Overview: In the United States, corn has traditionally been the feedstock of choice. In fact, through 2006, 93% of the ethanol produced in the U.S. was produced exclusively from corn. The remaining feedstock came from other starch-based sources like sorghum (milo), wheat, barley, beverage waste and cheese whey.

Realizing the future potential of all types of ethanol and its wide array of uses, Midland has made a concerted effort to create products that are compatible with the processing, loading, transporting, unloading and storage of the chemical, no matter its feedstock.

Midland Experience

In addition to its industry-leading valves, Midland also offers rupture disc devices, actuator systems, level measurement gages and other railcar equipment that can be utilized in the transportation of ethanol products, all while guaranteeing that its products meet or exceed Association of American Railroads regulations.
