AgroWaste to Oil a Growing Market

EvilTwinSkippy writes "Last May Slashdot covered the story of Changing World Tech's opening of a plant that converts agricultural waste to oil. Fortune magazine has picked up the story, and followed up on their success. Apparently the turkey guts are not as profitable to recycle as hoped, the company paying $30-$40/ton for animal offal. They are producing diesel fuel at $80/barrel (compared to $50/barrel for petroleum derived diesel). However, the plant has been successful enough to spawn ventures in Europe and the U.S. A pilot plant in Philadelphia has successfully used the process to safely break down and extract oil from sewage, medical waste, electronics, even leftovers from petroleum refining. The solids are metal, pure carbon, and fertilizer. And aside from gas and oil, the only other thing the system produces otherwise is sterile water."

    Given that there is legitimate concern that we will soon reach -- and maybe already have -- peak oil production, the $80/bbl price may be competitive before too long.

    The real problem is that there just aren't enough turkey guts in the world to replace crude oil, and the grain that the turkeys are fed is produced by an agricultural industry that is totally dependent on petroleum-derived fertilizers and pesticides.

    No, I wrote a report on this company last year for a college assignment. This process consumes less energy than it produces, but not enough to be economical yet. Really the only benifit from it now is disposal of organic waste as the oil produced isnt cost effective for the market yet.

    Wouldn't it be truly ironic if the medical waste was liposuction fat (think Fight Club)? Then, the clinical obesity afflicting one in three Americans would itself be powering the automobiles that are, in part, responsible for the obesity.

    Oil prices are rising. A 50% rise is sufficient to make this profitable, and in the mean time, it's a good way to get rid of hard-to-handle wastes like worn-out tires and used motor oil.

    Really stupid. If politicians weren't in the pocket of industry, this would be outlawed. Make that OUTLAWED! Then, maybe the slaughterhouses would be _paying_ to have the offal disposed of - and not by dumping it anywhere they own a piece of land, either.

    Yes, and no.

    No process can be 100% (or more) efficient -- the CWT process is about 80%-85% efficient. That means that the remaining energy is turned to waste, so it obviously produces less energy at the end than when it started.

    However, when looking at usable energy, the system is highly efficient. Most of the energy in the CWT comes from the energy stored in the "feedstock" (turkey guts, etc.). This is energy that would normally be slowly released as waste energy as the feedstocks decomposed. instead, this process turns that energy into useful products, primarily diesel fuel. Removing the energy from the feedstock, the process produces about 4-5 times more usable energy than it uses.

    Yes, but so does every other process in the known universe(*). The point is that they are taking "waste" and getting use out of it. This wouldn't be a net energy "source" like drilled oil, but it would be an energy currency like hydrogen. The advantage here is that, since it is hydrocarbons they are producing, you can use it in manufacturing of plastics, etc.; hydrogen's not a useful construction resource (until metallic hydrogen becomes practical, that is).

    With the volatility of crude oil the way it is (heck, it's gone up over 5% today!) for no logical reason (they cite "unseasonably cold weather in the northeast US and Britain" - winter is always cold, and our reserves are higher than they were last year - go figure), any other alternatives that don't require a huge infrastructure change are welcome. Producing "petroleum" from waste is potentially a great way to reduce the volatility of crude oil.

    It does nothing, though, to address the issues of using a carbon-based energy currency and the CO2 byproducts from that. It's definitely a novel idea, and the sooner we develop alternatives the better (it's a whole lot more difficult to develop alternatives when your reserves are depleted due to increased periodic costs - i.e., higher cost for crude oil).

  11. Supply, Demand, Refinement, Scale by visionsofmcskill · · Score: 5, Interesting

    80$ a barrell vs 50$ a barell may SEEM to be a failure, but it is actualy an incredible accomplishment that will become increasingly viable in short order.

    I've done some research on this topic and found out that californias agricultural waste which is mostly funneled down into a southern californian dessert lake area could supply enough fuel to satiate the US oil supply.

    There is enough un-inhabitable land area in southern california to process all of this waste and thus fully liberate the US from foriegn oil, not to mention create a replenshible power supply compatible with our current prevelant technology (gas based power).

    The greatest contorl over per barell pricing is from the supply made available from oil producing states greatly controlled by OPEC. As world consumption increases and known stock piles decrease and cease over the next 30 to 50 years the price per barrell will continualy rise. And will certainly exceed 80$ a barell probably within the next five to ten years.

    The only reason oil is at 50$ per barell is due to it's massive scale, if waste based oils had even a hundreth of the scale that our current oil industry uses, or even a thousandth of the money, industry and investment it does, we would probably see prices drop well below the 50$ mark.

    And this is speaking of the technology in it's current form. Though it may have some initial ineffeciences which have made the cost 80$ a barrell, cost saving measures through natural refinment of the processing of waste will undoubtably greatly improve the procedure within the next few years and continue.

    I would say that 80$ a barrell is an astounding accomplishment which given the finite and defintie bounds of drill based oil will rapdily become an extremly attractive alternative fuel source.

    Im surprised at the pesimisitc tone from slashdot. I also speculate that in the next ten years or so we shall see the major players seek control over this new market to sell oil to the world market as their drill based supply dwindles.

    Actually, it does address the fact that there's CO2 byproducts: It's recycled carbon. The problem with using petroleum pumped up from the depths was that this was carbon that was locked up. If we grow plants, turn them into oil, and then burn them, the net change in CO2 is zero.

    They claim that the methane produced from their process produces all the energy to drive their distillation process, and I think that's perpetual motion machine junk science.

    Perpetual Motion? I don't think you know what that means. They are adding TONS of turkey offal. That is where the energy is coming from. It isn't perpetual motion if you are constantly adding things (like, um, turkey offal).
