The given table gives information about the amount of waste output in six countries over a twenty-year period: in 1980, 1990, and 2000.
Overall, it is clear that the US had the largest amount of waste production in three given periods, increasing significantly decade by decade. In contrast, Ireland reported the smallest quantity of waste over the decade. The other countries experienced some fluctuations over the twenty-year period.
Looking at the table clearly, the US produced the highest amount of waste, starting the period at 131 million tonnes, and increased considerably to 151 in 10 decade. The figure then reached 192 million tonnes in 2000, which was its peak level. As for Japan, waste production stood at 28 million tonnes in 1980, the figure then climbed by 4 million tonnes in 1990. Waste production increased by more than 20 million tonnes, reaching roughly 53 million tonnes in 2000.
Turning to the other countries, the waste production was 0.6 million tonnes in 1980 in Ireland. Although there was no waste output in 1990, waste production increased to 5 million tonnes. In Korea, any waste production was not observed in 1980, despite showing a considerable growth to 31 million tonnes in 1990. The figure, however, declined to 19 tonnes. A similar trend was observed in Poland and Portugal, where the waste production was 4 million tonnes and 2 million tonnes, respectively. By 2000, the figure reached 6.6 million tonnes and 5 million tonnes, respectively.
