Enhanced humic-like acid formation from waste activated sludge during alkaline thermal hydrolysis - Dual role of reducing sugars.
Recovering humic-like acids (HLAs) from waste activated sludge (WAS) using alkaline thermal hydrolysis (ATH) offers a promising route for simultaneous sludge reduction and resource recovery. However, the limited content of readily reactive organic compounds in WAS constrains HLA yield. In this study, fruit waste (FW) a...
