A simple and reliable concept for the collection, processing, disposal or storage of human waste products has been developed for application under conditions of weightlessness. Psychological acceptance is achieved by utilization of a hardware design permitting conventional earth-like procedures. Bag type containers are not used for collection and storage, thus manual handling of waste products and storage containers is not required. The system is capable of handling urine and fecal waste as well as Yomitus and food debris. The solids are vacuum dried to permit bacteriostatic storage and urine can be jettisoned to space.
