This study focused on developing an eco-friendly, fire-resistant coating using natural waste materials, including avocado seeds and chicken eggshells. It addressed the need for sustainable and cost-effective alternatives to traditional fire retardants, which often contain harmful chemicals. The study aimed to determine whethSer these agricultural byproducts could be transformed into a fire-resistant material suitable for combustible surfaces, specifically testing the product on linen fabric. Linen fabric samples were coated with three treatment formulations and compared with uncoated fabric through flame spread and drying time tests. Results showed that the coating reduced flame spread compared to uncoated fabric. A key finding was the synergistic effect between the calcium carbonate in eggshells and the organic compounds in avocado seeds, which enhanced the coating’s thermal resistance. The study rejected the hypothesis that the ratio of the two ingredients would significantly affect the coating’s effectiveness; the coating remained consistently fire-resistant across all proportions. In conclusion, the study demonstrated that avocado seeds and chicken eggshells are viable and sustainable raw materials for producing effective fire-resistant coatings. The findings support their use as eco-friendly alternatives to synthetic fireproofing products. Future studies are encouraged to investigate other natural sources, evaluate the coating on various surfaces, enhance transparency and appearance, and simulate real-world fire conditions to facilitate broader application.
