The pie charts illustrate many types of waste disposal, namely food, paper, green waste, metal, glass, plastic, wood, textiles, and other, in one country from 1960 to 2011.
Overall, the figure for waste disposal fluctuated throughout the period. While textiles, plastic, wood, and other experienced an upward trend, the figure for paper waste did the opposite. Notably, glass and green waste remained unchanged after 51 years.
In 1960, paper was the dominant waste, representing a quarter of the pie chart total at 25%. Afterward, this figure decreased significantly to 15% and no longer held the first position. Textiles, with 17% in 1960, then decreased slightly to 11%. Food and other waste had the same shares, each contributing 12%. However, while other waste dropped further to 4%, the figure for food waste showed a considerable increase of 9%, becoming the highest waste disposal in 2011.
Meanwhile, plastic trash was allocated only 8% in 1960; it rose dramatically to 18% by 2011. Metal exhibited 8% and inched upward to 9% from 1960 to 2011. In contrast, both glass and green waste remained stable at 5% and 9%, respectively.
