“…In addition to rising demand for the constructions of more irrigation and drainage canals that infested with aquatic weeds of water hyacinth under improper maintenance. The disposal of these aquatic weed has become an increasing problem and a growing expense for the country, farmers and agricultural authorities, especially in the light of further water scarcity and climate change (Allam et al, 2020;Gaurav et al, 2020). Organic biomass in general are valuable resources when properly managed and applied to soils, both as a fertilizer and as a soil amendment.…”

Soil application of water hyacinth biochar as a source of nutrient-and carbon-rich biomass may be an effective ploy to eradicate this invasive aquatic weed. Incubation trial was conducted to assess effects of water hyacinth biochar addition on some sandy soil biochemical and biological properties and potential carbon sequestration at different application rates and methods. Results demonstrated that pyrolysis of water hyacinth at temperature of 300 °C and 30 min furnace residence time produced biochar with coveted physicochemical properties. Field emission scanning electronic microscopy (FE-SEM) images obtained for water hyacinth biochar showed major macroscopic changes caused by substantial changes in pore structure, surface area and surface morphology due to insufficient carbonization. Soil biochemical and microbiological characteristics after incubation exposed obvious significant improvements at all rates compared to control and varied markedly between addition of biochar as incorporation and broadcasting. Among different treatments, biochar addition as incorporation at the rate of 3% resulted in higher significant increases in most tested soil parameters. Water hyacinth biochar provided nitrogen and carbon immediately via SOC, DOC and DON in treated sandy soils providing energy for microbial biomass compared to control and this reflected by increases in soil values of C-MIC N-MIC and P-MIC. In addition, water hyacinth biocharring would greatly improve sandy soil carbon sequestration at high application rates. It could be concluded that water hyacinth transformation into biochar represents a sustainable strategy for managing these weeds and thus become a valuable organic source for sandy soils and will boost carbon sequestration.

“…Conversely, a remarkable number of studies have emerged for the potential use and conversion of water hyacinth into value-added products, suggesting a positive aspect of the weed [ 12 , 13 , 14 , 15 , 16 ]. Transforming management issues into opportunities and harvesting water hyacinth through physical and mechanical means by collecting its biomass can be manageable, feasible, and profitable.…”

“…Current and recent reviews addressing the valorisation of water hyacinth have focused on several aspects, including water hyacinth biomass-to-energy [ 15 ], biochar production potential [ 12 ], phytoremediation capacities [ 17 ], cost-benefit analyses and the economic feasibility of its utilisation [ 12 , 13 , 18 ] and various other products [ 16 ]. Though frequently mentioned in previous works of literature, the direct and indirect prospects for the utilisation of water hyacinth in affected, and especially rural areas, for the benefit of the people within those areas, has not yet been thoroughly discussed.…”

Water hyacinth (WH) is notorious for causing severe environmental degradation and being an economic burden to manage. However, it offers substantial prospects if exploited, especially by rural communities. High temperatures, eutrophic conditions and other environmental factors promote the proliferation of the plant in regions where it has been introduced. Regarded as among the world’s worst invasive weeds, WH is nearly impossible to control and eradicate without an integrated approach and community participation. The effectiveness of control methods varies, yet sustained community involvement determines the long-term success of these methods. Reproducing rapidly, WH has the resource capacity to support a unique microeconomic ecosystem, incentivising WH control by generating sustainable income. The WH ecology, the socioeconomic impacts of its invasion and its various applications are reviewed, and revenue generation and cost-saving options are highlighted. A circular microeconomic model is proposed by integrating WH valorisation into the general limitations of a rural community. Empowering locals with opportunities and enticing them with potential economic gains can be a nudge towards a pro-environment behavioural change in managing WH. This would aid in upgrading local livelihoods and could foster resilience within the community in tackling both environmental problems and economic setbacks through the management of WH invasions.

“…In general, the types of plants commonly used in PMFCs to produce more electricity are those that live in water due to their electrolyte capability (Wetser et al, 2016). Some types of plants commonly used are Spartina anglica, Phragmites australis, and Eichhornia crassipes (Timmers et al, 2010;Wetser et al, 2015;Di et al, 2020;Zhou et al, 2018;Gaurav et al, 2020). Eichhornia crassipes or water hyacinth is commonly used due to its numerous advantages, such as being readily obtained, easily cultivated, ability to grow in water and wetlands, thereby making it useable for bioremediation (Pamintuan et al, 2018).…”

The plant microbial fuel cell (PMFC) is a technology built to produce renewable and sustainable electricityin order to meet the increasing global demand. This study demonstrates the potential application of PMFC in swamps dominated by water hyacinth to produce biological energy and plant biomass.In this research, the plant was integrated into a microbial fuel cell that adopts various types of anode materials such as carbon felt, iron and zinc, with a varying distance of 10 and 20 cm between the anode and cathode. Organic compounds emerging from the photosynthesis process were deposited by plant roots, which were then oxidized by bacteria in the mud media. The result showed that the developed PMFC produced a voltage and current density of 244.8 mV and 185.4 mA/m2, respectively, for 30 days, with a maximum power of 100.2 mW/m2 in the cells using zinc as anode material with an electrode spacing of 10 cm. Furthermore, the pH value on PMFC with a longer electrode was higher than the shorter distance due to the protons' inability to move from anode to cathode against the force of gravity. In conclusion, PMFC which utilizes water hyacinth has a good performance in converting chemical energy from the substrate into electrical energy, and has the potential to be developed in underdeveloped areas.
