The provided graph illustrates the waste production levels of three companies (A, B, and C) over a 15-year period from 2000 to 2015.
Overall, noticeable fluctuations in waste production were observed among the three companies throughout the 15-year period. While Company A and Company B experienced reductions in waste generation, Company C showed a significant increase in the amount of waste produced. The unit of measurement is in tonnes.
In 2000, Company A was the leading waste producer, generating 12 tonnes, while Company B and Company C produced approximately 9 and 6 tonnes respectively. By 2005, there was a slight increase in waste generation for Company B and C, whereas Company A decreased its waste output by around 1 tonne. From 2005 to 2015, Company A reduced its waste production by about 3 tonnes, Company B managed to decrease waste generation by approximately 7 tonnes, and Company C notably increased its waste production by 4 tonnes over the same period. By 2015, Company C’s waste production had risen to 10 tonnes, surpassing both Company A and Company B, whose waste production levels had decreased to 8 and 3 tonnes respectively.
For Company A, waste production started at 3 tonnes in 2000, peaked at 12 tonnes in 2005, decreased to 9 tonnes in 2010, and further reduced to 6 tonnes by 2015. In the case of Company B, waste production began at 9 tonnes in 2000, fluctuated but returned to 9 tonnes by 2010, and then dropped to 3 tonnes by 2015. Company C’s waste production remained steady at 6 tonnes in 2000 and 2005, increased to 9 tonnes by 2010, and remained stable at 9 tonnes in 2015.
