Imperium Renewables, the parent company of Seattle Biodiesel, is slated to announce later today that it's inking an agreement with the Port of Grays Harbor to build a 100 million-gallon-a-year biodiesel refinery on port property in the Aberdeen area.
According to a company spokesman, the plant would be one of the largest in the country. (By comparison, Seattle Biodiesel's existing refinery makes about 5 million gallons a year.)
According to Sen. Maria Cantwell, the $40 million plant would employ about 50 workers.
The move comes at a time when biodiesel -- derived from vegetable oil -- is in some places cheaper than conventional diesel.
