“…The conversion routes of E. crassipes into bioenergy are through a thermochemical process such as pyrolysis 4,5 or gasification 6 and a biochemical process such as anaerobic digestion (AD). 7 While pyrolysis is deemed one of the most suitable and sustainable thermal conversion processes in transforming biomass to bioenergy because of its simple operation and low investment costs, 4 AD has also received attention because of its adaptation to a broad spectrum of feedstocks, nutrient recovery, and net energy output.…”

Water hyacinth is an invasive alien plant with several impacts on the environment, economy and society. The plant’s high degree of proliferation makes its mitigation difficult and sometimes complex. However, existing evidence suggests that water hyacinth is a sustainable substrate for biogas production. Using the pretreatment processes for the optimisation conditions for biogas production from water hyacinth, this study analysed the effects of moisture content (60%, 70% and 75%) on Trichoderma atroviride pretreatment of water hyacinth and the impact of the pretreatment on biogas production. Anaerobic digestion of the water hyacinth process was performed at 35°C for 35 days. The modified Gompertz model was used to analyse and predict the appropriate kinetic variables of the digestion process. Biogas yields from untreated, pretreated-60%, pretreated-70% and pretreated-75% were optimal at 135, 210, 217 and 223.4 mL/g of volatile solids (VS). These results suggest the pretreatment of water hyacinth enhanced the degradability of water hyacinth by breaking down the cell wall structure and facilitating its use by microorganisms. Furthermore, the results also confirmed that the higher the moisture content, the easier the biodegradation rate and, consequently, the higher the biogas yield. The model predicted maximum methane production potential ranging from 91.84 to 201 mL/g VS, and the maximum methane yield rate was within 10.12–15.12 mL/day. The lag phase varied between 2.46 and 6.94 days. The percentage error between experimental and model outcomes for untreated, pretreated-60%, pretreated-70% and pretreated-75% are 17.96%, 16.67%, 14.20% and 4.68%, respectively, while the coefficients of determination of the model varied between 0.905 and 0.975, demonstrating significant reliability on attained factors.

“…2 The valorisation of water hyacinth for bioenergy production is considered promising because of its availability, high biomass yield and does not contend with arable land with food crops. 3 The conversion routes of E. crassipes into bioenergy are through a thermochemical process such as pyrolysis 4,5 or gasification 6 and a biochemical process such as anaerobic digestion (AD). 7 While pyrolysis is deemed one of the most suitable and sustainable thermal conversion processes in transforming biomass to bioenergy because of its simple operation and low investment costs, 4 AD has also received attention because of its adaptation to a broad spectrum of feedstocks, nutrient recovery, and net energy output.…”

This study aims to investigate the impacts of information, communication, and technology (ICT) factors and economic growth on the hydropower output in the European Union (EU) states from 1990 to 2021. Adopting the autoregressive distributed lag, findings from this study revealed that there could be a significant increase in the hydropower industry growth in EU14 emerging economies using ICT factors than in EU13 emerging economies. It was also discovered that economic growth makes more of a significant contribution to hydropower growth in EU13 emerging economies than in EU14 emerging economies. Findings from this study further revealed that there could be a significant decrease in the carbon dioxide emissions among the EU14 emerged economies using hydropower output than in EU13 emerging economies. This points to the fact that hydropower growth in EU region countries could significantly be enhanced by increasing the level of ICT determinants to achieve Energy Union aims by 2030. This will as well be effective in minimizing or reducing the risk effect of climate change and environmental pollution. Using the pooled mean group, mean group, and dynamic fixed effect methods, the projected calculations are observed to be valid and this study recommended that EU nations should intensify the use of ICT in achieving sustainable environmental and societal goals. The sustainability and security of hydropower production could also be enhanced through legislation. Lawmakers should become active in the green ICT aspects.
