Abstract

Landfill and dump remediation and waste recovery are often needed as circular economy approach is more and more demanding. Complicated solutions are needed to conserve the landfill space as well as overall reduction of the amount of landfilled material is not an easy task because of the different content of contaminants. Primitive soil excavating and transporting to hazardous waste landfills is not the best solution anymore. Series of experiments using landfill mined fine fraction of waste considering complex forming stability of contained copper and lead were performed. Experiments have shown that stability constants overall are enough convincing that inert fine fraction of waste with added soil of various percentage amounts are appropriate for stabilizing the heavy metals. Cation exchange capacity, selective ion electrode potentiometry and extraction experimental procedures were used in order to calculate stability values and determine free exchange cations of Pb and Cu. The fine fraction of waste combined with soil organics are stabilizing Pb and Cu meaning these will not be leaching out from the dumpsite if material is used as biocover.
