WE'RE SAVED!
Article excerpt from Discover magazine, April 2006 issue.
$this->bbcode_second_pass_quote('', 'T')he smell is a melange of midsummer corpse with fried-liver overtones and a distinct fecal note. It comes from the worst stuff in the world - turkey slaughterhouse waste. Rotting heads, gnarled feet, slimy intestines, and lungs swollen with putid gases have been trucked here from a local Butterball packager and dumped into an 80-foot-long hopper with a sickening
glorp. In about 20 minutes, the awful mess disappears into the workings of the thermal conversion process plant in Carthage, Missouri.
Two hours later a much cleaner truck - an oil carrier - pulls up to the other end of the plant, and the driver attaches a hose to the truck's intake valve. One hundred fifty barrels of fuel oil, worth $12,600 wholesale, gush into the truck, headed for an oil company that will blend it with heavier fossil-fuel oils to upgrade the stock. Three tanker trucks arrive here on peak production days, loading up with 500 barrels of oil made from 270 tons of turkey guts and 20 tons of pig fat. Most of what cannot be converted into fuel oil becomes high-grade fertilizer; the rest is water clean enough to discharge into a municipal wastewater system.
For Brian Appel - and, maybe, for an energy-hungry world - it's a dream come true, better than turning straw into gold. The thermal conversion process can take material more plentiful and troublesome than straw - slaughterhouse waste, municipal sewage, old tires, mixed plastics, virtually all the wretched detritus of modern life - and make it something the world needs much more than gold: high-quality oil.
Appel, chairman and CEO of Changing World Technologies, has prodded, pushed, and sometimes bulldozed his way toward this goal for nearly a decade, and his joy almost palpable. "This is a real plant," he says, grinning broadly. He nods at the $42 million mass of tanks, pipes, pumps, grinders, boilers, and catwalks inside a corrugated steel building. The plant is perched 100 yards from ConAgra Foods' Butterball plant, where 35,000 turkeys are butchered daily, surrendering their viscera to Appel's operation. The pig fat comes from four other midwestern ConAgra slaughterhouses. "To anybody who thinks this can't work on an industrial scale, I say, 'Come here and look.' This is the first commercial biorefinery in the world that can make oil from a variety of waste streams."
Still, Appel looks wearier than he did when
Discover broke the news about his company's technology (see "Anything Into Oil," May 2003). Back then, when the process was still experimental, Appel predicted that the Carthage plant would crank out oil for about $15 a barrel and rack up profits from day one. But the plant was delayed by construction problems, and federal subsidies were postponed. After it started up, a foul odor angered town residents, leading to a temporary shutdown in December 2005. Production costs turned out to be $80 per barrel, meaning that for most of the plant's working life Appel has lost about $40 per barrel. As recently as last April, he feared that the whole operation might implode. "There have definitely been growing pains," he says. "We have made mistakes. We were too aggressive in our earlier projections."
But now, after more than $100 million in private funding and $17 million in government grants, several hurdles have tumbled. The Carthage plant has been optimized and is expected to turn a small profit. A tax credit has leveled the playing field with other renewable fuels like biodiesel and ethanol. Appel is confident that new ozone scrubbers and other equipment will abate the odors. State officials are warily optimistic. "We are not hoping to shut them down [permanently] and take away jobs," says Connie Patterson, spokesperson for the Missouri Department of Natural Resources. "We have given them a window of opportunity to solve the problem."
Anybody else read this in its entirety? Last I heard, that plant down in Carthage was still shut down...
