Solid waste management
All waste produced by the crew cannot be stored on board a spacecraft, mainly for safety and volume limitation reasons. For long-duration missions, safety and available storage volume become more stringent constraints. Waste recycling for oxygen and water production and subsequent food production therefore becomes a necessity.
Several technologies have been investigated, from microbial (anaerobic fermentation, rumen bacteria) to physical-chemical techniques (wet oxidation, super critical water oxidation) and hybrid systems. These investigations are undertaken within the MELiSSA project
