In Sweden, incineration of household waste in waste-to-energy (WtE) plants is common, and generates around 250,000 metric tons (m.t.) of flyash every year. The rest of Europe accounts for around ten times that amount. Most of this waste is landfilled, but the ash often contains significant amounts of valuable metals, such as zinc.

The bottom dross formation represents 7–11% of zinc consumption during galvanizing. Galvanizers are not able to reprocess the dross in-house, therefore, it is sold at 65–75% of zinc price to recycling plants to produce high-quality zinc oxide or zinc dust (Worrell and Reuter 2014).The metal may be also separated from the dross and refined
