The pie charts compare the proportions of nine different disposed wastes in one specific country in 1960 and 2011.
Overall, it is apparent from the charts that paper and food contributed the highest figures in both years. In addition, plastic, wood and food waste increased considerably in the timeframe, while paper, textile and other waste disposals followed the reverse pattern and rest of disposed wastes remained unchanged.
In 1960, one quarter of all disposed waste was paper which decreased to 15% in 2011. This number followed by textile waste with 17% in 1960 and dropped by 6% in the latter year. On a similar way, 12% of other disposed waste trailed behind in the beginning which saw merely 4% in 2011. The proportions of green waste, metal and glass did not change over the period, accounted 9% and 5% respectively.
However, the rest of garbage increased over the years. By 2011, the plastic waste had become the second biggest source of disposed waste, at 18%, more than double its 1960 figure (8%). Concurrently, wooden waste had doubled to 8%, whereas food waste also increased significantly to 21%, making up the highest percentage of disposed waste in the latter year.
