The work evaluates the energy recovery from hydrothermal carbonization (HTC) of cow manure through the thermal analysis of hydrochar and the anaerobic digestion (AD) of the process water (PW). The increase of the HTC temperature in the range of 170–230 °C improved solid-fuel properties (higher heating value (16.4–20.1 MJ kg⁻¹), fuel ratio (0.19–0.33)) of dairy manure, but less energy can be recovered by its combustion ascribing to reduction of hydrochar yield (65.0–54.0%). Fixed carbon content (12.5–18.7%), and ignition (263–278 °C) and burnout (581–619 °C) temperatures increased with carbonization temperature, thereby reducing risks of fire and explosion. However, the highest value of the comprehensive combustion index, related with good fuel characteristics, was obtained for the hydrochar carbonized at 170 °C. The high organic matter content of the PW allows energy recovery by AD, obtaining …
