The pie charts demonstrate the data on the variety of discarded waste in an unnamed country in two separate years: 1960 and 2011.
Overall, it can be seen that nearly a half of waste increased over the period in question, while paper, textile and other undefined garbage only dropped throughout the years. It is also notable that while paper, food and plastic experienced the most significant changes, the proportion of green waste and glass remaind the same in both years.
Regarding to the types of waste which experienced the most dramatic changes in disposal, food, comprising only 12% of all disposed waste in 1960, had grown and had been set at 21% by 2011. Likewise, plastic constituted under one-tenth in 1960 (8%) and had increased to just over one-fifth (21%) by 2011. Paper waste, however, accounting for one-quarter of waste in 1960, had dicreased by 2011 to the value of 15%.
By contrast, textiles and other unspecified waste has shown less significant changes, reducing since 1960 by only 6% and 8% accordingly. Waste of wood, on the other hand, made up 4% in 1960 and had increased by also 4% by 2011. Metal waste had increased similarly by 2011, but only by 1%, having a value of 8% in 1960. Two other categories, namely green waste and glass, experienced no changes over the years and remained stable at 9% and 5%.
