The table compares the proportion of total quantity of waste in million tonnes(mt) produced among six various countries in 1988 and 2000.
In general, the figure shows that the amount of garage produced increased over the period, except for the Ireland, which showed downward trend. It is also notable that the amount of waste made in the United States showed the highest index among other countries across all the given years.
Starting with more noticeable changes, there were 15 mt in Japan in 1988, then had decreased by 1 mt in 1992, followed by jumped to 29 mt by the end of the span. Meanwhile the total of waste for the United States, starting from 1988, it was 107 mt, then had increased almost by 40 mt in 1992 and there was significant growth in its index, reaching 209 mt in the the end of the period.
On the other hand, the overall waste output for other four countries recorded less significant changes. Focusing on the Ireland, the amount of the waste was 10 mt in 1988, had started increasing by 6mt, then there was remarkable decrease to 9.9 mt in 2000. In contrast, the figures for all the remaining countries showed upward trajectories, yet at slower paces.Poland and Canada followed each other closely, with 10 mt and 20 mt respectively, in 1988.Then there was a decline in the amount of waste, reaching 2.89 mt (Poland) and 19 mt (Canada) in 1992, after which it rising to 18 mt and 29 mt in the end of span. Finally, for the Scotland, it was showed the low amount of the waste which is 3 mt in 1988 then had increased by 2 mt by end end of period and still was the less then other countries.
