The bar chart illustrates the percentages of various types of household waste that were recycled in one city between 1992 and 2002.
The bar chart provides information about the recycling rates of household waste, such as glass, paper, cans, and plastic, (given in percentages) in a particular city over the period from 1992 to 2002.
Overall, glass and paper were recycled at significantly higher rates compared to the others throughout the period. While the recycling rate of glass increased dramatically from the lowest to the highest and eventually surpassed paper, the rate for paper rose initially before being overtaken. By contrast, plastic and cans remained at much lower levels, although cans experienced some steady growth.
Initially, in 1992, the proportion for glass and paper were the same at around 14%. Plastic stood at about 10%, while cans were the highest, at roughly 18%. Subsequently, by 1997, the percentages for both glass and paper rose substantially, reaching nearly 30% for glass and approximately 32% for paper. In contrast, plastic experienced only a slight increase to around 12%, whereas the rate for cans declined to around 13%.
Finally, by 2002, the proportions for glass and paper continued to grow, dominating the chart. The percentage for glass surged ahead, overtaking paper and reaching close to 50%, while paper climbed to approximately 40%. Plastic remained largely stable at around 12%, whereas the rate for cans rose noticeably and increased to approximately 22%.
