Production of Eco-Friendly Paint from Cow Dung

Abstract The increasing environmental and health concerns associated with conventional synthetic paints have created a strong demand for sustainable and eco-friendly alternatives. Traditional paints often contain volatile organic compounds (VOCs), heavy metals, and petrochemical derivatives that contribute to air pollution and adverse health effects. In this context, the present study focuses on the manufacturing of eco-friendly paint using cow dung as a primary raw material, utilizing its natural binding, antimicrobial, and insulating properties. Cow dung is an abundantly available agricultural by-product in rural India and has been traditionally used for coating walls due to its durability and eco-friendly nature. In this project, cow dung is processed through drying, pulverization, and filtration, followed by blending with natural binders, fillers, and water to produce a usable paint formulation. The prepared paint is evaluated for parameters such as adhesion, drying time, surface finish, thermal insulation, and resistance to microbial growth. The results indicate that cow dung-based paint is biodegradable, non-toxic, cost-effective, and environmentally sustainable when compared to conventional paints. Additionally, it contributes to waste utilization and promotes rural resource-based industries. This study demonstrates the potential of cow dung as a viable raw material for green paint manufacturing and supports the development of sustainable construction materials with minimal environmental impact.
