The graph below shows the amount of waste produced by three companies over a period of 15 years

The line graph illustrates how many

tonnes

of

waste

is generated by the company A,B and C from 2000 to 2015

Overall

, the

waste

produced by all three companies shows variation over the given time frame. In the year 2000, company A had the highest

waste

production of all years,

while

, it declined gradually over the years, generating about 9

tonnes

in 2015, which is quite lower than what it discharged in earlier times.

Similarly

, sector B produced the

of 8

tonnes

in 2000,

conversely

this

generation of

waste

increased to approximately 10 units in 2005, after which it showed a dramatic dip to 3

tonnes

in 2015, showing the lowest reading,

until 2010, from 2010 onwards there was a sharp rise to almost 11
