Materials handled can include <br />broken or used castings, pistons, transmissions, siding and <br />punching blanks and other similar aluminum-containing pieces. <br />The scrap is charged to an aluminum sweat furnace designed to <br />heat the parts to a high enough temperature to melt only the <br />aluminum, which flows into a separate chamber from which, it can <br />be poured into molds. The remaining metals are removed as solids <br />for recycling. Oil and grease fumes from heating the charge pass <br />through an afterburner before discharge to the atmosphere. <br /> <br />II.
