Co-digestion of food waste and hydrothermal liquid digestate: Promotion effect of self-generated hydrochars. [PDF]
Environ Sci Ecotechnol, 2023 Hydrothermal treatment (HTT) can efficiently valorize the digestate after anaerobic digestion. However, the disposal of the HTT liquid is challenging. This paper proposes a method to recover energy through the anaerobic co-digestion of food waste and HTT liquid fraction.
