of the aqueous phase is extremely important to be considered. However, the treatment of aqueous effluent is costly
and diminishes the process economy of the HTL process.
Thus, it is essential to explore the ways for recovering
non-polar organic fractions micro- and macronutrients that
existed in aqueous phase (Madsen et al. 2016).
There are some alternate ways for the valorization of
aqueous phase that are widely discussed in many publications, like catalytic hydrothermal gasification (CHG),
anaerobic digestion and recirculation of residual water to
HTL system. Elliott et al. suggested the CHG to recover the
methane gas for process integration (Elliott et al. 2015).
