Sixty nine percent of waste materials in Korea is being disposed of by means of recycling

The pie charts illustrate the 5 different types of waste disposal which are recycling, incineration, underground, chemical treatment and dumping at sea that the Republic of Korea, Sweden and the United Kingdom are applying.

Sixty nine percent of waste materials in Korea is being disposed of by means of recycling. While in Sweden and the UK, 55% and 82% of their garbage are being buried underground. Apparently, Korea and Sweden does not practice the process of disposing unwanted resources with the use of chemical treatment nor dumping at sea. However, it is upsetting to know that both of these countries destroy 9% and 20% of their rubbish through a process called incineration, respectively. It is also interesting to note, that although the UK mostly exercise underground burying of waste materials, it is also the only country among the three mentioned above that manages disposal of waste by treating it with harmful chemicals, dumping at sea and incinerates trash with the following percentages, 8%, 8% and 2%, correspondingly.

Please feel free to make any corrections. If you could mark it, that would be great!

do not instead of does not

revise this part of the sentence does not practice the process of disposing unwanted resources with the use of chemical treatment nor dumping at sea


consider keeping one word throughout the paragraph to refer to waste

I thought that it is good to use various terms so it would not sound redundant or repetitive.

I would say Korea and Sweden do not practice the process of disposing unwanted resources through chemical treatment or dumping at sea.
