Parameters	With minimum Cost
Parameters	Landfill	Agr-field
Fraction of FGDG	2.44E-03	0.99
Total direct environmental release (g)	7.60 E-04	5.24
Cost	0.20	36.21

G(1) = 2.44 E-03 mass balance constraint

G(2) = 0.29 Substitution ratio constraint for agricultural field

G(3) = 3.64 E-03 Substitution ratio constraint for landfill

G(4) = 2.70 E-03 Agricultural field leachate concentration constraint for chemical 1

G(5) = 2.30 E-05 Landfill leachate concentration constraint for chemical 1
