The bar chart illustrates the percentages of total waste disposed of through four different methods in four cities (Toronto, Madrid, Kuala Lumpur and Amman). Overall, landfill has the largest percentage of waste disposed of in Toronto and in Amman, whereas incineration is the method that is used to dispose of most waste in Madrid and in Kuala Lumpur. Meanwhile, composting accounts for the smallest proportion of waste disposed of across all four cities.
Looking first at Toronto and Amman, it is evident that both countries have the same pattern, with landfill accounting for the highest percentage, at around 74% and at about 49%, respectively. The figure for incineration in Amman is far higher than that in Toronto, standing at approximately 38% and at nearly 11%, in the same order. This is followed by recycling in Amman (around 11%) and in Toronto (roughly 8%), while composting records the lowest figure, at about 7% and at nearly 2% each.
Turning to Kuala Lumpur and Madrid, we can see a slightly different pattern, in which incineration has the greatest proportion at around 55% and at about 40%, respectively. Recycling comes next, standing at the same figure at approximately 23%. In contrast, the figures for landfill and for composting in Madrid are higher than those in Kuala Lumpur, where the former records around 29% and about 9% each; the latter stands at approximately 16% and at roughly 7%, in the same order.
