The column chart provides information about the amount of waste collected by a recycling center in the form of paper, glass, tins and garden waste, between 2011 and 2015. Overall, the presented waste categories exhibited varying degrees of collection during this period. However, as opposed to the previous years, waste collection figures for all types stood at the highest proportions in the last year. Of particular note is the fact that paper and glass comprised a larger share of the collected waste during the entire period.
The amounts of waste in the form of paper and glass were higher than those of other waste types. Paper, which initially decreased from 57 tons in 2011 to 40 tons in 2013, represented a sharp increase to 70 tons in the final year. Contrary to this dramatic fluctuation was the figure for glass which was more consistent, with the numbers oscillating at around 40-50 tons and eventually displaying the highest collection rate at 52 tons in 2015.
Similar trends were seen in the quantities of tin and garden refuse. While the amount of tin accumulated by the recycling center started the period with 35 tons, it dipped to 27 tons the following year. This was then followed by a period of stability at around 34 tons between 2013 and 2014, before rising to 39 tons to wrap the period. As for the least collected waste, which was garden litter, its figure halved from the initial 32 tons in 2012. Despite this, the number recovered in the year 2013 by reaching 31 tons again, followed by further increase to period-high 35 tons in 2015.
