Synergistic Stabilization of Heavy Metals during Co-Hydrothermal Carbonization of Sewage Sludge with Lignocellulosic Biomass: Speciation Transformation, Risk Reduction and Sustainability Assessment
With increasing concerns over contamination by heavy metals (HMs) in sewage sludge, treatment technologies integrating detoxification and resource recovery are urgently needed. This study used sewage sludge (SS) and four lignocellulosic biomasses, including pine sawdust (PS), bagasse (BS), sunflower straw (SFS), an...
