Abstract
A Microwave Powered Solid Waste Stabilization (MPSWS) system is proposed as the primary step in the treatment of solid waste materials generated during extended manned space missions. The proposed system will recover water initially contained within the wastes and stabilize the residue with respect to microbial growth. The dry waste may then be safely stored or passed on to the next solid waste treatment process. Using microwave power in a closed system, the MPSWS will selectively and rapidly heat the water present in solid wastes. Liquid phase water will flash to steam and superheat. The steam will contact all exposed surfaces and provide an effective thermal kill of all microorganisms present, in a manner similar to that of an autoclave. Both water and heat will be recovered in a condensing heat exchanger. Applicable solid wastes include, but are not limited to, inedible plant biomass, food scraps and fecal matter.
