The given infographic depicts the quantities waste of paper, glass, tins and garden gathered by a recycling centre, which is measured by tons over a course of 4 years, commencing from 2011.
Overall, the amount of paper along with glass always contributed to the most wasted materials throughout the period. Additionally, glass was the only figure which surpassed paper in the year 2013. By contrast, garden had the lowest and the most unstable data among the categories, while the opposite trend was witnessed in tins.
Initially, 57 tons of paper was collected in 2011, which suddenly slipped to 40 tons in 2013 and then recovered to 51 tons in the following year. This data continuously rose sharply and reached 70 tons at the end of the period, being the highest figure among the materials. Nevertheless, the amount of glass began at 48 tons, after which it experienced a downward trend to 41 tons in 2012. Followed by a fluctuation through 3 years, the figure of glass ended at 52 tons in 2015.
The remaining of two materials was collected in lower quantities. Certainly, the garden gathered 32 tons of waste at first, before illustrating a significant plummet to 15 tons in 2012. However, this position climbed back to 31 tons next year, then accompanied by a volatile trend and finished at 35 tons in 2015. Tins, conversely, witnessed a narrow pattern, which began at 35 tons, then dropped marginally to 27 tons and rebounded to nearly its starting point (which was 34 tons in 2013). After that, the position of tins eased slightly and increased rapidly again to 35 tons in 2015.
