American Innotek’s Restop 1 is a urine disposal unit, made as a small portable pouch with a contoured top. Absorbant polymers hold liquid as an odorless gel, the company says. Restop 2 is a disposable toilet. Both products are approved by the EPA. The Restop commode, a 5-gal. bucket, has a seat similar to traditional commodes and allows for longer waste storage before disposal.
