Hydrothermal carbonization (HTC) emerges as a promising technology to reduce the volume of activated sewage sludge (SS) and generate solid products as fuels. During HTC, extracellular polymeric substance and cell wall degrade to form low molecular compounds, which can further carry out hydrolysis, d...
