This study aims to present a systematic data-driven bibliometric analysis of the water hyacinth (Eichhornia crassipes) infestation problem around the globe. As many solutions are being proposed in academia for its management, mitigation, and utilization, it requires investigation through a systematic scrutinizing lens. In this study, literature records from 1977 to June 2020 concerning research on water hyacinth are taken from Scopus for text analysis. Trends in the publication of different article types, dynamics of publication, clustering, correlation, and co-authoring patterns between different countries are observed. The cluster analysis indicated four clusters viz. (i) ecological works related to species, (ii) pollutant removal process and methods, (iii) utilization of biofuels for biogas production, and (iv) modelling works. It is clear from the networking analysis that most of the publications regarding water hyacinth are from India, followed by China and the United States. Sentiment analysis with the AFINN lexicon showed that the negative sentiment towards the aquatic weed has intensified over time. An exploratory analysis was performed using a bigram network plot, depicting and outlining different important domains of water hyacinth research. Water hyacinth research has passed the pioneering phase and is now at the end of a steady growth phase or at the beginning of an acceleration phase. In this article, an overview is given for the entirety of water hyacinth research, with an indication of future trends and possibilities.

Water hyacinth is the world's worst water weed that is responsible for many environmental and economical problems. Nigerian fresh waters have been infested with this aquatic weed. In this work, a Natural Convection Mixed Mode Solar Dryer for drying water hyacinth to about 10% of its moisture content was constructed and tested as a component of controlling its infestation of the River Benue. The performance of the dryer was compared with the traditional open–air sun drying as the control for drying water hyacinth in Makurdi, Benue State Nigeria. The water hyacinth was dried for 8 hours each day for 4 days. 500g of water hyacinth on wet basis was dehydrated by about 437g on dry basis in 20 hours in the dryer while the control required 32 hours. The dryer was found to be technically more suitable for drying water hyacinth both in terms of the drying rate and quality of the dried product.

Water Hyacinth (Eichhornia crassipes) is a dangerous and invasive aquatic species, of which global concern has sharply risen due to its rapid growth. Despite ample research on its possible applications in the construction field, there are no clear references on the optimal use of the plant in finding the most efficient-use building material. In this paper, a microstructural and chemical characterization of the Water Hyacinth petiole was performed, in order to find the most efficient use as a construction material. Subsequently, two types of binder-less insulation panels were developed, with two types of particle size (pulp and staple). A physical, mechanical, and thermal characterization of the boards was performed. These results demonstrated that it is possible to manufacture self-supporting Water Hyacinth petiole panels without an artificial polymer matrix for thermal insulation. The boards showed good thermal conductivity values, ranging from 0.047–0.065 W/mK. In addition, clear differences were found in the properties of the boards, depending on the type of Water Hyacinth petiole particle size, due to the differences in the microstructure.

Abstract Eichhornia crassipes (Water hyacinth) is considered as a hazardous weed in numerous places of the world. Despite of its harmful effects, the weed offers potential substrate for production of monetarily industrial important and value added products. In the present study, an eco-friendly bioconversion or biotransformation of processed water hyacinth biomass (WHB) into high efficiency fuel, adsorbent for brewery industry waste water treatment coupled methylene blue dye, biofertilizer and nutrient media for viable inoculam production of fungal biopesticide Nomuraea rileyi was carried out adopting green science in situ principles. Bioconversion of the WHB was initiated by alkali treatment which brought about notable differences in physical texture and chemical composition. Pre-treated WHB was enzymatically hydrolysed into soluble simple sugars followed by fermentation of the sugar into ethanol with 65.2 % total yield with 77.3 g/l final concentration. Batch studies reveals that WHB brought about effective reduction of various physicio chemical properties and notable adsorption efficacy. Plant growth promoting effect was studied using green gram (Vigna mungo). Green gram grew on soil under pot culture technique inoculated with WHB uncovers imperative plant growth promotion effect. Culture medium prepared from reconstituted WHB supported viable inoculum production of potential fungal biopesticide Beauveria bassiana. Fungal inoculum derived from the WHB based culture medium was effective against larval instars of castor semi-looper Achaea janata in terms of high mortality.The present examination uncovers the conceivable viable bioconversion of water hyacinth biomass (WHB) into different worth included vitality, ecological as gives a green procedure to cleaner production and the executives of aquatic invasive weeds.

An experiment was conducted during 2016-2017 to assess the efficacy of co-composting technique for generating quality manure out of the noxious aquatic weed, water hyacinth (Eichhornia crassipes). Locally available organic substrates viz., crop residues and cow dung were mixed with water hyacinth and co-inoculated with the fungal culture, Pleurotus djamor @ 0.05% and the earth worm, Eudrillus eugineae @ 0.2%. The treatment encompassing water hyacinth + crop residue + cow dung (1:1:1) along with P. djamor and E.eugineae showed higher mean values of total “N” (0.93%), “P” (1.00%), “K” (1.10%) content of manure, germination percentage (100 % each) and vigour index of 13.90 and 12.85, respectively for cluster bean and tomato ; whereas, water hyacinth + crop residues (1:1) without the bio-inoculants recorded higher mean total organic carbon of 40.85 %.
