Colombia's continuous contamination of water resources and the low alternatives to produce biofuels have affected the fulfillment of the objectives of sustainable development, deteriorating the environment and affecting the economic productivity of this country. Due to this reality, projects on environmental and economic sustainability, phytoremediation, and the production of biofuels such as ethanol and hydrogen were combined. The objective of this article was to design and develop a sustainable system for wastewater treatment and the generation of biofuels based on the biomass of the aquatic plant Eichhornia crassipes. A system that simulates an artificial wetland with live E. crassipes plants was designed and developed, removing organic matter contaminants; subsequently, and continuing the sustainability project, bioreactors were designed, adapted, and started up to produce bioethanol and biohydrogen with the hydrolyzed biomass used in the phytoremediation process, generating around 12 g/L of bioethanol and around 81 ml H/g. The proposed research strategy suggests combining two sustainable methods, bioremediation and biofuel production, to preserve the natural beauty of water systems and their surroundings.
哥伦比亚持续的水资源污染和生产生物燃料的低替代方案，影响了可持续发展目标的实现，恶化了环境，影响了这个国家的经济生产力。鉴于这一现实，开展了环境和经济可持续性、植物修复以及生产乙醇和氢气等生物燃料的项目。本文的目的是设计和开发一种基于水生植物凤眼蓝生物质的废水处理和生物燃料生产的可持续系统。设计和开发了一个模拟带有活体凤眼蓝植物的人工湿地系统，以去除有机污染物；随后，为了继续可持续发展项目，设计、改造并启动了生物反应器，利用在植物修复过程中使用的水解生物质生产生物乙醇和生物氢气，产生约 12 g/L 的生物乙醇和约 81 ml H/g。所提出的研究策略建议将两种可持续方法（生物修复和生物燃料生产）结合起来，以保护水系统及其周围环境的自然之美。
