“…It results in a high degree of treatment, reducing DBO, nitrogen, and phosphorus levels 8 . Also, this same biomass can be transformed into biofuels, such as bioethanol and biohydrogen 9 – 12 . These biotechnologies could help the country in two important areas: water treatment and energy generation.…”

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 H2/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.

“…The residual digestate was used for pyrolysis to obtain bio-oil and biochar. Another study indicated that the biochar obtained from WH pyrolysis could serve for heavy metal adsorption, and could be used for bioremediation application (Hasan et al, 2021). In addition, an integration strategy of hydrothermal carbonization (HTC) and anaerobic digestion (AD) using WH, showed that hydrochars and process waters from HTC process, could be valorized for a solid combustion fuel and biomethane production (Brown et al, 2020).…”

The proliferation of the invasive Water hyacinth (WH) plant leads to ecological, economic, public health, and agricultural problems. Several efforts have been deployed to control its spread, but no concreate results have been obtained. Only few studies dealing with systematic approaches for the WH control have been conducted. To establish a road map for the best control methods to be adopted, this review highlights the control programs that have been tested worldwide and describes, through a deep literature analysis and comparison, the most effective and sustainable control programs for managing the proliferation of this aquatic weed. Through a critical analysis, this review evaluates the advantages and drawbacks of the main proposed control methods including biological, chemical and physical methods. The obtained results suggested that short and medium term physical control promptly manages the plant’s proliferation and thus could complement the effect of the biological control. Moreover, to be economically viable, the harvested WH through physical means must be valorized to generate high value-added products. Furthermore, run-off nutrients control could reduce the end-of-catchment loads and would help the resilience of freshwater bodies and promote plant removal. Descriptive results analysis confirmed that an integrated control approach combining “biological and physical’’ is the most sustainable and cost-effective approach. The adaptation of these methods based on the socio-economic context of each country, could promote ecosystem restoration, self-generation, and conservation for a sustainable development.

“…WH ash has been reported to absorb phenol and heavy metal pollution from water, and the adsorption efficiency is higher at a low pH [ 30 ]. Biochar is another remarkable application form of WH and has shown substantial capacity for remediating a wide range of pollutants, including heavy metals, antibiotics, phenols, dyes, and so on [ 66 , 84 , 85 , 86 ]. Moreover, the WH derived-biochar could be made into composites with other materials to further improve the adsorption efficiency.…”

Water hyacinth (Eichhornia crassipes) (WH) is a widespread aquatic plant. As a top invasive macrophyte, WH causes enormous economic and ecological losses. To control it, various physical, chemical and biological methods have been developed. However, multiple drawbacks of these methods limited their application. While being a noxious macrophyte, WH has great potential in many areas, such as phytoremediation, manufacture of value-added products, and so on. Resource utilization of WH has enormous benefits and therefore, is a sustainable strategy for its control. In accordance with the increasing urgency of maintaining environmental sustainability, this review concisely introduced up to date WH utilization specifically in pollution remediation and curbing the global warming crisis and discussed the underlying mechanisms.
