By varying the value of
one variable while keeping the others unchanged, its
effect on the break-even price of biodiesel was studied.
Noordam and Withers (1996) reported that, on average,
a $0.01/kg increase in the canola seed cost would increase
biodiesel price by $0.03/kg. A $0.11/kg increase in
glycerine price would reduce the biodiesel price by $0.01/
kg. Because other factors, such as the ones related to
process operation, were not considered, the results from
such an analysis cannot be generally applied to other
biodiesel plants
