Innovative recovery fo metals from waste incineration residues using hyperaccumulating plants
Abstract
Metal-hyperaccumulating plants are used to gain secondary metal resources from incineration slag, which is currently being landfilled in Austria. After a year of laboratory trials, where the substrate is analysed and condition for proper growth of a selection of hyperaccumulating plants, field trials are implemented to test the process under real life conditions. The harvested biomass, enriched with metals, is pre-treated in some cases to increase relative metal concentrations, and then it is subjected to standard metallurgic processes to gain the purified metals in Montanuniversity Leoben and Montanwerke Brixlegg. All processing steps are integrated into harmonized engineering procedure which allows an economic and environmental appraisal oh the innovative technologies in a concrete scenario. Close collaboration between private industry and research partners is integral to the whole project.
