10.5 Conclusions

This chapter has assessed resource recovery from high moisture biogas digestate feed-
stock using a hydrothermal liquefaction (HTL) processing pathway as a technically
and economically viable digestate management strategy. Comparative assessments
of the economic performance of the HTL-based one-step digestate processing technol-
ogy as an alternative processing technology to the existing digestate processing
