Waste Management: Toilet, showers, garbage disposal.
- Waste management in space is rather interesting. Astronauts use flushing toilets that flush with air rather than water. The airflow draws the waste away from the body, and then flushes it into the storage tanks. The liquid eventually evaporates once it’s dumped overboard. Solid waste goes into a container, dries out, and is taken back to earth for disposal.
