A composting toilet is a type of toilet that uses no water for flushing and instead relies on composting material to break down human waste. Composting toilets are often used in off-grid situations where there is no access to a water supply for flushing.

Instead, composting toilets use a variety of materials, such as sawdust, wood chips, or straw, to help break down human waste. The end result is a nutrient-rich compost that can be used to fertilize gardens or crops.

Conclusion

A composting toilet is a great option for an off grid toilet because it is environmentally friendly and does not require any water to flush. The waste is broken down by bacteria and turned into compost that can be used as fertilizer.

There are many different designs of composting toilets, so it is important to do some research to find the one that will work best for your needs.
