    • An Assessment of the Water Extraction Capabilities of the Heat Melt Compactor 

      Alba, Richard; Harris, Linden; Wignarajah, Kanapathipillai; Fisher, John; Hummerick, Mary; Pace, Gregory; Delzeit, Lance; Larson, Brian (44th International Conference on Environmental Systems, 2014-07-13)
      The Heat Melt Compactor (HMC), a waste management technology developed at the NASA Ames Research Center, was designed to process waste generated aboard spacecraft. The device compacts, encapsulates and sterilizes the waste ...
    • Development of an Adsorption System for the Trash Compaction Processing System designed for operation in the International Space Station Express Rack 

      Pace, Gregory; Lee, Jeff; Parodi, Jurek; Richardson, Justine; Trieu, Serena; Young, Janine; Martin, Kevin (2020 International Conference on Environmental Systems, 2020-07-31)
      A water recovery system that utilizes adsorption to work with the Trash Compaction Processing System, formerly known as the Heat Melt Compactor, is being designed at NASA Ames Research Center as an option to current state ...
    • Gas Effluent Analysis of the Heat Melt Compactor 

      Young, Janine; Trieu, Serena; Parodi, Jurek; Richardson, Tra-My Justine; Lee, Jeffrey; Martin, Kevin; Pace, Gregory (2020 International Conference on Environmental Systems, 2020-07-31)
      The Heat Melt Compactor (HMC) reduces volume, heat sterilizes, stabilizes, and manages gas and water effluent of the International Space Station (ISS) trash. Processing the trash at high temperatures produces volatile gas ...
    • Generation 2 Heat Melt Compactor Development 

      Turner, Mark F.; Fisher, John W.; Broyan, James; Pace, Gregory (44th International Conference on Environmental Systems, 2014-07-13)
      NASA has been developing a waste management device for human space exploration missions called the Heat Melt Compactor (HMC) as part of the Advanced Exploration Systems (AES) Human Spaceflight Logistics Reduction and ...
    • Heat Melt Compactor Development Progress 

      Lee, Jeffrey; Fisher, John; Pace, Gregory (47th International Conference on Environmental Systems, 2017-07-16)
      The status of the Heat Melt Compactor (HMC) development project is reported. HMC Generation 2 (Gen 2) has been assembled and initial testing has begun. A baseline mission use case for trash volume reduction, water recovery, ...
    • Membrane Distillation Driven by Embedded Thermoelectric Heat Pump 

      Lee, Jeffrey; Delzeit, Lance; Parodi, Jurek; Pace, Gregory; Trieu, Serena (48th International Conference on Environmental Systems, 2018-07-08)
      Membrane distillation is a method that recovers clean water from dirty water by way of the vapor pressure difference of water across a membrane. External systems typically provide the heat necessary to maintain the vapor ...
    • Processing of Packing Foams Using Heat Melt Compaction 

      Harris, Linden; Alba, Richard; Wignarajah, Kanapathipillai; Fisher, John; Monje, Oscar; Maryatt, Brandon; Broyan, James; Pace, Gregory (44th International Conference on Environmental Systems, 2014-07-13)
      Foam is used extensively as packing material for items sent to the International Space Station (ISS). Although lightweight, foam is bulky and can occupy a large fraction of the limited ISS volume. Four chemically distinct ...
    • Space Mission Trash Processing Operational and Technical Limits 

      Lee, Jeffrey; Martin, Kevin; Feller, Jeffrey; Pace, Gregory; Parodi, Jurek; Trieu, Serena; Kashani, Ali; Helvensteijn, Ben (49th International Conference on Environmental Systems, 2019-07-07)
      Trash management is a critical logistic and life support function for future long duration missions. The Heat Melt Compactor (HMC) has been developed to examine the operational processes and technical limits for space ...
    • Technical Risks Associated with Heat Melt Compaction Systems 

      Lee, Jeffrey; Richardson, Tra-My Justine; Martin, Kevin; Young, Janine; Pace, Gregory; Parodi, Jurek; Trieu, Serena; Helvensteijn, Ben; Ewert, Michael (2020 International Conference on Environmental Systems, 2020-07-31)
      The processing of trash and waste is a welcome and valuable addition to humans living and working in space. Besides the obvious desire to have a pleasant and productive habitation environment, trash management has many ...
