Feasibility of Study for Co-Locating and Integrating Ethanol Production Plants from Corn Starch and Lignocellulosic Feedstocks

By Robert Wallace, Kelly Ibsen, Andrew McAloon and Winnie Yee

The maturing corn-to-ethanol industry has many similarities to the emerging lignocellulose-to-ethanol industry. It is certainly possible that some of the early practitioners of this new technology will be the current corn ethanol producers.

In order to begin to explore synergies between the two industries, a joint project between two agencies responsible for aiding these technologies in the Federal government was established. This joint project of the USDA-ARS and DOE with NREL looked at the two processes on a similar process design and engineering basis and explored ways to combine them.

The first report (Phase I) describes the comparison of the processes, each producing 25 million gallons per year of fuel ethanol.

This report (Phase II) investigates combining the two processes at different points to examine possible advantages to collocation
