The line graph exhibits the portion of four different materials: paper and cardboard, glass containers, aluminum cans, and plastics; that were recycled between 1982 and 2010 in a country.
Overall, it is evident that paper and cardboard were the most recycled materials throughout the given period of time. Conversely, plastic materials were the least recycled objects.
To begin with, paper and cardboard were fluctuating from 1982 to the mid 1980s, reaching around 65%. Afterwards, in the mid 1990s, these materials peaked at approximately 80%. Nevertheless, from the mid 1990s to the late 2000s, they declined gradually to around 70%. In contrast, glass containers dropped from about 50% to around 40% by the mid 1980s. However, their recycling rate grew gradually to 60% by the late 2000s.
In contrast, plastic’s recycling rate remained almost unchanged, growing from approximately 5% to around 9% from the mid 1980s to the mid 2000s. Nonetheless, aluminum cans increased significantly from the mid 1980s to the late 2000s, arising from somewhere around 4% to approximately 46%.
