► Biochars from anaerobically digested biomass effectively removed heavy metals. ► Lead sorption capacities of the biochars were close to or higher than 200mmol/kg. ► Surface precipitation was the governing heavy metal removal mechanism. This study examined the ability of two biochars converted from...
