Note: The above toilets have important differences. The Nature’s Head and Separett are urine seperating designs, while the Envirolet, Sun-Mar and Biolet combine the urine and solids. The Nature’s Head is a somewhat smaller toilet, and suitable for up to 2 people full time. The Biolet 10 is rated for 3 people. The Envirolet is rated for up to 8 people, the Sun-Mar Excel 3-4 people, and the Separett has unlimited capacity. (That is because the contents are removed from the Separett, in a compostable plastic bag, to complete the composting process in a secondary container).
