Biochars (BCs) were produced by pyrolysis of dry sewage sludge (DSS) in order to stabilize the heavy metals (HMs). The physicochemical transformations of HMs were studied during pyrolysis at different temperatures (500-700 oC) in a fixed bed reactor. The produced BCs and DSS were introduced into com...
