Abstract: Access to clean water remains one of the most urgent environmental concerns, especially in developing regions where household and industrial activities are major contributors to water pollution. Women frequently assume responsibility for water management in domestic and community settings, positioning them as important actors in advancing environmental sustainability. This study examines the utilization of eggshell waste, commonly produced in households and small-scale culinary businesses, as a low-cost and sustainable material for water purification. Eggshells are rich in calcium carbonate (CaCO₃) and possess a naturally porous microstructure. The preparation process involved washing, drying, grinding, and calcination at 450 ℃ to obtain a functional adsorbent. Structural and surface characterizations confirmed that the material retained its integrity and exhibited adequate properties for adsorption. Application tests using methylene blue (MB) as a model pollutant demonstrated a degradation efficiency of up to 91.75%, indicating the material’s strong potential for wastewater treatment. Beyond technical performance, the study emphasizes the significance of linking scientific innovation with women’s roles in environmental management. By transforming household waste into an effective purification material, this research illustrates how women can be empowered as agents of change, supporting circular economy practices and sustainable community development. The findings highlight the dual benefits of waste valorization and gender inclusivity in addressing global water challenges, while also encouraging interdisciplinary collaboration across material science, environmental studies, and gender perspectives to strengthen the long-term sustainability of water resources.
