Water hyacinth management is of utmost importance. If the weed is not properly managed, aquatic life could suffer. There may not be a single, generally acceptable way of controlling the weed as the peculiarity of its invasiveness in different environments may be different. Getting rid of the weed completely may be difficult to achieve due to its ability to grow fast and spread within a short period of time; however, the sole objective of any control measure should be to eliminate the plant faster than it grows. Awareness and community mobilization on the need to ensure that the growth of the weed does not become a menace should be engaged in regularly. Nongovernmental Organizations (NGOs) on issues relating to the environment should also actively participate in the campaign to effectively manage the growth of the weed. Government agencies and ministries should also take the lead in battling the scourge of the invasiveness of the weed. According to Degega [ 9], the best control strategy is by preventing its growth in water bodies. The long-term effects of individual control techniques, with continued utilization, should help mitigate the negative impacts of this plant [ 111]. To achieve more efficiency, a combination of control strategies may be employed. There are three major ways by which water hyacinth is being controlled: mechanical/manual, chemical, and biological control. 1.19. Mechanical/Manual Removal The process of using earthworms to transform organic biomass into nutrient-rich compost that mainly comprises earthworms with a mixture of decomposed organic matter is called vermicomposting. The resulting compost functions as a eutrophic natural manure and soil stimulant [ 48]. Vermicompost is obtained when organic waste decomposed by microbes in the digestive tracts of earthworms [ 49]. Water hyacinth has been found to be a very good vermicomposting raw material. In combination with cow dung, water hyacinth was successfully converted into vermicompost in Zimbabwe [ 50] but, in fact, was found to yield better vermicompost when used alone as a substrate for earthworms [ 49]. Vermicomposting E. crassipes from Lake Victoria in Kenya yielded richer vermicompost [ 51]. Vermicomposting using water hyacinth mixed with cow dung significantly improved the growth of Arachis hypogaea planted in the field [ 52]. Water hyacinth vermicomposted with Lactobacillus sporogenes led to an increase in nutrient composition of the vermicompost after 60 days, suggesting that the weed could be a good biofertilizer [ 53]. 1.7.

Pole-type varieties of hyacinth beans need trellises to support their growth, while bush-type varieties do not need trellises to stay upright. Most hyacinth beans have purplish stems and white to purple flowers, and their pods have purple margins.

However, higher starch content is attained when harvested at eleven to twelve months. Like most root crops, arrowroot is harvested by passing the plow along the furrow to expose the roots.

The microbial carriers were collected from the reactor on day 49 of the experiment and washed with a phosphate buffer solution (pH = 7.2) to remove excess sludge. Afterward, the carriers were fixed overnight in a 2.5% (v/v) glutaraldehyde solution [ 20]. The samples for SEM were prepared based on freeze-drying [ 21]. The SEM samples were washed with pure water, dried using a freeze dryer (FD-6510, SUN Technologies), and coated with osmium using a metal coating device (HPC-1S, Vacuum Device). The micrographs of these samples were taken using a SEM (JSM-7500F, JEOL). Microbial Community Analysis Eichhornia crassipes is an invasive weed found in several aquatic ecosystems all over the world: lotic, lentic waters, creeks, and creeklets [ 30]. The intense rate of proliferation of E. crassipes results in a change in the chemistry of water and disruption of aquatic biota, thereby rapidly increasing water loss due to evapotranspiration. The threat the weed has posed to biodiversity has been described as alarming and lately, attention is being given to using it for numerous other purposes [ 35]. The weed can impact the health of aquatic ecosystems and the safety of the water environment thereby causing significant potential ecological and environmental risks [ 21]. Nevertheless, the plant can be exploited for a variety of beneficial uses. The plants’ biomass is useful for bioremediation and bioaccumulation of hazardous pollutants and metals; for production of biogas and biofuel; as a source of feed for fishes and animals; as a carbon source for microbial metabolism, in vermicomposting and compost production; and in medical and several other essential aspects [ 2]. The economic importance (positive and negative) of water hyacinth across several regions is discussed hereinafter. 1.5. Bioremediation (Phytoremediation) The ThrillionX Team won in the Circular Economy and Social Innovation category for "The Water Hyacinth Kitchen Sponge", with 4 high school students from Mater Dei School in Bangkok, Thailand (all female). This project aims to solve the problem of hyacinth in the canal by proposing the idea of using the cellulose content in water hyacinth to make a sponge, instead of polyester, which is made of plastic. The water hyacinth fibre can reduce the waste of plastic sponges, protect the environment, and enhance the livelihood of local Thai people.
