The three pie charts illustrate the different methods of waste disposal in the Republic of Korea, Sweden, and the United Kingdom. The methods include recycling, incineration (destroying waste by fire), underground disposal, chemical treatment, and dumping at sea.
In the Republic of Korea, recycling is the predominant method, accounting for 69% of waste disposal. This is followed by underground disposal at 22%, and incineration at 9%. No waste is treated chemically or dumped at sea in this country.
Sweden, on the other hand, prefers underground disposal, which constitutes 55% of its waste management. Recycling is also significant at 25%, while incineration handles 20% of the waste. Similar to Korea, Sweden does not use chemical treatment or sea dumping for waste disposal.
The United Kingdom shows a different trend, with the majority of waste, 82%, being disposed of underground. Incineration accounts for 8%, while recycling and chemical treatment both handle 8% of waste each. The UK is the only country among the three that uses all five methods, including 2% of waste being dumped at sea.
In summary, while the Republic of Korea and Sweden primarily focus on recycling and underground disposal respectively, the United Kingdom relies heavily on underground disposal but also utilizes a variety of other methods.
