Moreover, food and other were both 12% in 1960, and after a period of fifty-one years, the dramatic rise was true for food by 9% to 21%, while other’s figure decreased by three percentage points.
In 1960, plastic waste disposal accounted for only 8%, while, in 2011, it increased significantly to 18% and was ranked in second place. Furthermore, the wood, which had the smallest proportion for only 4% in 1960, doubled and became 8% in 2011.
