“…Due to the lignocellulosic nature of biomasses, the main constituents were probably alkenes, esters, aromatics, alcohols, and ketones with different oxygen-containing functional groups. 21 The elemental analyses indicated high carbon and oxygen contents, 22 and the calculated calorific values were close to the value reported in the literature for water hyacinth (14.36 MJ kg -1 ).…”

“…24 Lignin, which is more stable due to its aromatic structure, decomposes at higher temperatures. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][24][25][26] The decomposition that occurred at 400-600 °C could therefore be attributed to lignin degradation. 12 However, it has been reported that the decomposition of lignin takes place gradually, at a very low rate and throughout the temperature range.…”

The invasive aquatic plants Eichhornia crassipes (water hyacinth), Eichhornia azurea, and Nymphaea spp. were evaluated as sources of lignocellulosic biomass for the production of bio-oil. These plants have high growth rates that can lead to various environmental problems and the production of large amounts of waste biomass. The materials were characterized in terms of their contents of moisture, oil, and ash, and by analysis using thermogravimetry, infrared spectroscopy (IR), elemental analysis, and energy dispersive X-ray fluorescence spectrometry (EDX). The in natura biomasses had moisture contents of around 90%. Micropyrolysis studies were performed at 500 °C using the dried biomasses (ca. 8% moisture). The liquid product of pyrolysis (bio-oil) was trapped in an adsorbent and then eluted with different solvents. The best recovery was achieved using tetrahydrofuran. The bio-oil solutions were derivatized with N-methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA) and analyzed by gas chromatography mass spectrometry (GC-MS). The main compounds found in the bio-oils were glycerol, o-benzenediol, p-benzenediol, arabinoic acid, levuglucosan, and hexadecanoic acid.

“…Water hyacinth was used as a raw material for cultivating straw mushrooms, and the dosage was preferably 20-60% [45]. Singh et al [46] conducted hydrothermal liquefaction of water hyacinth under various conditions. Biswas et al [47] conducted pyrolysis of azolla, verbena, and hyacinth under a nitrogen atmosphere at a temperature of 300-450 • C. The maximum liquid product yield of water hyacinth was 24.6 wt% at 400 • C.…”

Abstract:The unchecked growth of Eichhornia crassipes can cause significant harm, including covering of the water surface, depletion of oxygen, clogging of river channels, and promotion of the breeding of flies and mosquitoes. These effects can significantly impact farmland irrigation, water transportation, and human health. However, methods for controlling its growth are not ideal, and control using biological and chemical agents can result in secondary pollution. The utilization of E. crassipes as a resource, for example, as animal feed or organic substrates, can not only turn waste into valuable resources, but it can also solve the problem of its growth, thus bringing about economic and ecological benefits. In this paper, the growth and ecological characteristics of E. crassipes, its nutrient composition, and resource utilization approaches were reviewed. The challenges associated with the large-scale utilization of E. crassipes were also analyzed in order to provide references for the control and resource utilization of the species. Regarding challenges such as the difficulty of cultivation and the high cost of harvesting and dehydrating, it is necessary to investigate the proper water surface and coverage characteristics of E. crassipes cultivation to assure adequate biomass and protect the ecological landscape. It is also necessary to evaluate the effect of E. crassipes cultivation on the health of aquatic ecosystems and the safety of the water environment in order to prevent the significant potential ecological and environmental risks. In addition, developing portable, high-efficiency facilities to promote the effectiveness of harvesting, transportation and dehydration are needed, as well as further improvement in the techniques of utilization and assessment of the economic value.
