Thermal treatment of metal-enriched biomass produced from heavy metal phytoextraction

Christian Ludwig, Catherine Keller

Phytoextraction is an environmentally sound method for cleaning up sites that are contaminated with toxic heavy metals. However, the method has been questioned because it produces a biomass-rich secondary waste containing the extracted metals. Therefore, f ...
