The choice of feedstock for biogas production should not only be limited to organic waste like agricultural products, food, and animal waste. Human feces could also be considered a source of biogas production. The ever-increasing cost of fossil fuels and environmental pollution threats are forcing the search for alternative energy sources. Several types of research have to unlock the mysteries behind the difficulties of producing biogas from human feces, especially the production of more HN 3 , which is a greenhouse gas because of its low C:N ratio. This research experimentally investigated how to reduce their amount using rice straw with a high C:N ratio. Several combinations were made between the human waste and the rice straw at different ratios during the experiment. The result shows that the optimal outcome for methane production fell on the 50% HF and 50% RS combination due to the actions of both aerobic and anaerobic processes.
The textile industry’s discharges have long been regarded as severe water pollution. The photocatalytic degradation of dyes using semiconductors is one of the crucial methods. The present study efficiently used the mechanical method to synthesize Iron oxide Nanoparticles. XRD, FT-IR, UV-Vis DRS, and Raman analyses were performed to analyze the structural and optical. From the data provided by XRD and Raman data, we believed that the as-synthesized Iron oxide was pure hematite (α-Fe2O3) with a hexagonal structure. Additionally, the EDS results show that the synthesized material is pure. By adjusting specific parameters, including the dye concentration, the catalyst dosage, the pH, and the oxidizing agent such as H2O2 and K2S2O8, the degradation of eosin yellowish using Fe2O3 as a photocatalyst has been discussed. Additionally, the kinetics of eosin yellowish degradation has been studied. A study was also conducted using Fe2O3 nanoparticles attached to polyurethane polymer (PU) to investigate its photocatalytic activity on methylene blue, methyl orange, and indigo carmine. In 30 minutes, nearly 90% of the dyes had degraded. The total organic carbon (TOC) analysis confirmed this result.
The use of antibiotics has become imperative and unavoidable in medicine to Figureht against microbes, but the majority of these antibiotics are found in environmental ecosystems. It is revealed that the presence of these in the environment, intoxicates the bacterial ecological medium.Then, this investigated the phytoremediation abilities of Water lettuce (Pistia Stratiotes). Adolescent plants were placed in two different concentrations of Ciprofloxacin solution for 7 days. The aim was to see if the plant could remove the Ciprofloxacin, what amount of it and the effects of the drug on the plant thereafter. The concentrations were 50ppm and 10ppm of Ciprofloxacin. The result was that at 50ppm, the plants developed necrosis within 3 days and died. At 10ppm solution, water lettuce managed more than 70% removal efficiency, and also a steady growth of the plant was maintained at 0.1606 g/day. For the concentration of Ciprofloxacin, analysis of sample water was done using UV-Visible Spectroscopy and plant extract was analyzed by HPLC. The study proved that water lettuce can be used as a remediation technique for surface waters, or can be an end-of-pipe measure for pharmaceutical wastewater treatment facilities before discharge into surface waters.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
