Band 5+: The line graph depicts the proportion of four various materials (paper & cardboard, glass containers, aluminium cans, and plastics) were recycled from 1982 to 2010 in a country.

The line chart compares the recycling rate of four different items in a specific country throughout the period from 1982 to 2010.

Overall, it is clear from the graph, over the span of 28 years , there is slight growth in the proportion of reusable materials such as paper and cardboard , glass container, plastic ; however, the figure for aluminium cans grew dramatically.

In 1982, exactly 50% of glass containers and about 65% of paper and cardboard were recycled . Even though the figure for glass containers plunged to exactly 40% in 1990 , then after it never sank. Moreover , the percentage reached exactly 60% in 2010.The recycling rate of paper and cardboard grew to 60% in 2010 , before showing some fluctuations during 1986 to 1994.

The data of aluminium cans and plastics is not given for the first one year and first two years respectively. About 3% of plastic were reused in 1990, this proportion slightly surged by a mere of about 5% in 2010. In contrast, proportion of aluminium cans that were recycled was around 5% in 1986, and markedly escalated by 40% during the period from 1986 to 2010.
