ABSTRACT

Foundries produce metal castings from ferrous or non-ferrous alloys and they operate in
various locations around the world. A typical foundry workplace is composed of
furnace area, pouring area, core making area, shaking out area and fettling area. The
manufacturing process involves the melting of metal into a liquid, the pouring of molten
metal into a cast, the removing of casting and the cleaning / finishing of the cast piece.
Dusts arise almost in every of these steps of foundry processes.
Solid waste streams from foundries are primarily used foundry sand, foundry dust
(collected by dry or wet electrostatic precipitators) or fabric filters, slag, scrap metal and
various other types of waste arising.
The main aim of this paper was to determine foundry dusts recyclability rate by their
addition into the sand mixtures.

Keywords: Foundry, Dust, Sand mixture, Waste, Cast iron, Recyclability rate
