Band 9: This graph shows the proportion of four different materials that were recycled from 1982 to 2010 in a particular country. Summarise the information by selecting and reporting the main features, making comparisons where relevant.

The line graph illustrates the recycling rates of four distinct materials in an unnamed country from 1982 to 2010.

Overall, the data indicate substantial growth in recycling rates for most materials, particularly aluminum cans, while plastics exhibited the least progress during the observed period.

In 1982, the recycling rates for paper and cardboard stood at approximately 20%, while glass containers accounted for 10%, aluminum cans merely 5%, and plastics had not yet commenced recycling efforts. Over the successive decades, a notable upward trend is observed, especially for paper and cardboard, which experienced a dramatic increase to 80% by 2010. Glass containers also saw a significant rise, reaching 50%, while aluminum cans demonstrated the most remarkable growth, surging to 70%. In contrast, plastics, which began from a baseline of 0%, only managed to achieve a recycling rate of 10% by the end of the period.

Examining the trends in detail reveals that the recycling rate for paper and cardboard peaked at 80% in 1994, before experiencing a slight decline to 70% in 2010. Conversely, glass containers progressed steadily, increasing gradually to a total of 50% by 2010 after a brief dip in 1990. Aluminum cans showcased the most consistent increase, starting from 5% in 1982 and escalating to 70% by 2010. Plastics exhibited the least improvement, with their recycling rates climbing slowly from 0% to just 10% over the same span, indicating stagnant growth compared to other materials.
