The global shift toward sustainable energy has spotlighted water hyacinth () as a promising biofuel feedstock due to its rapid growth and lignocellulosic composition. This PRISMA-based systematic review and Covidence software, evaluates studies from 2015 to 2025, to synthesize technological pathways, cost structures, and environmental trade-offs. Water hyacinth biofuels can reduce levelized cost of energy (LCOE) by 25%, increase ethanol yields by 40%, and improve sugar release by 50%. Multi-product biorefineries enhance viability and offset up to 2.5 tons CO/ha/year. Yet, pilot-scale data, policy alignment, and ecological safeguards remain limited. This review identifies five regional implementation frameworks integrating techno-economic, ecological, and social dimensions. Findings highlight opportunities for circular bioeconomy transitions in developing regions and propose scalable models to transform invasive biomass into renewable energy solutions.
全球向可持续能源的转变使凤眼蓝成为一种有前景的生物燃料原料，因其生长迅速且具有木质纤维素成分。本基于PRISMA的系统综述和Covidence软件，评估了2015年至2025年的研究，以综合技术途径、成本结构和环境权衡。凤眼蓝生物燃料可将能源平准化成本（LCOE）降低25%，乙醇产量提高40%，糖释放量提高50%。多产品生物精炼厂可提高可行性并每年抵消高达2.5吨的二氧化碳排放/公顷。然而，中试规模数据、政策一致性和生态保护措施仍然有限。本综述确定了五个整合技术经济、生态和社会维度的区域实施框架。研究结果突出了发展中地区循环生物经济转型的机会，并提出了将入侵生物质转化为可再生能源解决方案的可扩展模式。
