Solid waste refers to any type of discarded garbage, excluding wastes such as sewage, irrigation flow, and certain hazardous materials. Solid waste pollution is common in urban areas and is dangerous to human health:

• It may cause diseases such as dysentery, cholera, jaundice, and salmonellosis.
• Storing solid waste in landfills and burning it leads to secondary pollutant problems, including the release of toxins into the air and water, which greatly impacts nearby neighborhoods.
• Improper solid waste management has been linked to the development of cancer, respiratory diseases, and nervous system damage.
