The given infographic depicts the amounts of paper, glass, tins and garden waste collected by a recycling centre, which are measured in tons over a four-year period, commencing from 2011.
Overall, the amounts of paper and glass always recorded the highest amounts collected throughout the period. Additionally, the figure for glass surpassed that for paper in the year 2013. By contrast, garden had the lowest and displayed a highly variable pattern among the categories, whereas tins remained comparatively stable.
Initially, paper stood at 57 tons of waste in 2011, which quickly slipped to 40 tons in 2013 and then recovered to 51 tons in the following year. This amount rose gradually and reached 70 tons at the end of the period, being the highest figure among the materials. Nevertheless, 48 tons of glass waste were delivered to the recycling centre in 2011, after which it experienced a downward trend to 41 tons in 2012. Followed by fluctuations over the remaining three years, the figure for glass then ended at 52 tons in 2015.
The remaining two materials were collected in lower quantities. Certainly, the recycling centre received 32 tons of garden waste at first, before a significant plummet to 15 tons in 2012. However, this volume of waste climbed back to 31 tons next year, then accompanied by an irregular trend and finished at 35 tons in 2015. Tins, conversely, witnessed a narrow pattern. The amount of tin waste brought to the recycling centre at the beginning was 35 tons, then dropped marginally to 27 tons and rebounded to nearly its starting point (which was 34 tons in 2013). After that, the quantity of waste eased slightly and increased rapidly again to 35 tons in 2015.
