The Peepoo bag is a long thin bag with a lined with gauze that is distributed to populations with inadequate options for dealing with human waste. The inside of the biodegradable bag is coated with urea, a non-hazardous chemical fertilizer. Once urine or feces make contact with the urea, decomposition begins.

The material is broken into ammonia and carbonate, driven by naturally occurring enzymes in the waste. As the urea is broken down, the acid value of the material increases and sterilization of the waste begins. Viruses, bacteria and parasites carried in the waste are killed over a period of a couple of hours to a few weeks.
