Opis:: Currently, lithium-ion batteries still use electrodes from graphite, which is a natural resource for non-metallic minerals. As a sustainable plan, research on the manufacture of lithium-ion batteries based on biomass electrodes has prospects for commercial development. In this study, carbon stems of water spinach (Ipomoea Aquatica) were used as electrodes on the battery. Water spinach is processed into nanocarbon by hydrothermal method and pyrolysis. The size of the nanocarbon particles from water spinach in this study was 200 mesh resulting from the grinding method. The type of battery made is a bag battery with a size of 8×12 cm by performing variable optimization by using a concentration of 50% LiCl/Li2SO4 electrolytes media, Polyurethane/Polyacrylate binder, and Triethylamine/Non-emulsifier. The highest power and energy values are generated from carbon based lithium-ion batteries from water spinach with LiCl electrolyte media, Polyurethane binder, and Triethylamine emulsion which is 5.404 W and 4.511 W∙h.

Opis:: Owing to its high concentrations of nitrogen and phosphorus, the slurry from water hyacinth (Pontederia crassipes) biogas production cannot be discharged directly without further treatment. To achieve the target of water recycling, a new strategy of combining a Carrousel oxidation ditch with a water spinach wetland was developed in this study for the harmless treatment of Pontederia crassipes biogas slurry. First, the water quality characteristics of the biogas slurry were measured. Then, comprehensive tests of the combined slurry treatment system were carried out to verify pollutant removal performance and mechanism. The results showed that the Carrousel oxidation ditch reduced the inlet pollutant load of the subsequent water spinach wetland. The chemical oxygen demand (COD), and ammonium nitrogen (NH4+-N), total nitrogen (TN), and total phosphorus (TP) contents of the average effluent from the combined system were less than 50 mg/L, 1.6 mg/L, 6 mg/L, and 0.5 mg/L, respectively, which means that all met urban sewage treatment standard of Level 1 Grade A (GB18918-2002). Gas chromatography – mass spectrometry analysis showed that the combined system had decreased various types of organic pollutants in the biogas slurry exponentially, efficiently removing alkane pollutants, aromatic hydrocarbons, and heterocyclic compounds. Scanning electron microscopy images revealed very large surface area of the water spinach roots in the wetland, which played important roles in enriching the microorganisms and trapping organic matter. Plant absorption, microbial degradation, and filtration were the primary ways in which the water spinach wetland purified the biogas slurry.

Opis:: Water is a limited resource, hence there is a need for its judicious use. This study was designed to investigate the utilization and the effects of grey water irrigation on the growth parameters of African spinach (Amaranthus hybridus) and its soil properties when planted in a green house. The irrigation treatment consisted of Tap water (TW) and grey water (GW) collected from Akindeko Hostel in Federal University of Technology, Akure. The vegetables were planted in five bucket samples for each irrigation treatment. The water samples were assessed to determine chemical properties, while soil samples were collected and analysed before irrigation application and after harvest. Crop morphology that includes the plant height, number of leaves and stem girth parameters were recorded weekly after emergence. Our results indicate that the grey water type has the highest chemical parameters. These included TSS, SAR, pH, HCO3ˉ, Ca2+, Mg2+, and Na+. What is more, soil pH decreased in all the soil samples after the different water applications, the lowest pH being from grey water. The sodium adsorption ratio (SAR) also decreased in all the irrigation treatments. In addition, the plant height, number of leaves and stem girth of the crop were affected by the water type used. Herein, the crop irrigated with grey water had the highest morphology parameters. Furthermore, soil chemical properties were significantly affected by the use of grey water, hence, appropriate wastewater treatment and water management practices have to be followed to remove the toxic elements that could be hazardous to human health when crops produced on them are consumed.
