Imperium Renewables recently celebrated the official opening of its Imperium Grays Harbor biodiesel facility in Washington state. With an annual capacity of 100 million gallons per year, it is the largest biodiesel production facility in the U.S.

"The launch of Grays Harbor represents a coming of age for the biodiesel industry. This facility has the scale and the systems to produce fuel comparable to petroleum diesel that meets or exceeds ASTM standards." -- John Plaza, President, Imperium Renewables
