Abstract - This paper presents the development and evaluation of an eco-friendly paint formulation utilizing cow dung as a primary raw material. A novel machine was designed and fabricated to efficiently process cow dung, transforming it into a suitable pigment for paint production. The paint formulation incorporates key additives such as calciumcarbonate, titanium dioxide, xanthumgum, a binder, and sodium benzoate to enhance its properties. The performance of the developed paint was assessed in terms of its color, opacity, adhesion, and durability. The results demonstrate the feasibility of producing high-quality, ecofriendly paints from a readily available and sustainable resource like cow dung, offering a promising alternative to conventionalpetroleum-basedpaints.Thisprojectcontributes to sustainable practices in the paint industry by utilizing a waste product and reducing environmental impact.
Key Words: Eco-friendly paint, pigment development, sustainable resource
1.INTRODUCTION
The global paint and coatings industry faces increasing pressure to minimize its environmental impact. Conventionalpaintformulationsrelyheavilyonpetroleumderived raw materials, contributing to greenhouse gas emissionsandresourcedepletion.Furthermore,thedisposal of synthetic paints poses significant environmental challenges. To address these concerns, there is a growing interest in developing eco-friendly alternatives utilizing renewableandsustainableresources.
Cowdung,anabundantagriculturalbyproduct,presentsa potential sourceofnatural pigments for paintproduction. Previousstudieshaveexploredtheuseofanimalwastein various applications, including biofuels and fertilizers. However,theutilizationofcowdungasapigmentforhighqualitypaintformulationsremainsrelativelyunexplored.
