Human waste disposal refers to the methods used to manage and eliminate human excreta, primarily through systems like sewage treatment plants and latrines. Proper disposal is essential for public health, as it helps prevent the spread of diseases and protects the environment from contamination. Common methods of disposal include composting toilets, which convert waste into compost, and septic systems, which treat waste on-site. In urban areas, waste is typically transported through sewer systems to treatment facilities, where it is processed and released safely into the environment.
