One of the most important environmental fuels is bio-ethanol. Ethanolproduction will reduce the consumption of crude oil and reduce environmental pollution. Generally,bio-ethanol can be produced from various types of raw materials. By considering Iran's potential forproper raw materials, bio-ethanol is one of the best fuels that can be replaced by gasoline. The purposeof this article is to address the issue of location optimization of bio-ethanol production centers in Iran.In this article, the provinces of Iran for constructing bio-ethanol production centers are ranked using thedata envelopment analysis method.
