How did they get 8.6? Is there a conversion that
(LBS/PERSON/DAY) MSW GENERATION PER CAP V - 18-09% -1E-05x + 0.0644x - 169.09% - 249650x -26-OBX- GE+10 N 0 1950 1960 1970 1980 1990 2000 2010 2020 2030 TIME (YEAR) GRAPH FOR: Time vs Solid waste generation per person per day Let us say if we dont act at any moment, the MSW per capita will increase. To prove this, we say the year x=2025 and see wether it will increase: Algebraic function y = 1E-09x6 - 1E-05x5 + 0.0644x4 - 169.09x3 + 249650x2 - 2E+08x + 6E+10 y = 1E-09(2025)6 - 1E-05(2025)5 + 0.0644(2025)4 - 169.09(2025)3 + 249650(2025)2 - 2E+08(2025) + 6E+10 y~8.6 lbs/person/day maximum This means that if we let the issue on waste disposable, what the functions is that at maximum the MSW generation per capita will double up to 8.6 lbs/per person/day in 2025 from 4.9 lbs/per person/day in 2018. *Note: There will be discrepancy in the y-value since their are round offs given by the excel in the numerical coefficients
