Development of an Efficient Sanitary Pad Shredding and Disposal System for Environmental Sustainability

Abstract: Improper disposal of sanitary pads contributes to environmental pollution, landfill accumulation, and public health risks due to non-biodegradable materials and potential pathogen transmission. This study proposes an innovative sanitary pad shredding and incineration system designed to minimize environmental impact while ensuring safe and efficient waste management. Through laboratory experiments, prototype testing, and stakeholder surveys conducted over a 3-year period (2022– 2025), we evaluated the system’s efficiency in reducing waste volume, neutralizing pathogens, and minimizing emissions. Results indicate that the proposed system achieves a 90% reduction in waste volume, 99.9% pathogen elimination, and compliance with air quality standards (PM2.5 < 25 µg/m³). Socio-economic assessments revealed that 70% of potential users (schools, hospitals, and communities) face barriers⅓ barriers to adoption due to high initial costs and lack of awareness. We propose cost-effective scaling strategies, including subsidies and awareness campaigns, to enhance system adoption. This research underscores the potential of the shredding-incineration system to address sanitary waste challenges while promoting environmental sustainability
