The chart demonstrates the volume of four distinct waste categories processed at a recycling centre over a 5-year period from 2011 to 2015, measured in tons.
Broadly speaking, a salient feature of the data is that the figures for 4 types of recycled materials followed an overall upward trajectory. Markedly, paper waste consistently maintained its dominant position throughout the timeframe despite temporarily relinquishing its top spot to glass in 2013 before reaching an all-time peak in 2015. Furthermore, the remaining categories experienced a slight rise notwithstanding noticeable fluctuations.
Regardless recycled paper, it is evident that this recycled refuse registered the highest initial figure, with 57 tons of waste, hovering at nearly twice the level of garden waste. The figure for recycled paper subsequently dropped by around 7 tons, reaching 50 units in 2012. Returing to glass waste, which stood at the second position in 2011, then reducing to 41 tons in the following year. However, the figure for recycled paper was unexpectedly surpassed by that of recycled glass, 40 and 48 tons respectively. Paper reclaimed its dominance until 2015 in parallel with hitting the highest point of roughly 70 tons while the amount of glass waste only reached 54 tons.
Turning to the remaining categories, garden waste hovered around 32 tons while the figure for recycled tins outstripped it slightly with 35 tons. One year later, garden refuse slumped by over 50%, dropping from 32 to 15 tons of waste. In 2013, in stark contrast, both categories experienced a temporary rebound with 34 tons for tins waste and 31 tons for garden waste before witnessing a minor dip in the next year, 33 tons and 27 tons respectively. Over the end of the timeframe, a surge observed in recycled tins was recorded, hitting a peak with 39 tons compared to that of organic waste from garden (35 tons)
