The graph provides data on the recycling percentages of four types of materials — paper and cardboard, glass containers, aluminium cans, and plastics — in a specific country from 1982 to 2010.
Overall, the recycling rate of paper and cardboard remained the highest throughout the period, despite a slight downward trend after peaking in the mid-1990s. Plastics, by contrast, consistently had the lowest figures, showing only marginal growth over nearly three decades.
In detail, paper and cardboard recycling stood at approximately 65% in 1982, reached its zenith at 80% by 1994, and then experienced a gradual decline, falling to about 70% by 2010. Glass containers exhibited a moderate but steady rise, increasing from around 50% in the early 1980s to just above 60% at the end of the period, despite a minor dip in the early 1990s.
Aluminium cans, which were not recorded until 1986, showed the most consistent upward trajectory, climbing from roughly 10% to over 45% by 2010. Meanwhile, plastics remained the least recycled material, beginning at around 2% in 1990 and barely exceeding 8% by 2010, indicating limited progress.
In conclusion, although all materials displayed some level of improvement in recycling rates over the given timeframe, only aluminium cans demonstrated a consistently positive trend, while paper and cardboard, despite their dominant position, showed signs of decline. Plastics, notably, lagged significantly behind, highlighting a persistent challenge in their recycling.
