The most usual way of recycling graphite occurs when synthetic graphite electrodes are lathe turnings are discarded, or the electrode (or other) to the electrode holder. A new electrode replaces the old one, but a sizeable piece of the old electrode remains. This is crushed and sized, and the resulting graphite powder is mostly used to increase the carbon content of molten steel. Graphite can a heat resistant but often not recycling because of their graphite
