The Columbia plant is a 40MGY plant that began operations in 2007. It is a highly efficient batch fermentation process designed by Delta-T. Corn is received by unit train from the Midwest. Located on the Columbia River, most the ethanol is shipped by barge to markets in Portland, OR and some is trucked to nearby markets. The Columbia plant does not dry its feed products contributing to its low carbon ethanol score through reduced natural gas demand while producing high-value high protein feed products. The ethanol is sold to customers in Oregon and benefits from the Oregon Clean Fuel program which values the low carbon ethanol produced at the plant and the high-value feed products are sold to nearby dairies, feedlots, and poultry farms.
