Optimization of biogas production from water hyacinth (Eichhornia crassipes)

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.

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.

Water Hyacinth Root

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.

Negative Sentiment

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.

Global Concern

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.
