We are pleased to announce the publication of the latest research paper in Waste Management, which deals with the material flows of heavy metals in the treatment of municipal solid waste incineration (MSWI) slag.
The study, conducted by  Simon Mika (Hofer), Julia Mühl, Stefan Skutan, Andreas Limbeck, Jakob Lederer and Philipp Aschenbrenner, evaluates an innovative dry-wet IBA treatment plant in Austria. 
The most important results are:
Improved treatment processes can significantly improve recovery rates:
Wet processes achieved a 52% separation of heavy metals from grate incineration (G-IBA).
In the case of fluidized bed incineration (FB-IBA), a separation of 28% was achieved with wet processes and a remarkable 57% with dry processes.
The study highlights the effectiveness of gravity separation in conserving metal resources and reducing the heavy metal content in the residual mineral fractions, creating pathways for more sustainable recycling processes.
