The recovery, or recycling, of paper and paperboard has increased from 34% of supply in 1990 to 67% of supply in 2015. Most of this recovered paper is consumed in the United States, but some is exported. Based on data from the American Forest and Paper Association, domestic consumption of recovered paper at U.S. mills increased to 31 million tons in 2015, while net recovered paper exports increased to 21 million tons.
