The bar chart illustrates changes in the rates of three different recycled home trash, including plastic, cans, paper, and glass, in a particular urban area, spanning from 1992 to 2002. Overall, plastic was the least recyclable material, while the reverse was true for glass. Remarkably, the recycling culture in this city had been effectively fostered throughout the documented period, with an absolute upward trend witnessed in all categories.
Regarding the sorts of household garbage that were prevalently recycled, glass emerged as the most reusable source, as it showcased a notable trajectory, surging from roughly 17% in 1992 to 48% by the end of the survey. Initially about 8% higher than the former, plastic, on the other hand, exhibited a steadier increasing pattern, growing to 31% in the middle phase before climbing by 8% by 2002.
Turning to the remaining materials, which were obviously less eco-friendly than glass and paper due to their minor figures, the proportion of cans converted into applicable stuff, though was more substantial than plastic, displayed a relatively erratic rising trend, with a decrease of a whopping 5% from the initial 18% recorded in 1997, eventually rebounding again to reach the height of 33%. Meanwhile, the non-recyclability of plastic was signified as its data reveals a marginal growth of 1% from10% in the first year of the report before becoming stagnant at this low until the final year of 2002.
