CARRENO-SAYAGO, Uriel F. e RODRIGUEZ-PARRA, Camila. Eichhornia crassipes (Mart.) Solms: an integrated phytoremediation and bioenergy system. Rev. Chapingo ser. cienc. for. ambient [online]. 2019, vol.25, n.3, pp.399-411. Epub 19-Fev-2021. ISSN 2007-4018. https://doi.org/10.5154/r.rchscfa.2018.06.051.
Introduction:
Eichhornia crassipes (Mart.) Solms is an aquatic plant that reproduces rapidly in polluted water. Due to the high adsorption capacity of heavy metals, the plant is used as a phytoremediation agent; its biomass can also be used biofuel production.
Objective:
To compile information on state-of-the-art water treatment processes and biofuel production with E. crassipes to design an integrated biohydrogen and bioethanol production process with the plant’s biomass.
Materials and methods:
The available literature on E. crassipes was reviewed to analyze the designs and propose an integrated phytoremediation and bioenergy system.
Results and discussion:
The proposed design can be adjusted to industrial scale conditions. This design includes a phytoremediation system, a bioreactor to generate hydrolysis, a bioreactor to generate bioethanol and, finally, a bioreactor to generate hydrogen.
Conclusions:
By consulting the state of the art of the proposed designs, it is possible to create and construct, on a large scale, a system for producing bioethanol and biohydrogen from E. crassipes biomass (loaded or not with heavy metals). In this way, the plant biomass is not wasted as it is today.
