Activated carbon - Wikipedia

Reactivation is the means by which spent carbon can be recycled and sold as new. Granular activated carbon (GAC) has an infinite reactivation characteristic, requiring just 10% make-up carbon to restore spent carbon to its original adsorptive capacity. Reactivated carbon offers a number of economic and environmental benefits:
