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.
