Dutch airline to turn used cooking oil into aviation biofuel


Associated Press

AMSTERDAM — Dutch airline KLM plans to use recycled cooking oil as biofuel to power flights to and from France in a move aimed at cutting carbon emissions.

Starting in September, KLM will begin more than 200 flights between Paris and Amsterdam using biofuel made from used cooking oil, the company said Wednesday.

KLM managing director Camiel Eurlings said in a statement the airline does not have to make any changes to its aircraft engines to use the new biofuel. The biofuel flights are intended to help reduce KLM’s carbon emissions while having a “minimum negative impact on biodiversity and food supply.”

Air travel is responsible for about 3 percent of greenhouse gases, but their share of global emissions is rising rapidly.

The European Union told airlines earlier this year they would have to cut their carbon emissions by three percent on flights to the continent in 2012 to fall within new pollution limits.

The limit is designed to encourage airlines to reduce greenhouse gases that contribute to global warming by switching to cleaner fuels or economizing on fuel consumption with lighter aircraft or more efficient flight patterns.

Eurlings said he expects authorization to be granted soon for KLM’s flights using the new fuel.

An Air France-KLM Boeing 747 using a 50 percent biofuel mix in one engine successfully completed a demonstration flight in the Netherlands in November 2009.

Forty people flew on the 90-minute trip, including the Dutch economic affairs minister, and the airlines said it was the first flight using biofuel to carry passengers. The plane had a 50-50 mix of biofuel and regular jet fuel in one of its four engines.

Virgin, Air New Zealand, Air Japan and Continental Airlines have previously completed similar demonstration flights using biofuel mixes.

    The conclusion is that Mayor Parker is clueless about energy.

    You might be interested in this study of various biofuels and fossil fuels on a well to wheels basis


    See especially Figure 7

    Now, the Dutch have figured out the conclusion that natural gas is a friendly option and you can get autogas at most stations.

    From figure 7 corn ethanol and brazilian sugar cane oil is an enviromental disaster for the very reasons you mention.

    Other than manure power (and waste dump power) note that recycled veggie oil is a great fuel, very environmentally friendly, on a total use basis (your analysis is correct; I just skipped that part of the analysis but I am very aware of that).

    Anyway, the fact that time after time I set out the used veggie oil and the COH refuses to take it shows that Houston shows how clueless the current mayor and administration is about energy

    I am also a biofuel enthusiast (and I will mention once again that COH does NOT pick up my used veggie oil in the container with recycle).

    Anyway, LNG has less than a 10% overhead for the compression which comes nowhere near the 25% wasted energy of the GTL process.

    “However, some other distillates with lower energy contents than diesel often sell at a relative premium to it due to other advantageous properties or relative scarcity and it seems that the focus in the near term is to target production of those products…”

    It is a near term focus is as you point out…

    Americans wasting energy.

    Someday we will be sorry..

  3. Biofuel Enthusiast says:

    Moron, you’re missing a few key points. 1 btu nat gas is not equivalent to 1 btu of diesel in terms of being viable transportation fuel. You have to either compress or liquify natural gas to make the fuel dense enough to transport. That requires a lot of energy to do… Diesel is pretty much the most energy dense liquid fuel at atmospheric pressure on both a mass and volumetric basis. If your process allows you to pick pretty much any kind of distillate as its output, which Syntroleum’s technologies do, diesel is probably the most logical output from an overall energy efficiency perspective. However, some other distillates with lower energy contents than diesel often sell at a relative premium to it due to other advantageous properties or relative scarcity and it seems that the focus in the near term is to target production of those products…

    From the NIST chemistry webpage cetane has a heat of combustion of 10694.8 kJ/mol or 668 kJ/carbon, which is very slightly better than ethanol.

    Of course burning CH4 directly would produce 33% more energy but why would we Americans ever want to conserve energy.

  5. Syntroleum Rules! says:

    DF makes renewable diesel. There are some major differences including the way its made, having higher cetane and FAR superiour cold flow properties.

  6. Energy Moron says:



    Yah, the subsidy of a buck a gallon for producing it benefitted Europe as of 2008. I don’t know the market right now except that it tanked when the depression hit.

    Biodiesel is really, really, really good stuff (especially when made from waste), as is methane generated from bovine or chicken plants (as well as waste plants).

    What is really sad is that your suggestion to have to go to Craigslist to get rid the product (I just want to give it away!) is just so reflective as the total failure of Democrats and Republicans alike to grapple with our nations energy challenge.

    Going back to the GTL stuff. GTL was originally envisioned by BP as a way of marketing stranded gas on the Alaskan North Slope. I did link to info on the Qatar GTL plant. Guess what. There is no gas market in Qatar. The gas is stranded (LNG is another option).

    Here in the US, besides sending very clean burning biodiesel to Europe (with transporting back dirtier gasoline on the tankers), what are we doing with natural gas.

    Hello, 50% of the power generation in the US is from mercury polluting high GHG producing coal plants.

    And our nations “leaders” can’t figure out what to do with this natural gas Godsend that quite frankly saved our national energy rear end?

    The future belongs to China with our corrupt libertarian/liberal leaders.

    Is there any true conservative in the House?

  7. Syntroleum Rules! says:

    As of right now…Syntroleum IS making fuel from it’s plant in Louisiana at a high net energy gain. Syntroleum is not operating a plant and has a completely different process of GTL as Shell so that point is extremely invalid. It was a great attempt though…Thanks for trying!

  8. Joe Dokes says:

    . . . individuals in the ‘hood here are producing fuel for their trucks with used cooking oil . . . would think an ad on craigslist would produce an outlet for anyone wanting to dispose of such in an environmentally friendly way . . .

  9. Energy Moron says:

    “DF is producing fuels at a high net energy gain.”

    Let’s just do some chemistry here. You know science, that which Americans are becoming increasingly challenged in.

    CH4 (natural gas): 889 kJ/mol (or 889 kJ/carbon), 4 hydrogens to 1 carbon

    C2H5OH (ethanol): 1300 kJ/mol (of 650 kJ/carbon), 3 hydrogens to 1 carbon therefore worse for global warming.

    Link on GTL:


    GTL is an exothermic process. Meaning releases energy (which is consistent with turning the high energy content CH4 into lower energy content ethanol). The Qatar plant is from public domain sources loosing 3 GW of energy through heat (about 2 GW can be recycled), which means that 5% of Texas can be powered on the energy wasted in the GTL process from that plant

    “DF is producing fuels at a high net energy gain.”

    All you have shown is that captains of US industry no longer even know chemistry and are merely trying to convert a (hopefully temporary!) difference in energy cost between natural gas and oil into a profit…

    Yah, and you are even incorrect in your history. Both the apartheid regime in South Africa and Nazi Germany used Fischer-Trope processes to generate liquids from coal on a large scale, not natural gas.

  10. Syntroleum Rules! says:

    GTL is a proven process and actually supplied the Germans with fuel. DF is producing fuels at a high net energy gain. Don’t let first generation ethanol cloud your judgement over 2nd and 3rd generation high tech fuel. And the smelly stuff…I hear that around the refineries smells like chicken lol, but when they get done with it in fact looks like water and is odorless.

  11. Energy Moron says:


    Back during WW II (the greatest generation) America made a whole bunch of sacrifices.

    Now we are the wasteful generation. The amount of energy and stuff America wastes is appalling.

    The future belongs to China

  12. Sammie Jo says:

    I just want to know if the air will smell like french fries cooking? Will we all end up smelling like we work at the local cafe? Will we all suddenly start craving fried foods? Will the people against people wearing perfume, be as adamant against smelling like old grease?
    Enquiring minds want to know.

  13. Bill in Houston says:

    Gee, I can’t wait for the Obama Administration to mandate we save all our cooking oil, cut every inch of marbling from our meat, and strain our peanut butter (all at our own expense) just so these follies will have input product…

  14. Energy Moron says:

    Mayor Parker’s gang, rather than have a feel good party (see other article on FuelFix this morning), is hindering rather than helping alternative energy.

    I have been putting out back in the original bottle my used cooking oil along the curve for the recycle collection for quite some time now. The recycle folks will not take it unlike other oil.

    Rather than waste the BTUs in natural gas through a GTL process it would be better to conserve energy, use natural gas directly,


    Mayor Parker is NOT on the ball with respect to renewables.

  15. Syntroleum Rules! says:

    This fuel is being exported from Louisiana from Dynamic Fuels, a joint venture between Syntroleum and Tyson Foods. The plant is operating at 75 million gallons of fuel per year! They have plans for many more plants as well, and Syntroleum has plans with a natural gas producer to build a much larger scale Fischer Tropsch plant using their GTL patented technology.
