Demonstration of Plasma Assisted Waste Conversion to Gas

Metadata Updated: May 2, 2019

The goal is to demonstrate high fidelity mission waste simulant conversion with a proprietary DC plasma torch, a different approach from industry which uses higher powers not acceptable on the smaller scale of space missions. The baseline carrier gas will be 100% air, then the feasibility of alternate carrier gases (CO2, N2, and hydrocarbon product gas recirculation) will be evaluated. A CO2 carrier gas is ideal since it is a byproduct of human metabolic activity (available on ISS), and 95% of the Mars atmosphere. A semi-closed loop system could be achieved if the product gases produced by the trash conversion itself could be used as a carrier gas. As this this technology advances it would eventually be infused into future AES projects. The next steps would be to demonstrate up to three down-selected technologies in the combustion integration rack for microgravity experiments on board the ISS, and then build a flight unit for converting mission waste into gas to reduce volume, odor, and provide sterilization of waste.
