The table provided illustrates the quantity of waste produced in six disparate locations, namely Ireland, Japan, Korea, Poland, Portugal, and the US over a twenty-year-hiatus. From an overall perspective, it is apparent that there were unknown figures in Ireland and Korea, whereas, the other countries possessed completed data in the past two decades.
Looking at the picture in more detail, we can observe that there were missing amounts of waste in both Ireland and Korea. In 1980, the amount of waste in Ireland stood at 0.6 million tons, which was the lowest figure among the 6 countries. Yet, there were no sufficient figures in 1990. What's more, Ireland generated almost 10 times the waste, 5 million tonnes to be specific, compared to 1980. In terms of Korea, it had no data related to waste production in 1980. Subsequently, in 1990, Korea made 31 million tons of waste, which was slightly less than Japan. 10 years afterwards, waste production in Korea plummeted from 31 million tons to 19 million tons.
In stark contrast, the other four countries had complete figures pertinent to waste production. First of all, in 1980, Japan created 28 million tons of waste. Despite it being the second biggest amount of waste production between the 5 countries, it was significantly less than the US, 103 million tons in specific. Following a high growth rate, Japan generated 32 million tons and 53 million tons of waste in 1990 and 2000 respectively. Secondly, notwithstanding that Poland and Portugal experienced an overall increase in the amount of waste during 1980 and 2000, the amount of waste production was considerably less than other countries. Last but not least, the US generated the largest amount of waste among the 6 countries from 1980 to 2000. Moreover, the amount of waste also underwent a whole time increase simultaneously.
