The bar chart gives information about the number of waste that were collected by a recycling organization over a period of 5 years, starting from 2011 to 2015.
Looking from an overall perspective, it is readily apparent that while this center collected paper the most, the opposite was true for the number of waste in gardens.
In 2011, there were 57 tons of paper collected and this figure witnessed a slight decrease in the next 4 years, but finally, in 2015, 70 tons were gathered by this company. In contrast, only 32 tons of waste were collected in the gardens in 2011 and this amount experienced a noticeable fall by 17 tons in 2012, after rising to 35 tons at the end of the period.
The second position relating to the amount of waste belonged to glass with 48 tons at the beginning of the period, and declined by 7 tons in 2012, before increasing gradually to over 50 tons, exactly 52 tons of glass collected. Besides, the recycling center stored about 35 tons of tins in 2011, and went up to 39 tons 4 years later, after having a reduction to only 27 tons in 2012.
