The line chart provides percentages of recycling for four different materials in an unnamed country from 1982 to 2010. It can be observed that all four materials’ recycled percentages have been increased in the end. Although, some had steadily increased, but some had fluctuated.
Proportion of recycled paper and cardboards grew slightly to its peak around 70% between 1982 and 1986, but than sunk to its initial value of 65% in the year 1990. After its sudden spike to in 1994, the percentage decreased steadily until 2010 to an amount of 70%. On the other hand, recycling rate of glass containers declined to their minimum value of percent. After this decline, the value rose gradually, and eventually passed its initial value of percent and reached a rate of 60% in 2010.
Of the other materials, alumininium cans had the greatest growth in recycling rates overall. After its introduction in 1986, its recycling rate was only 5%, but by the year 2002 one quarter of all aluminium cans in the country was being recycled. Beyond that point, recycling rates grew even farther, until a value of 45% in 2010. However, Plastics, which have been introduced in 1990, were recycled by only around 3% in 1990, and the situation improved only slightly until 2010, to a value around 9%.
