Renewable diesel and sustainable aviation fuel (SAF) producer Montana Renewables announced July 22 that it intends to build additional water-treatment capacity at its Great Falls, Montana, facility.
This project will allow Montana Renewables to manage agricultural wash water, a byproduct of its production process, without shipping water to third-party locations.
“As we continue to deliver significant economic and employment opportunities for the Great Falls region and for Montana agriculture, we also play a key role in ‘America First Agricultural and Energy Dominance,’” said Bruce Fleming, the CEO of Montana Renewables.
“The planned addition to existing onsite water treatment will deliver sustainable, science-based water solutions that comply with regulatory standards while keeping the natural resources and economics within Montana,” he added.
An ordinary part of Montana Renewables’ operation includes washing renewable feedstocks such as canola or corn oils before those materials are used to produce renewable fuels.
This approach is used by the food industry in preparing the same vegetable oils for the supermarket shelf.
The resulting nonhazardous wash water is safely disposed of at permitted out-of-state facilities.
This includes shipping of water by truck and rail.
“As we expand our production, onsite water treatment is a logical improvement that serves Montana Renewables and Montana,” Fleming said.
A loan from the U.S. DOE is enabling Montana Renewables to expand its domestic renewable fuel production and create jobs, under which DOE approval is required before construction can begin on the additional water-treatment capacity.
