The bar graph indicates how much waste was treated in three different procedures in a particular European country over a period of 4 years, starting from 2005.

Overall, the amount of waste disposal by landfills and dumping in the sea experienced a downward trend whereas that of burning remained unchanged between 2005 and 2008. It is also noticeable that the figure for burning was the highest of the three methods at this given time.

In 2005, the amount of garbage treatment by landfills, at 70 million tonnes, declined remarkably to 40 million tonnes in 2008. Likewise, there is a slight decrease in the figure for burning to 40 million tons in 2007 before soaring to approximately 65 million tons at the end of this duration, equal to the beginning.

With dumping in the sea method, the quantity of waste disposal fell slightly from about 55 million tons to 50 million tons in 2006 then stabilized in the following year. In 2008, the figure for dumping in the sea continued to decrease, equal to that of landfills, at 40 million tons.

The given bar chart compares and contrasts data on the changes in three different ways for discharging waste materials, measured in million tonnes in a country in European between 2005 and 2008.

Overall, the amount of garbage dumped in landfills and the sea witnessed a steady downward trend, while that burned fluctuated. It is also apparent that burning was the most popular process of waste disposal in 2008. In 2005, 70 million tonnes of garbage were landfilled. This number was progressively reduced by 10 million tonnes per year to 40 million tonnes in 2008. Similarly, the amount of garbage discharged into the sea decreased from 55 million tonnes to 40 million tonnes at the end of the period.

It can be seen that in 2005, the amount of garbage burned was about 5 million tonnes.This number subsequently saw a significant drop to as low as 20 million. tonnes in 2007 before rising again to 65 million tonnes the following year.
