The aim to achieve sustainable development goals (SDG) and cut CO-emission is forcing researchers to develop bio-based materials over conventional polymers. Since most of the established bio-based polymeric materials demonstrate prominent sustainability, however, performance, cost, and durability limit their utilization in real-time applications. Additionally, a sustainable circular bioeconomy (CE) ensures SDGs deliver material production, where it ceases the linear approach from production to waste. Simultaneously, sustainable circular bio-economy promoted materials should exhibit the prominent properties to involve and substitute conventional materials. These interceptions can be resolved through state-of-the-art bio-vitrimeric materials that display durability/mechanical properties such as thermosets and processability/malleability such as thermoplastics. This article emphasizes the current need for vitrimers based on bio-derived chemicals; as well as to summarize the developed bio-based vitrimers (including reprocessing, recycling and self-healing properties) and their requirements for a sustainable circular economy in future prospects.
实现可持续发展目标（SDG）和减少碳排放的目标促使研究人员开发基于生物的材料，而非传统聚合物。然而，由于大多数已有的基于生物的聚合材料虽展现出显著的可持续性，但性能、成本和耐久性限制了它们在实时应用中的使用。此外，可持续循环生物经济（CE）确保可持续发展目标实现物质生产，它摒弃了从生产到废弃物的线性模式。同时，可持续循环生物经济推动的材料应具备突出性能，以纳入并替代传统材料。这些问题可通过先进的生物玻璃态材料解决，这类材料兼具热固性材料的耐久性/机械性能以及热塑性材料的可加工性/延展性。本文强调了当前对基于生物衍生化学品的玻璃态材料的需求；并总结了已开发的基于生物的玻璃态材料（包括再加工、回收和自愈性能）及其在未来前景中对可持续循环经济的要求。
