Aluminum recovery from scrap (recycling) has become an important component of the aluminum industry. A common practice since the early 1900s, aluminum recycling is not new. It was, however, a low-profile activity until the late 1960s when recycling of aluminum beverage cans finally vaulted recycling into the public consciousness.
