In a disaster situation, a critical part of preventing an outbreak of disease is the hygienic disposal of human waste. The UnBathroom biodegradable cardboard toilet offers a recyclable, sanitary solution. Allowing one liner bag and cardboard seat per use, it packs flat for shipping, assembles easily, and can support up to 200 pounds (91 kg). The waxed cardboard structure is intended to be burned after all the liners are used.
