Additional bags for your PETT toilet system. WAG Bags can also be used in other "river style" toilet systems such as, Boom Boxes, Rocket Boxes, and various River bank toilets. The degradable WAG bag contains a bioactive non-toxic gelling powder that encapsulates liquid and solid waste, neutralizes odors, initiates and accelerates decomposition. Full bags can simply be put into the provided zip-close, puncture resistant containment bag, and thrown in any normal trash container. These bags comply with federal standards for disposal in landfills and will degrade along with gell and waste in six to eight months. Each bag is good for 3-4 uses.
