The bar chart illustrates the quantities of waste disposed of through three different methods: landfill, burning, and dumping at sea, between the years 2005 and 2008. The most notable trend is the significant decline in the amount of waste sent to landfills, while the quantities for both burning and dumping at sea remained relatively stable, with burning slightly increasing and dumping holding close to its previous levels. Specifically, the figures for burning and dumping at sea hovered around 400 tonnes and 600 tonnes, respectively.
The amount of waste sent to landfills experienced a steep decline, dropping from approximately 1.8 billion tonnes in 2005 to around 600 tonnes in 2008. In other words, the quantity of waste disposed of in landfills nearly halved over the three-year period.
Dumping at sea remained fairly constant at around 600 tonnes from 2005 to 2007 but saw a slight decrease to below 600 tonnes by 2008. In contrast, burning gradually increased from about 500 tonnes in 2005 to a peak of roughly 900 tonnes by 2008. Throughout this time, neither method of waste disposal—burning nor dumping at sea—reached 1,000 tonnes, nor did they drop to 400 tonnes.
