The given pie charts illustrate the distribution of hazardous materials in three different countries.
Overall, there are harmful products which are divided into five categories (recycling, incineration, underground, chemical treatment, and dumping at sea). However, not all of them exist in all countries. In the Republic of Korea, recycling garbage dominates, whereas underground rubbish is the largest category in Sweden and the United Kingdom.
Looking at the details, the Republic of Korea and Sweden are categorized into three groups; incineration in both countries is the lowest at 9% and 20%. The percentage of recycling accounts for around seven in ten, more precisely at 69 percent in the Republic of Korea. In Sweden, this figure represents a quarter, and the last is underground waste which constitutes 22% and 55%.
As for the United Kingdom, all five categories exist. The amount of chemical treatment and dumping at sea makes up the same share, at 8%. The quantity of landfill waste represents the majority, over three quarters, at 82 percent. Finally, the lowest is the burning of waste at just 2%.
