The graph below shows the amounts of waste produced by three companies over a period of 15 years.
The illustration provides information on the figure for waste in tonnes made by three companies named A,B and C from 2000 to 2015.
It is clear from the graph that company A and B produced less waste between 2000 and 2015, whereas the amount of waste produced by company C grew gradually throughout the years.
In the first year 2000, the quantity of waste that company A made began at precisely 12 tonnes, the highest level compared to company B and C, with the figure for waste being a bit lower than 9 tonnes and slightly over 3 tonnes respectively. This amount of company A declined gradually over 15 years, reaching about 11 tonnes in 2010 and slightly under 9 tonnes in the last year 2015. With the same downward trend, Company B’s amount of waste dove over 15 years and reached exactly 3 tonnes in 2015 apart from a brief rise of nearly 2 tonnes from 2000 to 2005.
In sharp contrast with the other two companies, the quantity of the produced waste from company C saw an upward trend throughout 15 years. There was a slow rise in this figure of 3 tonnes in 2005 and approximately 2 tonnes in 2010, until it reached a peak of 10 tonnes in 2015.
