The graph shows the percentage of recycling and the amount of total waste recovery in million tons per year in the United States between 1960 and 2005. Overall, there has been a gradual rise in the amount of total recovery of waste materials during the period, while the percentage of recycling has fluctuated slightly. The figure for total waste recovery was about 15 million tons per year in 1960 and during 45 years it increased to 80 million tons per year. Between 1960 and 1990, the amount of total waste recovery almost remained unchanged. The figure rose sharply by 40 million tons from 1990 to 1995. The proportion of recycling waste materials rose significatly during 1960-1990 years and reached a peak at 40 per cent twice: in 1990 and in 2005. There was a slight fall by 10 per cent from 1990 to 1995, but then figure has risen steadily until 2005.
