The two pie charts illustrate the proportions of various types of waste disposed of in a particular country in 1960 and 2011.
In 1960, paper accounted for the largest share of waste at 25%, followed by textiles 17% and food 12%.Other categories => [] [nên lược phần này và liệt kê rõ ra luôn] such as green waste 9%, metal 8% plastic 8%, glass 5%, and wood (4%) made up smaller proportions.The “Other” category => [] [lặp other 2 lần có thể gây khỏ hiểu] also comprised 12% of the total waste.
By 2011, the composition of waste had shifted significantly. Food became the most disposed item at 21%, while plastic rose sharply to 18%, overtaking paper, which declined to 15%. Textiles dropped to 11%, and “Other” waste decreased dramatically to just 4%. Green waste and metal remained stable at 9%, glass stayed at 5%, and wood increased to 8%.
Overall, the data shows a notable rise in food and plastic waste over the 51-year period, while paper and miscellaneous waste saw considerable declines. This suggests changing consumption patterns and material usage over time.
