In previous economic studies of biodiesel production,
the main economic criteria were capital cost, manufacturing
cost and biodiesel break-even price. Results of
three recent studies are given in Table 1. Nelson et al.
(1994) evaluated the economic feasibility of a plant
producing approximately 100,000 tonne/year of biodiesel.
Beef tallow was transesterified with methanol in
the presence of an alkali catalyst.
