The line graph illustrates the amount of recycling paper & cardboard, glass containers, aluminum cans and plastics materials in a certain country from 1982 to 2010.
Overall, we can see that the recycling rates for those four materials have changed over the 28-year period. While both Paper & cardboard consistently has the highest recycling rate, aluminum cans showed the most significant increase. Plastics remain the same throughout the years.
In 1982, only 10% of aluminum cans were recycled. However, over the next 30 years, the recycling rate of aluminum cans rose significantly to almost 50%. This surge may be attributed to the popularity of canned food during that time. While the glass containers have a decent start of 50% rate to 40% the first eight years. Then continuously grew to 60% in the next twenty years. Paper & cardboard had a 65% rate in 1982. Followed by a small rise to 70% and back to 65% in eight years. After that paper & cardboard had a massive soar of 15% in the year 1994. Plastics don’t seem to have a major increase nor decrease. In ten years period, it only expanded no more than 4%.
