Waste Disposal Method, destroying dangerous waste products - Pie charts

The pie charts below show how dangerous waste products are dealt with in three countries.

The pie charts compare the amount of harmful waste products managed using 5 different methods, namely recycling, incineration, underground, chemical treatment and dumping at sea in three countries.

It is clear that there are only three ways used to deal with dangerous useless products in South Korea and Sweden, while harmful waste output in the UK is managed by using 4 different types of methods. The proportion of those products managed using underground waste disposal method in the UK is the highest number in all three countries.

In the UK, the largest proportion of dangerous waste products, 82% is managed by underground solution. Also, over half of those products are dealt with by using the same way in Sweden, compared to only 22% of those waste output in South Korea. On the other hand, recycling solution contributes to over two-thirds of South Korea's dangerous waste management methods, while there is only 25% of those waste output is recycled in Sweden.

The least common form of destroying dangerous waste products is using fire in South Korea, Sweden and the UK, about 9%, 20%, 22% of those products respectively. The figures for the UK's dangerous waste output are managed by using chemical treatment and dumping at sea are about 8% each.

It is clear that there are only three ways used to deal with dangerous useless products in South Korea and Sweden, while harmful waste output in the UK is managed by using 4 different types of methods. The proportion of those products managed using underground waste disposal method in the UK is the highest number in among the three countries.

The pie charts compare different types of waste management in three countries, the Republic of Korea, Sweden and the United Kingdom.
Small numbers, such as those less than ten, should be spelled out. For example: "three" or "five" instead of 3 or 5.


You should select the most significant features to mention in the overview paragraph. Here is my example:
It is clear that landfill disposal and incineration are used in all three countries. While waste burial accounts for the highest proportion of waste disposal in two European countries, recycling is the main method of dealing with waste in Korea.

It is not stated which part of Korea is using that particular method of waste disposal, so I think it is better to stick to the given information which is Korea as a whole or Republic of Korea. I think you just need to restructure your paragraphs and sentences. Overall, it is good.
