Self-contained composting toilets feature a toilet seat with a waste container permanently attached underneath it. Remote composting toilets have a composting site located separately, so the waste has to be moved. Batch composting toilets have multiple containers for waste, allowing users to rotate or switch between them. Continual process composting toilets have an extra-large container where the waste is collected. The compost is harvested from the bottom on an ongoing basis. [3] X Research source
Note that composting toilets are not pit toilets. A pit toilet is basically a giant hole in the ground where waste collects and contaminates the soil. [5] X Research source Many cabins have pit toilets, but composting toilets are better because they don’t harm the local environment.
If you don’t have sawdust, you can use handfuls of peat moss or coconut coir. [7] X Research source
Composting can take anywhere from a few weeks to several months, depending on the volume of waste and other factors. [9] X Research source
The temperature needs to be kept between 60-150°F (16-65°C). An electric heater can help maintain higher temperatures. Fans can promote air circulation, which provides oxygen to aerobic bacteria.
Composting toilets can be safer than septic tanks—which can easily leak—since properly composted waste is less likely to contaminate groundwater. [11] X Research source
Some towns and jurisdictions don’t permit composting toilets, or only allow them in certain cases. Check your local laws before purchasing one. [14] X Research source
The frequency of maintenance depends on the size of your composting bin. Large composting toilets may only need to be emptied every few months, whereas small ones will require more frequent emptying.
Wear gloves when handling human waste. Wash your hands thoroughly. Never forget to add sawdust or some other bulking agent after each use. This is essential for proper composting
