Evaluation of banana cellulose filler impacts on bioplastic films formulated from potato peel starch Badhane Gudeta Next Materials, 2026 The global proliferation of non-biodegradable plastic waste has necessitated the exploration of sustainable alternatives such as bioplastics. This study explores the development and characterization of biodegradable bioplastic films derived from potato peel starch (PPS), reinforced with banana pseudo-stem cellulose fiber (BPCF), both of which are underutilized agricultural wastes. Bioplastic films were produced by blending PPS with varying BPCF concentrations (0 %, 5 %, 10 %, 15 %, 20 %, and 25 % dry weight basis) and evaluated for their physicochemical, mechanical, and biodegradability properties. Fourier-transform infrared (FTIR) spectroscopy and X-ray Diffractometer (XRD) confirmed the presence of key functional groups and crystallinity respectively by indicating the successful interaction and structural integrity of the starch- cellulose matrix. The film with 15 % BPCF exhibited optimal performance, showing enhanced tensile strength (10.52 MPa), reduced moisture content (16.64 %), lower water solubility (26.22 %), and moderate acid-base resistance. Although its biodegradability (25.48 % in 15 days) was lower compared to the control (42.38 %), this reduction was attributed to increased crystallinity due to cellulose incorporation. The novelty of this work lies in the combined utilization of potato peel starch and banana pseudo-stem-derived cellulose, and in the comprehensive evaluation of chemical resistance. An area largely overlooked in previous studies. These results support the development of cost-effective, environmentally friendly bioplastics for sustainable packaging applications.
Physiochemical Analysis of Drinking Water and Treatment with a Homemade Filter: A Case Study of Illu Abba Bor Zone, Ethiopia Badhane Gudeta, M. Venkata Ratnam, Raja Mohan Genetics Research, 2022 The drinking water quality was evaluated in order to provide a continuous supply of clean and safe drinking water for the preservation of public health. The study area consists of three villages: Tulube, Seddo, and Serdo, all of which are located near Mettu town, which is about 550 kilometers south-west of Ethiopia’s capital, Addis Ababa. The physical and chemical parameters of the collected drinking water samples were assessed, including pH, turbidity, conductivity, total suspended solids (TSS), total dissolved solids (TDS), and the presence of heavy metals. The samples were examined in the laboratory, and the findings were compared to the World Health Organization (WHO) standards. Almost all of the physiochemical indicators were safe and within the permissible limit for drinking water quality. However, lead ion concentrations were found to be above the WHO standards. An adsorbent produced from banana pseudostems was used to remove lead ions from drinking water. The equilibrium parameters were determined using the Langmuir adsorption isotherm. The drinking water was treated for 4 h in a homemade adsorption column composed of filter medium (sand, charcoal, and powder of treated banana pseudostem). The data revealed that lead ions removal was nearly 70%, but still above the WHO standards.
Toxic Metal Recovery from Waste Printed Circuit Boards: A Review of Advanced Approaches for Sustainable Treatment Methodology Murugesan Manikkampatti Palanisamy, Venkata Ratnam Myneni, Badhane Gudeta, Srikanth Komarabathina Advances in Materials Science and Engineering, 2022 The rapid advancement of technical advancements has resulted in the generation of substantial amount of electronic trash (e-waste). The volume of e-waste created, as well as the presence of both dangerous and beneficial elements, enhances the business potential of recovery and recycling significantly. Waste printed circuit boards (PCBs) include a number of hazardous heavy metals, including copper (Cu), tin (Sn), lead (Pb), and others (Zn, Ni, Fe, Br, Mn, Mg etc.). These discarded metals without treatment threaten the economy, the environment, and human health. Heavy metal recovery from PCBs is a big difficulty for researchers. The present review focuses on technological advances in the recovery of toxic, precious metals from PCBs.
Bioinsecticide Production from Cigarette Wastes Badhane Gudeta, Solomon K, M. Venkata Ratnam International Journal of Chemical Engineering, 2021 Tobacco, one of the most significant nonfood crops, is critical to agriculture worldwide. The tobacco processing business creates a significant amount of hazardous tobacco waste containing nicotine, and only a tiny portion of it gets recycled. Nicotine, the primary component of tobacco products such as cigarettes, is an alkaloid and can be used as an insecticide. This research aims to extract nicotine from discarded cigarette butts and utilize it as an insecticide. Extraction, emulsification, and efficiency testing on cabbage aphids are all part of the procedure. The initial extraction tests used a solvent combination of ethanol and methanol in various ratios, with a 3 : 1 ratio yielding the best results. Temperature (30–60°C), extraction length (4–6 hrs), and sodium hydroxide concentration (1–3 M) are the independent variables studied for extraction parameters, and the optimal conditions are determined using Design-Expert, response surface approach central composite design (RSM-CCD). In addition, artificial neural network (ANN) studies with MATLAB were used to accurately forecast extraction yield. The extracted product was evaluated using a gas chromatography–mass spectrometry (GC-MS) and a UV/visible spectrophotometer. The ideal crude extract yield and nicotine content were 17.75 and 3.26%, respectively, at the optimal conditions of temperature 60°C, time 4 hrs, and NaOH concentration 2.83 M with desirability of 0.832. The nicotine extracted was emulsified by combining the crude extract with a combination of palm oil and surfactants. Density, viscosity, pH, flash point, and surface tension of the emulsified concentration were measured and reported as 1.01 ± 0.01 g/ml, 585.33 ± 2.52 mPa s, 9.37 ± 0.03, 87.96 C, and 34.10 mN/m, respectively. On the cabbage aphid, the emulsified concentrated extract performed best at a ratio of 1 : 100 (emulsified concentrated to solvent).
