Combustion ash under high voltage

As the study "High voltage selective fragmentation on Swedish mineral fraction of incineration bottom ash (MIBA)" by scientists from Sweden and Switzerland shows, high-voltage fragmenta-tion opens up new perspectives for the recovery of metals from waste incineration ash. Addi-tional metal contents of up to 2.2 percent could be tapped, while at the same time new, more homogeneous material flows were created. However, regulatory limits and material challenges have so far slowed down industrial implementation. The study was published in "Waste Ma-nagement".
