The bar chart illustrates the incidence of recycling of four kinds of common materials discarded by a city’s domestic residents at three equal intervals in the decade starting with 1992. The initial, 1992, recycling rate of all the four is roughly equal. The trend thenceforward is almost universally one of continued increase, with the final figures being higher by anything from a meager few percentage points for plastic to triple the starting number for glass.
A more detailed analysis shows the beginning of the researched period with 10% of plastic refuse being recycled by households vs. 17% for aluminum cans. Paper and glass were almost level at about 15%. Five years later, in 1997, the foregoing figures went up in all the cases bar cans, which actually dropped 5%, to 12%. Plastic was recycled a smidge more than a half a decade prior (up 2% to 12%) but the incline was far more pronounced with paper and glass, which roughly doubled from their starting line of 15%: 32% for the former and to 28% for the latter.
At the end of the period, another five years later, plastic was still being recycled the least (12%, just as in 1997) but the other three substances increased. Just under a fourth of cans were now recycled (24%, approximately double the 1997 figure) as well as every two out of five cans (38%) and almost a half reusable glass (48%).
