Co-hydrothermal carbonization of agricultural waste and sewage sludge for product quality improvement: Fuel properties of hydrochar and fertilizer quality of aqueous phase

Guangchun Shan et al.

Summary: This study investigated the potential of co-hydrothermal carbonization (HTC) of sewage sludge (SS) with rice husk (RH) and wheat straw (WS) to produce hydrochar and aqueous phase (AP) as substitutes for fuel and chemical fertilizer, respectively. The results showed that co-HTC significantly increased the yield and higher heating value of hydrochar, improved its handling and combustion performance, and increased the nitrogen content in the AP. Co-HTC also enhanced plant growth by replacing chemical fertilizers with AP.

Summary: Hydrothermal treatment (HT) improves the pyrolysis of sewage sludge by reducing the activation energy and facilitating the formation of hydrocarbons and acids/esters. HT also reduces the nitrogen- and sulfur-containing compounds in bio-oil and non-condensable gases.
