The table provides data about the amount of waste manufactured (in millions of tonnes) over the period from 1980 to 2000, in six distinct countries.
Overall, it is readily apparent that U.S accounted for biggest numbers. It is clear that Ireland and Portugal made up smallest shares.
In 1980, U.S produced approximately 131 million tonnes of debris, following distantly behind was figure for Japan with 28 million tonnes. Poland comprised 4 million tonnes, while Portugal accounted for half of this (2 million tonnes). Others constituted negligible proportions, Ireland comprised 0.6 and figures for Korea were not available.
By 1990, figures increased in mix. The amount of litter produced in USA rose to 151 tonnes, whereas two south-Asian countries demonstrated nearly same rates with Japan (32 million tonnes) and Korea (31 million tonnes). Poland and Portugal showed gradual increased to 5 tonnes and 3 tonnes. Figures for Ireland were not given this year.
In contrast in 2020, volume of waste produced in U.S. escalate to the 192 million tonnes nearly four times more than Japan manufactured (53 million tonnes). Korea broke the trend by decreasing the quantity of rubbish generated to 19 million tonnes. Poland accounted for 6.6 tonnes, while Portugal and Ireland demonstrated similar numbers 5 million tonnes.
