materials (paper and cardboard, glass containers, aluminium cans, and plastics) in the US from 1982 to 2010.
Overall, paper and cardboard remained the most recycled material, while plastic had the lowest recycling figures throughout the period. Aluminium and glass both showed gradual increases.
At the beginning, paper and cardboard had a high recycling rate of about 65%, rising to a peak of 80% in 1994. However, after that, it slowly declined, ending at around 70% in 2010. Glass containers started at nearly 50% in 1982, dropped to 40% in 1990, but then recovered steadily to reach 60% by the end.
Aluminium cans were first recorded in 1986 at roughly 5%, but their recycling rate improved consistently, finishing at close to 45% in 2010. In contrast, plastics had the lowest percentage. They started at around 3% in 1990 and experienced only a slight rise to just 8% by 2010.
In summary, while all materials except plastics showed improvement, paper and cardboard were consistently the most recycled items over the years.
