Utilization of Banana Peel Biopolymer as a Natural Coagulant for Wastewater Treatment: A Sustainable Approach to Bio-Composite Applications
Abstract: This study explores an eco-innovative approach to wastewater treatment by utilizing banana peel powder (BPP) as a sustainable, low-cost bio-coagulant. Although effective, conventional chemical coagulants like aluminum sulfate and synthetic polymers are often non-biodegradable, toxic, and economically burdensome, particularly in decentralized or low-resource settings. In contrast, BPP—an agro-waste material rich in bioactive functional groups such as hydroxyl, carboxyl, and phenolic compounds—provides a renewable and environmentally friendly alternative. To enhance its …

Managing Blow-by in Modern Engines: A Comprehensive Review of Crankcase Ventilation Technologies
Abstract: Blow-by in internal combustion (IC) engines occurs when high-pressure combustion gases escape past the piston rings into the crankcase. These gases typically carry oil aerosols, unburned hydrocarbons, and fine particulate matter, which, if not effectively managed, can disrupt lubrication, accelerate component wear, and contribute to harmful emissions. Effective crankcase ventilation is therefore essential not only for ensuring engine durability but also for meeting increasingly stringent emission regulations. This paper examines …
