Waste management for Space Station Freedom.

Because of the tremendous task of designing, testing, building and maintaining the waste systems for Space Station Freedom, different methods of managing these systems are now being developed. This paper summarizes some of those methods. The first task for the design engineer is to develop systems and hardware to handle waste in the special conditions of the space station. Different closed and open loop systems, along with the development of new hardware in these loops, are being tested to meet this task. Some of the new hardware to be discussed are water and air monitors, hazardous material handling, and plumbing hardware such as commodes, showers and clothes washers. The second task is to develop methods to manage the process of developing these systems. Some of the areas to manage are testing information, materials, facilities, people, budgets, time, safety, legal responsibilities and testing standards. The last task is to incorporate the new technologies for other areas besides space stations. Other areas would include long-duration space missions, lunar stations and other non-space applications.
