Potential NASA Commercial Applications: The proposed approach will make it technically feasible to process human fecal waste and wet mixed waste streams and produce additional water and other useful products in space which will benefit long term space travel, such as an extended Lunar stay or a mission to Mars and Asteroids/Phobos. It is beneficial to NASA in also allowing for solid waste sterilization and stabilization, planetary protection, in-situ resource utilization (ISRU) and/or production of chemical feedstocks and carbon materials. In particular, the solid residue has several potential applications in space. These include production of activated carbon, a nutrient-rich substrate for plant growth, as a filler for polymers and composites, radiation shielding, carbon/hydrogen storage, and fuel gas (CH4, CO, H2) production. In addition to its primary purpose to process fecal waste, torrefaction could potentially be beneficial for other types of wastes, including food wastes, wipes, clothing, and brine.
