The chart illustrates information about how much family trash of various kinds was recycled in one city over a ten-year period between 1992 and 2002.
It is obvious that there were upward trends in the percentage of different types of family rubbish recycled during the given period. Additionally, paper and glass were the most recycled types of waste.
In 1992, there were around 18% of cans which were converted into new materials and it was the largest number of recycled trash in four kinds, followed by glass, occupying roughly 15%. While the former witnessed a slight decrease before rising unsignificantly, the latter soared to 50% over the next ten years. This meant that the figure was the peak percentage of household garbage during the whole period.
The proportion of plastic converted into new materials started at 10% at the beginning of the period. Having increase minimally to approximately 12% in 1997, the figure experienced a stability until 2002. Meanwhile, there were only 14% of paper recycled in 1992, but then it more than doubled to almost 32% in 1997. After ten years, there was a marginal growth to 40% at the end of the period.
