The given line graph illustrates information about recycled rate of four materials- paper and cardboard,glass containers,alumininium cans, and plastics from 1982 to 2010.Overall,it can be observed that the paper and cardboard had by far the highest recycling rates,throughout the period,despite a gradual decline after the mid-1990.In contrast,plastics remained the least recycled material,showing only a slight increase.Glass containers fell initially,but the recovered steadily,while the alumininium cans experienced the most dramatic growth.
Paper and cardboard recycling rose from about 65% in 1982 to a peak of roughly 80% in 1994. After that, the figure declined gradually, ending at around 70% in 2010. Glass containers started at approximately 50% in 1982, dropped to about 40% by 1990, and then climbed consistently to reach 60% by the end of the period.
Aluminium cans showed a sharp upward trend, increasing from only about 5% in 1986 to around 45% in 2010, indicating a significant improvement in recycling efforts. By comparison, plastics rose slowly from roughly 2-3% in 1990 to just under 10% in 2010, remaining far below the other materials.
In summary, while recycling rates improved for most materials, paper remained dominant and plastics lagged considerably behind.
