Different type of waste recycled

The bar chart compares the recycling rates of four different kinds of waste material (plastic, cans, paper, and glass) in a city, from 1992 to 2002.

It is clear that the percentage of all types of recycled waste generally increased over the period. While glass was the most recycled waste material, the opposite was true for plastic during the majority of the period.

Paper and glass were the two most recycled types of waste material during most of the period. Beginning at approximately 14% and 15% respectively, both figures rose considerably to 21% and 29% five years later. By the end of the period, the recycling rates of paper and glass were almost double that of plastic and cans, at approximately 40% and 50%.

Plastic and cans were recycled far less, with the figures beginning at around 10% and 18% respectively, in 1992. While the figure for plastic slightly increased by about 2% in 1997, the figure for cans dropped by about half. In 2002, the figure for recycled plastic remained the same, however, the amount of cans recycled jumped back up to around 20%.
