Fish Oil and Biodiesel

Biodiesel is an engine fuel manufactured from renewable sources, such as vegetable oils, recycled cooking greases or oils, or animal fats. Biodiesel is a U.S. EPA-approved substitute manufactured to established industry standards. Shore-based and floating groundfish processors produce approximately eight million gallons per year of fish oil as a byproduct of fishmeal production. Much of the oil is used in the process as boiler fuel for drying the fishmeal or exported to Pacific Rim markets for livestock and aquaculture feed supplements and other uses. In 2001, with the assistance of AEA and the Alaska Science and Technology Foundation, processor UniSea Inc. conducted successful tests of raw fish oil/diesel blends in a 2.2 MW 2-cycle Fairbanks Morse engine generator. Since then, the company has expanded the operation and used over two million gallons of 50-50 raw fish oil-diesel blend for power production between July 2002 and June 2004. In 2010, Alaska Waste opened Alaska's first large-scale biodiesel plant. The plant produces 250,000 gallons of biodiesel annually with the waste vegetable oil that is gathered from local restaurants. Alaska Waste plans to fuel up to 20 percent their vehicles with the biodiesel.
