Dry toilets, also known as composting toilets, are sanitation systems that do not use water for flushing. Instead, they collect human waste in a container, where it decomposes naturally through aerobic processes. This method reduces water usage and can help recycle nutrients back into the soil. These toilets are often used in areas without reliable water supply or sewage systems. They can be found in rural homes, campsites, and even some urban settings. Dry toilets contribute to sustainable living by minimizing environmental impact and promoting resource conservation, making them an eco-friendly alternative to traditional flush toilets.
