* Cadmium, using willow ( Salix viminalis ): In 1999, one research experiment performed by Maria Greger and Tommy Landberg suggested willow has a significant potential as a phytoextractor of Cadmium ( Cd ), Zinc ( Zn ), and Copper ( Cu ), as willow has some specific characteristics like high transport capacity of heavy metals from root to shoot and huge amount of biomass production ; can be used also for production of bio energy in the biomass energy power plant.
