BLACKSBURG, Va., Aug. 20 (UPI) -- U.S. scientists are developing portable pyrolysis units that can convert poultry litter into bio-oil in a system that addresses biosecurity issues.
Virginia Tech Associate Professor Foster Agblevor, who is leading the research, said the technology can convert poultry litter into three value-added byproducts -- pyrodiesel, producer gas, and fertilizer.
The pyrolysis unit heats the litter until it vaporizes, the scientists said. The vapor is then condensed to produce the bio-oil and a slow-release fertilizer is recovered from the reactor. The gas can then be used to operate the pyrolysis unit, thereby making it a self-sufficient system.
More than 5.6 million tons of poultry litter are produced each year in the United States.
“The self-contained transportable pyrolsis unit will allow poultry producers to process the litter on site rather than having to haul the litter to a separate location,” Agblevor said. “In addition, the thermochemical process destroys the microorganisms reducing the likelihood of the transmission of disease to other locations.”
The research that included Sedat Beis, Seung-Soo-Kim and graduate students Ryan Tarrant and Ofei Mante was presented Monday in Boston during the 234th national meeting of the American Chemical Society.

There is no madness here that I see.
With the CAFO regulations now from the EPA, large livestock/poultry/farrow-to-finish and other operations are going to be looking for industrial ways to handle their manure (ie, “litter”). There is no madness here: The stuff has to be dealt with in some manner.

Litter can’t be out in the open for more than 72hrs after clean out of a poultry house or you can be fined,,unless it’s under a barn..you can easily spread 50 ton on 40 acre (2 houses),people with 4 to 6 houses on 40 acre start running into problems with getting rid of it,,if there is a way to use the stuff (even just in farming equip)cheap would be a good thing..
Does goose poop work as well? I know of a lot of lakes and ponds covered with this stuff.
But the real question is, can a heat exchanger be added to it so it can be used to heat the house? Kinda like the woodburner in my Dad’s yard.
Seems to me that a chicken crap burning stove would be downright popular in some areas.
Per the article, the process fuels itself as long as you keep providing the chicken poop.
Let me know when you invent one,,I’ll pass the word around,,could also use a hot water heater model,,
Only works in powerstrokes no doubt !........:o)
Here’s the problem with just spreading it (or any other manure from a declared CAFO):
The EPA demands that you have a PNP (Permitted Nutrition Plan) wherein you have to evaluation the ability of the soil/crop where you’re going to spread the stuff to use the NPK in the manure. Your disposal plan is only approved up to the point where your crop consumes all the nutrients. Then you have to find more cropland on which to apply it.
If someone is spreading it on homeowner’s yards/lawns where people just want to grow grass or pasture, that’s great, but it will take only a couple of high-precip events with runoff for the EPA to crack down on this too.
With the hassle of CAFO regulations, I expect to see lots of digesters and bio-fuel processing of manures going forward — simply because they will involve less paperwork and more profit than putting the manure back into the soil, which would be the simplest thing to do.
Never underestimate the power of bureaucrats and greenies to make what used to be as simple as you describe become much, much more complicated.
Can anyone explain to me the Leftist Eco-Nuts utter fascination with fecal matter in any way, shape or form? LOL!
I need my chicken manure. (That’s the correct term.) It composts for two years, then turns my clay garden soil into Black Gold, Baby! :)
I’m certainly not going to run my truck on it when it can go to better use on the garden producing food for my family.
To paraphrase:
Reporter: Mrs Truman, can you get the President to stop saying “poultry litter?”
First Lady: Honey, it took me thirty years to get him to say “poultry litter.”
It’s called “more poultry litter.”
:)
I was mocking the the anti-ethonal folks, you know, the ones who say ‘do you know how much energy corn to ethonal uses?’!
I also recommend rabbit manure.
Oh, sorry. My bad — been baling hay for the last three days and I’m cranky.
Mock away. ;-)
Reminds me of the movie Slapstick of another kind. Pat Morita played an Ambasador who’s minaturized nation was ran on chicken manure.
