Description: Waste stowage and water reclamation is vital for long-duration space exploration missions. Current primary waste systems cannot reclaim water or effectively reduce the volume of trash generated by astronauts. It is imperative that we “close the loop” for human life support for these new missions. A Heat Melt Compactor (HMC) is a device that will recover residual water from astronaut’s trash (e.g. wet wipes, juice boxes) via evaporative heat transfer, and then compact the trash in a 10-to-1 ratio to provide volume reduction, or perhaps some usefulness as an ionizing radiation shield.

Benefits: The technology to reduce the volume of astronauts' day-to-day trash by residual moisture extraction will benefit future NASA missions into space.
