The accumulation of conventional petroleum-based polymers has increased exponentially over the years. Therefore, algae-based biopolymer has gained interest among researchers as one of the alternative approaches in achieving a sustainable circular economy around the world. The benefits of microalgae biopolymer over other feedstock is its autotrophic complex to reduce the greenhouse gases emission, rapid growing ability with flexibility in diverse environments and its ability to compost that gives greenhouse gas credits. In contrast, this review provides a comprehensive understanding of algae-based biopolymer in the evaluation of microalgae strains, bioplastic characterization and bioplastic blending technologies. The future prospects and challenges on the algae circular bioeconomy which includes the challenges faced in circular economy, issues regard to the scale-up and operating cost of microalgae cultivation and the life cycle assessment on algal-based biopolymer were highlighted. The aim of this review is to provide insights of algae-based biopolymer towards a sustainable circular bioeconomy.
多年来，传统基于石油的聚合物的积累呈指数级增长。因此，藻类生物聚合物作为在全球范围内实现可持续循环经济的替代方法之一，引起了研究人员的兴趣。与其他原料相比，微藻生物聚合物的优势在于其自养特性，可减少温室气体排放，具有在不同环境中快速生长的能力和可堆肥性，可获得温室气体信用。相比之下，本综述提供了对藻类生物聚合物的全面了解，包括对微藻菌株的评价、生物塑料特性和生物塑料共混技术。藻类循环生物经济的未来前景和挑战也得到了强调，其中包括循环经济面临的挑战、微藻培养的规模化和运营成本问题以及基于藻类的生物聚合物的生命周期评估。本综述的目的是提供对藻类生物聚合物在可持续循环生物经济中的见解。
