“…In this study, carbon dioxide and the methane contents of the produced biogas were measured daily throughout the digestion period. The biogas composition from WH in this study consisted of 63.2% CH 4 and 36.7% CO 2 , and the methane production potential was higher than reported by a similar study, 25 which were 58% CH 4 and 42% CO 2 . This methane production increment is due to the selection of a suitable pretreatment approach using urea before the actual test, so it shows pretreatment of this substrate is important to improve methane production potential, and also it was comparable with H 2 SO 4 pretreated water hyacinth reported by ref.…”

“…From the result, the hemicellulose content is 26.89 ± 2.51%, and hemicellulose is associated with cellulose and contributes to the structural component of the biomass, and cellulose content from the result is 25.39 ± 0.73% . Cellulose is the main structural component in the cell wall, which shows that WH has a good potentiality for biogas production, and it is comparable with a similar study reported by ref. 25, in which the hemicellulose content is 30%, and cellulose content is 24%.…”

“…Various mechanical, chemical, and biological control agents are deployed for limiting its growth, however, there is prerequisite to tap the beneficial aspects after its removal from water bodies. Some studies were reported on utilization of WH for biogas production (Jayaweera, Dilhani, Kularatne, & Wijeyekoon, 2007; Rathod et al, 2018), bioethanol (Zhang, Wei, Han, & Weng, 2018) and biomanure application (Polprasert et al, 1994) but only sporadic research was done utilizing WH as a co‐substrate for anaerobic digestion. To the best of authors' knowledge, this novel attempt of co‐digestion of WH with DW has not been reported so far.…”

To overcome the obstacles of treatment of dairy wastewater (DW) under anaerobic mono‐digestion and sustainable disposal of harvested water hyacinth (WH) a novel sequential valorization strategy was adopted to obtain fuel and fertilizer. Initially, DW and WH were subjected for anaerobic co‐digestion to elucidate the synergistic effect of the substrates to improve the process efficiency and increased biomethane production. The results indicated that the co‐digestion mixture (DW: WH‐1:1) has resulted in biomethane yield of 504.38 L/Kg VSfed which is 1.28‐fold and 3.14‐fold higher as compared to the mono‐digestion of WH (431.71 L/Kg VSfed) and DW (160.59 L/Kg VSfed), respectively. Further, the residual digestate was subjected for slow pyrolysis (320 ± 15°C) to obtain bio‐oil and biochar. The obtained bio‐oil shown superior fuel characteristics as compared to direct WH bio‐oil resulting in density, viscosity, and calorific value of 1.21 ± 0.04 g/ml, 1.8 ± 0.05 cSt and 1766.82 ± 11.53 KJ/Kg, respectively. The biochar residue from pyrolysis was amended to the soil to determine its bio‐fertilizing property. The soil properties in terms of bulk density, porosity, organic carbon, and pH were enhanced. Tomato cultivation in biochar amended soil shown comparable vegetative growth to that of digestate and urea thereby advocating the replacement of chemical fertilizers. Practical Application With recent increase in environmental concerns and requirement to meet the prescribed limits for effluent discharge from the industries, especially from food processing for the protection of aquatic bodies, there is a requirement of adoption of cost effective technology that could provide both economic and ecological sustainability. In this study, a sequential valorization strategy was adopted for efficient management of dairy wastewater and harvested water hyacinth from the water resources. The resultant products biogas, bio‐oil and biochar could be potentially used as fuel and fertilizer. Circular bio‐economy is in need of time which could be attainable by the implementation of such strategies in large scale industries for efficient waste management and resource recovery. This will not only benefit the environment but also to the society by galvanizing the sustainable development technology.

“…The content contained in this biogas is 58% CH4 and 45% CO2. The biogas produced is used as fuel for cooking, lighting, and as a water heater [8]. In addition, because it has a beautiful flower shape, water hyacinth is also considered to have a beautiful artistic or aesthetic value for the environment.…”

The existence of Eichornia crassipes plants is often regarded as a weed that can damage the aquatic environment. However, at this time, Eichornia crassipes can be made into handicraft materials and briquettes. This paper wants to reveal the physical concepts that exist in the process of making handicrafts and briquettes made from Eichornia crassipes. This research is a field study using observation, interviews and reinforced with literature studies. The results showed several physical concepts that can be revealed in making handicrafts and briquettes made from Eichornia crassipes, such as temperature, heat radiation, mechanical advantage. The process of making handicrafts and briquettes from Eichornia crassipes can be used as a source of contextual physics learning during the covid-19 pandemic.
