摘要

The objective of this study is to obtain a realistic evaluation of the potential role of microalgae as a biodiesel feedstock in a tropical setting. First, microalgae economics are estimated, including the detailed design of a 400 ha microalgae open pond production farm together with the microalgae biomass and crude oil production costs calculations. Sensitivity analysis and a stochastic evaluation of the microalgae venture chances for profit are also included. Next, microalgae potential for biodiesel production is compared to traditional oil crops such as soybeans and African palm. This comparison is performed using the Northeast Region (NER) of Brazil as background. Six potential biodiesel feedstock sources produced in the NER and microalgae are compared considering selected environmental, economic and social sustainability indicators. Finally, in the third chapter, the study proposes a cropland allocation model for the NER. The model aims to offer insights to the decision maker concerning biofuel development strategies and their impact on regional agricultural feedstock production. In the model, cropland allocation among three agriculture feedstock sectors, namely staple food, commodity export and biofuel is optimized through the use of the multiple objective technique referred to as compromise programming (CP). Our results indicate a projected microalgae total production cost of R
