Description: THE ADVANCED ORGANIC WASTE GASIFIER (AOWG) IS A TECHNOLOGY DESIGNED TO CONVERT ORGANIC WASTES GENERATED DURING HUMAN SPACEFLIGHT INTO CLEAN WATER FOR MISSION CONSUMABLES AND GASES SUITABLE FOR VENTING TO MINIMIZE VEHICLE MASS FOR MARS TRANSIT AND RETURN MISSIONS. THE AOWG INTEGRATES STEAM REFORMATION, METHANATION, AND ELECTROLYSIS TO CONVERT ORGANIC WASTE INTO WATER, DRY VENT GAS, AND A SMALL AMOUNT OF INORGANIC RESIDUE, THEREBY REDUCING TRANSIT PROPELLANT AND TANKAGE MASS. THE AOWG REDUCES RISKS ASSOCIATED WITH STORING, HANDLING, AND DISPOSING FOOD WASTE AND PACKAGING, WASTE PAPER, WIPES AND TOWELS, GLOVES, FECAL MATTER, URINE BRINE, AND MAXIMUM ABSORBENCY GARMENTS IN MICROGRAVITY ENVIRONMENTS. THE REFORMER PROVIDES NEARLY COMPLETE CONVERSION OF FEEDS TO VALUABLE WATER AND JETTISONED GAS WITH MINIMAL LOSSES AND CONSUMABLES REQUIREMENTS WHILE OPERATING AT PRESSURES JUST ABOVE THE AMBIENT ENVIRONMENT. THE BASELINE AOWG PHASE II DESIGN INCORPORATES SIGNIFICANT NOVEL ENHANCEMENTS TO PREVIOUS STATE-OF-THE-ART TRASH TO GAS (TTG) STEAM REFORMING TECHNOLOGY INCLUDING A FEED SHREDDER, FEED DRYER, CONTINUOUS FEEDER, TAR DESTRUCTION REACTOR, AND WATER PURIFICATION. THE LARGELY AUTOMATED AOWG LIMITS CREW OPERATION REQUIREMENTS PRIMARILY TO LOADING PACKAGED WASTES INTO THE FEED HOPPER AND OCCASIONAL DISCHARGE AND COMPACTION OF ASH RESIDUE. THE PROPOSED PHASE II AOWG WILL BE DEVELOPED WITH A FOCUS ON ACHIEVING COMPLETE ORGANIC WASTE GASIFICATION SIMULTANEOUS WITH MAXIMUM WATER PRODUCTION USING FEEDING, MATERIALS HANDLING, AND ANCILLARY SYSTEMS GEARED TO MICROGRAVITY OPERATIONS. THESE CONCEPTS WILL BE INTEGRATED INTO A PROTOFLIGHT PHASE II DESIGN, WHICH WILL CONSIDER AND ACCOMMODATE THE MICROGRAVITY ENVIRONMENT NECESSARY TO OPERATE THE AOWG THROUGH STARTUP, STEADY OPERATION, AND SHUTDOWN. THIS PROGRESSION OF DEVELOPMENT WILL LEAD TO IMPLEMENTATION IN ADVANCED HUMAN SPACE MISSIONS.
