Composting toilets are one of the hottest new trends in green living. Not only are the fixtures economical to buy and install, but they’re also great for the environment and your pocketbook. Eco-toilets are a great way to safely compost your waste while you are away from traditional toilet facilities. Eco-toilets are especially useful in disaster preparedness and camping trips. Composting toilets are clean, hygienic and easy to use. You can save enormous amounts of water by composting your waste rather than flushing it. Toilets come in a variety of styles and models. Some of which are one-piece models and others two-piece units.
