Scrap is a term used to describe recyclable materials left over from manufacturing and product consumption. It includes parts of vehicles, building supplies, and surplus materials. Often confused with waste, scrap in fact has significant monetary value.
Overall, the scrap industry processes more than 145,000,000 short tons (129,464,286 long tons; 131,541,787 t) of recyclable material each year into raw material feedstock for industrial manufacturing around the world. One example is scrap steel.
