Production of electricity, heat and fuel are important for today’s social and economic growth. Biogas produced by anaerobic co-digestion is an alternative, carbon-neutral, renewable fuel that can be generated from local, low-cost organic materials. Co-digestion of Water Hyacinth (Eichhornia crassipes) and cow manure, was performed with a designed laboratory anaerobic fermentation system at 39°C ± 2°C. Co-digestion was conducted with 100% cow manure as a basis, and cow manure and water hyacinth ratios of 25%:75%:, 50%:50%, and 25%:75% for complete water hyacinth plants, water hyacinth roots and water hyacinth leaves fractions. Biogas production per gram volatile solid for anaerobic digested cow manure was between 134 ml to 355.59 ml. Co-digestion of cow manure and water hyacinth showed the highest average biogas production per gram volatile solids for complete water hyacinth and water hyacinth root mixture ratios of 25% cow manure and 75% of water hyacinth and water hyacinth roots yielding 273.01 ml and 462.63 ml respectively. The least biogas per gram volatile solids produced during co-fermentation was for complete water hyacinth and water hyacinth root with a ratio of 75% cow manure and 25% water hyacinth and water hyacinth root, yielding 163.77 ml and 250.28 ml respectively. Water hyacinth leave mixture at 50% cow manure and 50% water hyacinth leaves had the lowest average biogas production of 172.54 ml per gram volatile solids. The highest biogas production of 283.55 ml per gram volatile solids was achieved for a mixture of 75% cow manure and 25% water hyacinth leaves. The biogas composition without CO2 showed a biogas content for the cow manure between 54 and 65%. The application of co-digestion utilizing cow manure and water hyacinth as a feedstock could help minimize the negative environmental impact of water hyacinth and help to restore biodiversity, water quality and habitat of infested sites.

Water hyacinth (Eichhornia crassipes) causes ecological and economic problems because it grows very fast and quickly consumes nutrients and oxygen in water bodies, affecting both the flora and fauna; besides, it can form blockages in the waterways, hindering fishing and boat use. However, this plant contains bioactive compounds that can be used to produce biofuels. This study investigated the effect of various substrates as feedstock for biogas production. A 125-l plug-flow anaerobic digester was utilized and the hydraulic retention time was 14 days; cow dung was inoculated into water hyacinth at a 2:1 mass ratio over 7 days. The maximum biogas yield, achieved using a mixture of natural water hyacinth and water (NWH-W), was 0.398 l/g volatile solids (VS). The cow dung/water (CD-W), hydrothermally pretreated water hyacinth/digestate, and hydrothermally pretreated water hyacinth/water (TWH-W) mixtures reached biogas yields of 0.239, 0.2198, and 0.115 l/g VS, respectively. The NWH-W composition was 70.57% CH4, 12.26% CO2, 1.32% H2S, and 0.65% NH3. The modified Gompertz kinetic model provided data satisfactorily compatible with the experimental one to determine the biogas production from various substrates. TWH-W and NWH-W achieved, respectively, the shortest and (6.561 days) and the longest (7.281 days) lag phase, the lowest (0.133 (l/g VS)/day) and the highest (0.446 (l/g VS)/day) biogas production rate, and the maximum and (15.719 l/g VS) and minimum (4.454 l/g VS) biogas yield potential.

Optimized Conditions

The present investigation reports the optimization of process parameters for biogas production from water hyacinth (Eichhornia crassipes). The different parameters like particle size, inoculum concentration, incubation temperature, metal ions and pH were optimized for biogas production. Maximum biogas was observed with water hyacinth of 1cm size, 40 % inoculum concentration. The temperature of 45°C along with neutral pH i.e. 7 was found to be most suitable for biogas production in the presence of manganese chloride (0.2 mM). Under optimized conditions, 44.9 l biogas/kg water hyacinth, 360.09 l/kg total solids and 397.95 l biogas/kg volatile solids were produced in a period of 40 days. The water hyacinth has proven to be a good source of biogas production and thus can be utilized as a potential feedstock for the biogas production.

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 (Eichhornia crassipes), an aquatic macrophyte, is a resource that has attracted a lot of interest in recent times. The physicochemical constituents of Eichhornia crassipes have been reported in some literature to constitute high carbon, nitrogen, phosphorus, potassium including other important micro and macronutrient like potassium and zinc. These findings by scientists informed its utilization in the assemblage of animal feed, bio-energy generation, pharmaceutical industries, and biofilters. The bioconversions of this problematic plant to various products (compost, biochar, and digestate) are green inexpensive options to be considered for use in the restoration of hydrocarbon polluted sites is reviewed in the paper. In addition to crude oil pollution clean-ups, compost improves soil fertility and also increases its organic matter content. This article also shall review composting, Water Hyacinth compost applications in remediation, remediation monitoring parameters, limitations of remediation by composting technology, and the way forward.

Biogas is  one of energy   that can be produced by anaerobic fermentation of the organic compounds. The objective of this study was to determine the effectiveness of the utilization of waste of media  mushroom growth (baglog) with sawdust as raw material for biogas with  cow dung  activators. The study was conducted through anaerobic fermentation of the samples containing waste baglog (sample 1) and sawdust (sample 2), with the addition of cow manure activator to each sample. Both of these samples do anaerobic fermentation for 32 days, then measuring the volume of biogas every 4 days for 32 days. Methane content  in  samples 1 and 2 measured by  using gas chromatography. To see the effect of the addition of activators cow dung biogas volume measurement was  carried out with  cow dung without addition baglog waste and sawdust. The process of degradation baglog and sawdust with an activator of cow dung could be observed  in  some of the parameters through  total solids (TS), total volatile solids (TVS), volatile fatty acids (VFA), the degree of acidity (pH), and C/N ratio. The results showed that effectiveness of sample 1 resulted in the everage of total volume biogas 28% higher than  sample 2. The content of methane in  sample 1  and sampel 2  was 54% %, and 0.21% respectively. The fermentation process biogas production in this experiment  was carried out  at pH 7, with a value of TS, TVS and VFA showed a decrease  trend after the fermentation process,  C/N ratiowas  lower than the baglog waste sawdust until day 32 retention time.
