In 1971, Hardy Sundberg developed the world's first self-contained composting toilet.
For the first time a self-contained toilet could be put in a bathroom and would evaporate liquids and compost solids.

What is Composting?

• Composting converts organic matter back to its essential minerals
• Aerobic Micobes do this in the presence of moisture and air, by oxidizing the carbon in the organic material to carbon dioxide gas, and converting the hydrogen atoms to water vapor.
• In this process, some 95% of the starting material volume (largely moisture) is evaporated, so the residential salts are easy to handle.
• This resulting compost provides the essential food for uptake by plants. So it is perfect for recycling.
