However, pollution from traditional fuel ethanol production seriously affects the survival and development of the fuel ethanolndustry. The establishment of an industrial ecosystem which is based on fuel ethanol-producing enterprises, including growers, ethanolroducers, decomposers, collectors of renewable resources, etc, has become an effective way to sustainably develop fuel ethanolAccording to the waste treatment and resource utilization, fuel ethanol production models may be divided into three cases: traditionalproduction (case I), waste treatment case I) and industrial ecosystem( case I). In this paper, these three cases were studiedcomparatively by the improved emergy analysis method and index system. The results showed that compared with case I, the emergyyield ratio of case I was increased by 59. 37%, and the environmental load ratio was decreased by 75. 39%, through waste treatment andintermediate water utilization. With an extended industrial chain and increased recycling, the emergy yield ratio of case Il was increasedby 86. 19%, and the environmental load ratio was reduced by 82.98%, when compared with those of case I. For these three prcases, the sustainable development capacity was ranked in the order of case I
