The bar chart illustrates proportions of four types of waste being recycled in a town from 2000 to 2010.
Overall, the percentage of four kinds of recycled waste represented an increasing trend from 2000 to 2010. The metal being recycled accounted for the most significant sector during the decade, with plastic in the least.
Looking into more details, the percentage of cans topped the list at around 13% in 2000 and decreased to 11% in 2005, which was the lowest proportion among all waste, before climbing to the second largest proportion of waste recycled (approximate 34%) in 2010.
Also noteworthy is the plastic, which stayed constantly at the least rate across the decade among four waste categories (respectively 12% in 2000 and 25% in 2010) expect it in the 2005.
In terms of paper and metal, they all kept continuously growing between 2000 and 2010. Compared with the increment, that of metal was larger than that of paper during this decade. The most remarkable point is that the percentage of metal went up to the most significant part in 2010 at 40% from around 11% in 2000, which was similar to the proportion of paper being recycled in 2000.
