The bar graph compares how much waste was treated by different methods of disposal practices in one European nation across a quadrennium, commencing in 2005.
What is most striking when looking at the data is that incineration showed the most pronounced volatility, escalating from an already high treatment level in 2005 to become the leading disposal practice the end of the period. It is also important to note that, there was a clear shift away from landfill and dumping in the sea, primarily driven by decreases in the amount of waste disposed of using the two approaches.
Focusing first on landfill and sea dumping, the figures for both practices witnessed a severe downturn, making them less popular waste disposal methods. Although holding the top position in 2005 with 70 million tonnes of waste being sent to landfill, the figure declined gradually by 10 million tonnes every year before finishing at 40 million tonnes by the end of the period, which was nearly half the size of its initial quantity. Despite facing a less significant downward momentum, the volume of sea dumping waste was reduced from approximately 55 to 50 million tones over the first three surveyed years, reaching the same waste level as landfill’s corresponding figure. In 2008, its volume of treated waste continued to be identical to that of landfill, simultaneously being lagged behind the leading approach (incineration).
Bucking the consistent trend, incineration demonstrated more considerable fluctuations. Burning diverged from the downward trend seen elsewhere as only there did the figure edge down between 2005 and 2007, before mounting a notable recovery a year later. In the first three given years, a substantial drop cut the figure from roughly 65 to just 40 million tonnes, reaching parity with the ending point of its counterparts. The period of low treated waste, nevertheless, was not to last as a rapid recovery allowed the figure to revisit its earlier peak, at about 65 million tonnes, placing it as the most widely adopted waste disposal practice on the chart in 2008.
