JEFFERSON CITY, Missouri– Defining a new level of success, the word “biodiesel” appears in the 2006 update of the Merriam-Webster’s Collegiate Dictionary, Eleventh Edition . This marks the first time that it has appeared in the dictionary, and signifies that biodiesel is becoming a household word. What’s more, word has it that Merriam-Webster put biodiesel on the short list of examples of new words added to the dictionary. That means “biodiesel” joins the ranks of “ringtone,” “soul patch” and “supersize” in drumming up interest in modern lexicography. The new dictionary defines biodiesel as: “a fuel that is similar to diesel fuel and is derived from usually vegetable sources (as soybean oil).” “Appearing as a word in the dictionary gives biodiesel the credibility that it deserves,” said Joe Jobe, CEO of the National Biodiesel Board. “It shows we are making an impact on getting biodiesel into the mainstream, and that is very gratifying.” Biodiesel significantly cuts harmful environmental emissions, promotes greater energy independence and boosts our economy. It has become America’s fastest growing alternative fuel according to the Department of Energy. Production tripled in 2005, reaching 75 million gallons. The industry is on track to double production this year, to 150 million gallons. More information on biodiesel can be found at www.biodiesel.org. To see other new words, visit Merriam-Webster.
