Is aluminum infinitely recyclable?

The atomic structure of aluminum, like that of other metals, allows repeated recycling without degradation or loss of inherent properties, though practical limits and contamination can restrict closed-loop reuse. 

All materials lose volume when recycled; once at a recycling facility, aluminum recycling has a metal recovery rate of 98%. However, gaps in the recycling chain before aluminum ever reaches a furnace reduce the recycling rate; globally, the rate for aluminum cans is 75%, and 43% in the United States. An estimated 75% of the primary aluminum ever produced is still in use today. 

Available data shows recycling uses up to 95% less energy than primary aluminum production, with a similar reduction in carbon emissions. Aluminum recycling now accounts for the majority of American aluminum production.
