Abstract
A human waste collection system, for zero-gravity conditions, the collection system having: a basin having a lower end that defines a lower plane and configured for being positioned against a floor and an upper end that is spaced apart from the lower end and displaced further from the plane than the lower end; a seat positioned at the upper end of the basin, the seat having a lid pivotally connected to the seat; a bag cassette disposed under the seat; and a compression ring that is movable within the basin to automatically pull an unused bag segment from the bag cassette, and push down used bags.
