Leaching of Wood Ash

Bottom ashes from technical incineration processes are containing heavy metals and/or trace elements. Depending on the quality of wood and the incineration technology, the high concentrations of heavy metals can demand high costs of disposal.

 

Novis is currently developing a process, to lower heavy metal contents in incineration ashes from wood. In co-operation with the University of Tuebingen, the University of Applied sciences of Rottenburg and an industrial partner, a process is designed and evaluated, to lower heavy metal concentrations within these bottom ashes and to recover them as valuable metals fractions.

 

The project is named: "Trace elements in heat and power station side products"
