The pie charts give information about the ways of disposing of the hazardous waste in three countries.
Overall, underground disposal was the most common in the UK and Sweden, while recycling accounted for the largest proportion of hazardous waste in South Korea. Another noteworthy fact is that chemical treatment and dumping at sea was only present in the UK.
Starting with the UK, over three-quarters of its waste was buried underground, compared with 55% in Sweden. As for incineration, it constituted a negligible two percent for the former, whereas for the latter it accounted for 20%, five percentage point lower than recycling rates in the same country. By contrast, the only country to use chemical treatment and dumping at sea was the UK, with each method accounting for eight percent.
The remaining country used recycling as the main mean of dealing with the dangerous waste products, with 69% of them recycled. The lower figures can be observed in underground burial, showing 22%, three times lower than that by recycling. As regards incineration, the republic of Korea burned nine percent of its hazardous waste, making this method the least common across the country.
