Band 6+: The charts below give information about different types of waste disposed of in one country in 1960 and 2011. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The given double pie charts compare and contrast the categories of the percentages of waste disposed of across different retail sectors in one country in the period of time from 1960 to 2011.

It is clearly seen from the charts that, there was a downward trend in paper, metal and textilies, while the opposite was true for plastics, wood, food and other types of waste.

According to the charts, in the 1960s paper dominated as the highest proportion of waste disposed of at 25%, which was 21% more than that of the lowest segment, wood. Plastis and food comprised 17% and 12% respectively. In addition, the others accounted for the lower figures, fluctuating between 5% and 9% throughout the 1960s.

Looking into the charts, there was a significant increase in food to 21% compared to 1960, and became the highest level of waste disposed of in 2011. Also, plastis climbed considerably about 10% and became the second highest proportion. By contrast, paper had decreased dramatically for 51 years and remained at the third place. Besides, while metal and wood rose slightly, the others all declined or stayed stable.
