The pie charts illustrate the proportions of waste disposal in nine categories in one country in 1960 and 2011. Overall, while food and plastic waste experienced significant increases, paper and textiles saw the most notable declines. Other categories, such as glass and green waste, remained relatively stable over the period.
In 1960, paper accounted for the largest share of waste disposal at 25%, but this figure dropped sharply to 15% in 2011. Similarly, textiles, which made up 17% of the total waste in 1960, fell to 11% by 2011. The category labeled “other” experienced the most dramatic decline, plummeting from 12% to just 4% over the same period.
In contrast, food waste rose significantly from 12% in 1960 to 21% in 2011, becoming the largest category in the latter year. Plastic waste also saw a substantial increase, growing from 8% to 18%. Meanwhile, wood and metal experienced slight increases, both rising by less than 5%.
Finally, the proportions of glass and green waste remained relatively unchanged. Glass accounted for 5% in both years, while green waste maintained a steady 9%. These categories exhibited minimal variation compared to others.
