The table gives information about produced waste in six various countries thoughout the period of 20 years (in millions of tonnes).
Overall, two countries, Poland and Portugal, show a balanced distribution of waste production, while the other four – Ireland, Japan, Korea and the US – exhibit significant disparities. Notably, the US had the largest gap, while Ireland the smallest.
Poland and Portugal a relative of equal share of produced waste. In Poland, between 1980 and 1990 the gap is only 1 millions of tonnes, with 4 tonnes and 5 tonnes and between 1990 and 2000 the gap is 1,6 millions of tonnes for each year. Conversely, in Portugal, waste production in 1980 (2 m.o.t.) and 1990 (3 m.o.t.) is slightly more prevalent than those in 2000 (5 m.o.t.).
The United States had the widest disparity, with 131 m.o.t. in 1980, 151 m.o.t. in 1990 and 192 m.o.t. in 2000. Japan follows with 28 in 1980, 32 in 1990 and 53 in 2000, making 15 of difference. Korea amounted 28 millions of tonnes in 1980, 31 millions of tonnes in 1990 and 19 millions of tonnes in 2000. Meanwhile, Ireland has the smallest gap – 2,4 between 1980 (0,6) and 1990 (3) and 2 between 1990 (3) and 2000 (5).
