Solid waste management encompasses the systematic collection, transportation, processing, recycling, and final disposal of non-liquid waste materials generated by human activities. Designed to safeguard public health and protect natural ecosystems, modern waste management relies on the waste hierarchy framework, which prioritizes waste reduction, reuse, and recycling over land disposal. By diverting organic matter to composting facilities, recovering valuable materials like metals, glass, and plastics, and converting non-recyclable refuse into energy, municipal systems minimize the strain on overflowing landfills. Effective solid waste management significantly reduces soil and groundwater contamination, mitigates greenhouse gas emissions such as methane, and conserves raw natural resources, making it a crucial component of sustainable urban development and the circular economy.
