资源的不可再生性、不断恶化的环境影响以及石油生产材料缺乏生物降解性有关。几乎所有应用都有基于生物的替代品,因此,本综述介绍了 PHA 在生物精炼、医疗部门、农业部门、建筑业和包装行业中的应用。还强调了对来自可再生能源的 PHA 的成本分析以及商业上可获得的和实现循环经济的潜力。这种转变的原因与化石资源的不可再生性、不断恶化的环境影响以及石油生产材料缺乏生物降解性有关。几乎所有应用都有基于生物的替代品,因此,本综述介绍了 PHA 在生物精炼、医疗部门、农业部门、建筑业和包装行业中的应用。还强调了对来自可再生能源的 PHA 的成本分析以及商业上可获得的和实现循环经济的潜力。这种转变的原因与化石资源的不可再生性、不断恶化的环境影响以及石油生产材料缺乏生物降解性有关。还强调了对来自可再生能源的 PHA 的成本分析以及商业上可获得的和实现循环经济的潜力。这种转变的原因与化石资源的不可再生性、不断恶化的环境影响以及石油生产材料缺乏生物降解性有关。还强调了对来自可再生能源的 PHA 的成本分析以及商业上可获得的和实现循环经济的潜力。这种转变的原因与化石资源的不可再生性、不断恶化的环境影响以及石油生产材料缺乏生物降解性有关。
