The given graph demonstrates the recycling rate for four various materials from 1982 to 2010 in the various countries.Overall, we can observe that aluminum cans rate increased sharply, but other materials percentage just made a few changes.
Firstly, we can indicate that paper, cardboard and glass containers appeared in 1982. The percentage of organic and glass materials was similar to each other. The blue graph has a fluctuation tendency since 1982. For the first 10 years it reached 70 percentage level, but returned to the old proportions. In the last 20 years the highest per cent was 80. After that, the level decreased steadily until 2010. In the first 8 years glass containers range fell down to 40 per cent, then since 1990 it started to raise slowly.
Secondly, the aluminum cans and plastics formed in 1986 and 1990. The green graph has a stable growth over all periods of time and reached about 45 per cent in the end.
On the other hand, plastic tendency has a very slow growth during a 20 year period.
