Fly Ash Materials Handled Flexicon Corporation. In the past fly ash was released into the atmosphere, but local and regional pollution control standards now require that it is captured prior to release, usually by either mechanical or electrostatic separators. The collected fly ash is stored in silos for later disposal or beneficial re-uses.
