      This is a kind-of 'old tech' come back in a new form. Animal fat used to be used to produce candles and lantern oil; so the idea of using it for power isn't a new one.

    • Fried chicken is typically boiled in oil, typically canola or some other vegetable oil, and then salted and spiced. This is so you don't smell or taste the actual carcass.

      One also wonders why they switched from the previous use... Where the expected higher oil prices and/or some sort of biofuel subsidy good enough to make it cost effective, or did feeding animals their own ground up con-specifics break some new health and sanitary regulation?

      I suppose they could also have just taken advantage of some improvement in refining technology to change the point of combustion. I'd suspect that a coal-fired plant wouldn't even notice some chicken fat mixed in with the coal; but that the price per ton paid for the fat would be unexciting; while, with the right refining technology, you could turn those same lipids into a vehicle fuel, which is rather more valuable per ton....

      Unlike cattle, chickens are not "fattened up". Marbling is not a desirable feature in chicken meat. They get plenty of residual fats from the soybean meal that constitutes nearly half of typical feed. The chicken fat was probably used in pet food or cattle feed previously.

    There was a plant owned by Renewable Environmental Solutions near Carthage, MO that would take leftovers from Tyson's chicken plants and turn it into various oils, including fuel. Problem was that the plant *stank* and the wind sometimes blew the odor into town, leading to many complaints and attempts to fix it.

    Eventually the state shut 'em down because they were unable to control the smell. Maybe this place in Louisiana is way out in the middle of nowhere, so they won't have to worry so much about the neighbors complaining.

      Supposedly they were unable to conclusively link the odor to the plant - people complained about the smell even when the plant wasn't operating. The state suspension was only temporary and the plant operated afterward in face of more complaints. But despite having proven that the odors were not coming from their plant and spending millions on upgrading tech to deal with the potential odors the whole thing kinda went belly-up when the parent company declared bankruptcy.

      The mysterious death of the chicken-fat car
      By: Timothy P. Carney
      Senior Examiner Columnist
      May 20, 2009

      As President Barack Obama unfurls his fuel-economy standards and Congress takes up global warming regulations, it’s useful to remember that what emerges from environmental policymaking is not necessarily what’s best for the planet, but instead what’s best for special interests.

      Consider the epic and somewhat bizarre struggle over clean fuels that ended last week. As usual, special interests were central to the drama. But the antagonists seemed right out of a Monty Python sendup of Washington politics: An oil company, hoping to profit from making trucks run on chicken fat, was thwarted by the soap industry’s lobby.

      The chicken-fat story is a cautionary tale about how environmental policy actually gets made.

      It began in 2005, when President George W. Bush signed an energy bill including a $1-per-gallon tax credit for “renewable diesel” fuel created through “thermal depolymerization.” Writer Rina Palta reported in the liberal American Prospect that Rep. Roy Blunt, R-Mo., wrote the measure “to benefit a floundering company in his home district that produces boiler fuel from turkey offal, which did not qualify chemically as ‘biodiesel.’ ”

      At the time, Congress was eagerly providing subsidies to turn plants and animals into fuel, so it didn’t seem farfetched to boost the cause of fowl entrails. But unintended consequences soon arrived, proving once again that the biggest companies usually find a way to profit from government intervention.

      In April 2007, the Internal Revenue Service ruled that Blunt’s tax credit had broader applications. Within two weeks, ConocoPhillips and Tyson Foods saw that the IRS had opened the door for a joint venture to melt chicken, cow, and pig fat into diesel fuel. Conoco Chief Executive Officer James Mulva was honest about his unusual undertaking: “It’s not profitable without the $1 per gallon tax credit,” he said at a news conference.

      But this renewable fuel had enemies. First, Democrats didn’t like any subsidy that helped an oil company like Conoco. (Blunt, for his part, said he never wanted to help oil companies, and that the law should be changed.)

      Second, business lobbyists were also working to kill the subsidy for chicken fat. The obvious opponents were chicken fat’s competitors — the companies that turn vegetables into diesel fuel. The National Biodiesel Board, which spends nearly $1 million a year on lobbying, pushed hard to ensure the $1-per-gallon subsidy for clean diesel didn’t also apply to the Conoco-Tyson operation.

      But the issue of “renewable biodiesel” also turned up on the lobbying filings of the Dial Corporation and the Soap and Detergent Association. Just as ethanol subsidies have driven up the price of food, it turned out that fat-to-fuel subsidies boosted the cost of manufacturing soap, which is also made of animal fat. So Dial and the Soap and Detergent Association, displeased that Tyson now had somewhere else to peddle its fat, also lobbied to kill the chicken-fat diesel subsidy.

      While their own interests were obvious, the soap and biodiesel lobbies argued that chicken-fat diesel was not good for the environment. But the Environmental Protection Agency ruled this month that “biodiesel or renewable diesel made from animal fat or used cooking oil results in an 80 percent reduction from carbon emissions versus petroleum diesel,” according to Darling International, a company that deals in animal-fat diesel. Darling added in its first-quarter 2009 report, “That is the highest level of carbon reduction available

      The problem wasn't the stink. It was the economics. From the get go, they were relying on subsidies [ncpa.org] to make the process pay. These kind of businesses sprout up whenever there are government subsidies to be had or fuel prices spike. Their prospectuses will have a phrase that states that the company isn't profitable if you take away the subsidies or it will be profitable if the price of fuel rises faster than the rate of inflation.

      The findings are new, but disturbing for the future of biofuel.

      To put this in perspective, the newspaper article you link to describes some scientists who've done a computer simulation of burning mixtures including biodiesel (a particular type of biofuel), and predict that it will produce a greater amount of PAHs, which are known to cause cancer, than simulated pure fossil fuels. As far as I can see, they've not even burnt anything.

      Assuming real experiments match their simulation, the mixture will most likely be tweaked a bit--some chemical change, some additive, or something--to bring down the resulting amount of PAHs. We already drive around with catalytic converters bolted to our cars to clean up various pollutants. What you've described is a minor pothole in biofuel development, not the roadblock you seem to be implying. By far the greater challenge is how to devote the necessary land to grow biofuels while we simultaneously increase food production to feed a growing world population, and try to conserve land for nature.

  • I read in a few places that I can't remember right now that it takes feeding an animal 26 calories to get 1 calorie of food out, by eating their meat. In other words you have to put more energy in than you get out. This is good for Tyson's if this is about waste they could not do anything else with. It isn't an alternative energy solution though. It isn't even an efficient way to get food.

I don't think anyone is selling this as "the solution to oil dependence" or anything, but it *is* a way to recycle waste from a food production process that will occur anyways.

      Well, the 26 calories is probably as much of a guess as the other figures I've heard reported, anything from 2 to 100.

      The thing is, those calories, 26 if you like, can come from stuff that humans can't eat, like grass. Animals can (and do) graze on farmland that isn't really terribly suitable for growing crops. Without raising animals for meat, most of the people in the world would starve.

      • Factory farms feed cows other things than grass because it is more efficient ( cheaper and more profitable). Grass fed beef would be expensive beef beyond what many Americans can afford, let alone other people in the world.

    I have a friend who produces biodiesel semi-professionally (sells to local farmers to run their tractors and other farm equipment, the rest is unofficially sold to friends) and for a while he was using rendered chicken fat. The raw material stinks like hell, but the resulting biodiesel doesn't really smell like much of anything. Remember that the manufacture of biodiesel is a chemical process that changes the oil into something else. The chicken fat no longer exists at the end of the process. Any odor is due to particulate or a fraction of oil that wasn't completely converted.

    Generally all biodiesel smells the same unless it's been manufactured improperly. I've managed to get some in my mouth before (a siphoning error). It doesn't have much of a taste but it coats your mouth with a terrible film that is very hard to get rid of.

    One time I was over at the plant with my dog. She managed to find an open container of chicken fat and stuck her head in there. I don't know how much of it she ate (drank? gulped?) but you can imagine, if you dare to, what sort of things were coming out of the other end of the dog for several days afterward. Oh god...
