It provides for those considering small-scale ethanol production: 1) a starting point to incorporate ethanol production into farming operations, 2) information that investors and financiers can use to evaluate prospects for particular ethanol production ventures, and 3) some yardsticks to assess the profitability of incorporating ethanol production into operations. Fundamental principles are the main emphasis. Although underlying theory is presented, the information is carefully selected for its direct practical value.
