Ecotoilets have made their way into the markets now! It is a low weight and portable and eco-friendly toilet which is perfect for camping, bird-watching, boating, hiking and other outdoor activities. This is also essentially suited for disaster preparedness in classrooms, daycare centers, and other venues where students are present.

The waste bags that come with the toilet are made of Mater-Bi corn starch and are 100% biodegradable and compostable. Nature Bio-Bags can also be used with most existing portable toilet systems. When camping, or using the same, it is however important that people bury or dispose of bags in the appropriate waste receptacle and leave the site as clean as they found it.
