Editor’s Note: This is Part One in a series of articles by John Rarrick examining how small businesses are turning to Waste Vegetable Oil (WVO) to tighten their belts while simultaneously reducing their carbon footprints.

Like many small business owners, Jose Duarte, Chef/Owner of Taranta, in Boston, MA, is constantly looking for ways to control costs in an economic climate that has no sympathy for the little guy. Fortunately for Duarte, discovering ways to trim his operating overhead also led to a “greening of Taranta.”
“I was looking for ways to cut our costs and I stumbled upon an article about these people running their diesel cars and trucks on fryer oil. I figured that was a good place to start,” said Duarte.
Calculating that he could save a few thousand dollars a year on the fuel costs he incurred from daily runs to his seafood vendors, Duarte turned to Boston-based Green Grease Monkey for advice on converting the restaurant’s Chevy Silverado to run on WVO.
Now he recycles not only his own grease, but that of the restaurants owned by several of his friends.
What was admittedly at first an experiment, turned into an obsession, with Duarte becoming increasingly more involved in the environmental impact of his business. After implementing a series of changes and upgrades to the restaurant, including an in-house carbonating system that enables them to make their own sparkling water supply, a recycling/composting program, and a move to utilizing more organic ingredients, Taranta received the City of Boston’s Green Business Award for 2008.

Drivers of WVO-powered cars will either love or hate the work of Boylston, Massachusetts-based Owl Power Company. Owl Power’s founder and CEO, James Peret, has developed and launched a product they call the Vegawatt, a fully automated cogeneration system for restaurants, designed to run on waste vegetable oil.
Peret’s team says the Vegawatt system is more than just a basic generator. The device, which is about the size of consumer-size refrigerator, includes a turn-key waste vegetable oil (WVO) refinery that automatically transforms even the most disgusting used cooking oil into fuel appropriate to supply up to 25% of the electrical power a restaurant requires for lights and hot water.
I had a chance to speak with Ben Prentice, VP of Sales at Owl, who gave me the low-down on the Vegawatt.

Last week, The San Francisco Chronicle reported on the success of a city-wide holiday recycling drive, which looked to top the more than two tons of used cooking oil San Fransicoans unloaded over Thanksgiving weekend. The grease will go to power the city’s fleet of fire trucks, ambulances, Muni buses and other vehicles.
According to Tyrone Jue, spokesman for the San Francisco Public Utilities Commission, programs like this can also put a huge dent in the city’s sewer repair budget, as kitchen grease is one of the major causes of municipal water pipe damage, responsible for over 50% of sewer emergencies each year.

As winter dumps her usual dose of cruelty here in New York’s Hudson Valley, like many drivers of veggie oil-powered cars, I have begun reading up on how to best prepare mine for the cold season.
There is a LOT out there on the web regarding the proper blending of WVO, diesel, kerosene, etc. After several weeks of reading several hundred blogs and forum posts, here is what I’ve deduced: Nobody really knows.
And here’s what else I’ve deduced…it really doesn’t matter. I’ve put every conceivable combination into my single-tank 240D. With the exception of a slight increase in power when using a higher ratio of dyno-diesel, there is no significant difference in performance or MPG.

Powered by used vegetable oil from Colorado restaurants, a new ski shuttle service is now offering “carbon-neutral” luxury shuttle service from Denver International Airport to Colorado ski resorts like Vail, Aspen, and Breckenridge.
Last month, Denver waiter-turned-entrepreneur Kristopher Klain started offering a more eco-friendly airport shuttle alternative in Colorado Green Shuttle’s flagship seven-passenger retro-fitted Ford Excursion, fueled by 100% straight vegetable oil.

Last week, 46,000 revelers finally broke camp and split the scene of this year’s Burning Man festival, The Green Man. You could call it the "biggest party in the world," though it defies categorization and convention: part art, music, rave, pyrotechnics show, and costume orgy, it’s probably the only place in America you’d see a 1,000-foot-tall mushroom cloud intended for politically-minded artistic expression.
Yep, that’s right - a 1,000 ft. mushroom cloud, and no,

It's all fun and games until the IRS knocks on your door. At least that's what Bob Teixeira must be thinking after his home state of North Carolina fined him $1,000 for converting his 1981 diesel Mercedes to run on straight-vegetable-oil (SVO). Bob was minding his own business when fuel inspectors, out to nab weekend-RVers using illegal fuel, noticed his "Powered By 100% Vegetable Oil" bumper sticker. After being fined
