Phytomining could be an alternative technology for the recovery of valuable metals from secondary sources, such as waste incineration bottom ash. The aim of this work is to recover strategic metals from waste incineration bottom ash using metal accumulating and hyperaccumulating plants. Our work is targeting critical raw materials defined by the European Commission in 2014. The target metal species in our project are amongst others gallium, antimony, cobalt, 4 molybdenum, manganese, copper, zinc, vanadium, chromium, nickel and selected rare earth elements. Five plant species (Brassica napus, B. juncea, two different clones of Nicotiana tabacum, Sedum plumbizincicola, and Alyssum pintodasilvae) are currently being tested for potential accumulation of these metals from a mixture of waste incineration bottom ash, residues from mechanical biological waste treatment and biochar.
