To learn more look to this study on laboratory autoclaves.
Usually, autoclaves require a sealed pressurised environment to generate saturated steam from water by raising the temperature to 121 °C or more for at least 15 minutes. This process turns autoclaves into a major source of water consumption in labs and medical facilities.
How to save energy and water?
Perform a facility survey to identify what types of autoclaves are installed and what type of water conservation solution would be appropriate. There are two most common types of steam sterilizers: gravity displacement autoclaves and high-speed pre-vacuum autoclaves.
Consider purchasing new research-grade autoclaves that are more energy-and water-efficient compared to medical-grade autoclaves.
Shut autoclaves off when not in use, e.g. at night and over the weekends.
Run autoclaves as efficiently as possible. Do full loads only, and avoid running an autoclave to sterilize, for example, just a single box of pipette tips.
Right size your autoclave. If you do not need a large autoclave, use a smaller one instead.
Install water-saving and/or water-cooling devices on existing autoclaves whenever possible.
Autoclaves: How to save energy and water?
Autoclaves are commonly used to sterilise equipment, reagents, and hazardous waste in labs. They are a major source of water consumption in labs and medical facilities.
