Several methods have been proposed in the literature to deal with the problem of organic waste and wastewater in space. Among these, supercritical water oxidation (SCWO) has been identified as one of the most promising candidate owing to its advantages over its competitors [1]. In addition to exhibiting characteristic properties of a supercritical fluid, such as high compressibility, supercritical water (SCW) behaves as a non-polar solvent in contrast to being polar at ambient conditions. Consequently, it acts as a very good solvent for organic matter and several non-polar gases, such as oxygen, nitrogen etc., which makes SCW a homogenous medium for the oxidation of organic matter. This forms the underlying principle of SCWO...
