The pie charts offer insights into the waste disposal of different categories in a particular country between 1960 and 2011.
Most strikingly, the proportion of paper, textiles, and other rubbish disposed of declined throughout the period, while that of plastic, wood, metal, and food experienced an upward trend. In addition, the disposal of other things stayed fairly steady.
In 1960, a quarter of paper was discarded but in 2011 this percentage showed a moderate decrease by about a mere 10% to 15%. Likewise, the figure for textiles had a minor drop from 17% to 11% during the same time period. Additionally, the proportion of other garbage disposed of made up 12% in 1960, and then fell substantially to 4% in 2011.
When it came to the remaining categories of garbage, there was an approximate 10% growth in the percentage of food and plastic waste to 21% and 18% respectively. Besides, consumers threw out twice as much wood 51 years after 1960, while the amount of mental only increased by 1% during the same period. On the other hand, glass, and green garbage disposal rates all stayed fairly consistent from 1960 to 2011 ( 5% for the former and 9% for the latter).
