The present Field Study Project is concerned with the feasibility study of a biodiesel production unit from “Palaiologos Biofuels SA”. At first, the study provides a detailed description of the product, its production and its beneficial properties. Then, it examines the Greek and European law framework, as well as the present situation of the market in Greece and in Europe. Next, the main sources of sales and revenues are “traced” and the initial investment cost is estimated. The investment-financing scheme is also presented in detail. The study concentrates on operational and financial aspects of the project and draws on quantitative analytical tools like scenario analysis, cost modelling and investment analysis to provide clues about the feasibility, profitability and risk of the project.
