Ethanol From Waste Straw 449

phcrack writes "The CBC is reporting that 'Iogen Corporation of Ottawa has developed enzymes to break down waste straw and wood chips into ethanol on a commercial scale.' Apparently traditional ethanol from food crops like corn used at least as much energy to create as they released when burned. It's nice to see that big oil companies are helping fund a project like this too. It's very rare today to hear of a major company throwing money at a research project since the '80s."

    Around here "gasohol" is a 10% ethanol, 90% gasoline mixture. Any company can find a way to make that 10% ingredient cheaper than their competitors will find themselves in a very enviable position. It's smart business.

      It's smart business.

      Ethanol is only a smart business because it is subsidized (like oil, but that is another story). The only smart energy business is that in which net positive energy can be attained. That is, the product will produce more energy than it takes to manufacture it. Out of all forms of synthetic energy, wind, hydroelectric and some solar types will produce net positive energy.

      We need to use what is left of our non-renewable fossil fuel supplies to build these replacement supplies. Unfortunately, these all generate electricity and there is no current method of storing electricity with the density of current oil-based products. We'll need some of that energy to develop hydrogen and electrical storage.

      Water is a remarkable battery if we could manufacture a fuel cell affordably (i.e. - out of non-noble metals like platinum). Just add electricity and you've got H2 and O. Lovely.
      • I bet you've never tried to do electrolysis of water. It takes a fair amount of electricity, but only tiny bubbles of hydrogen and oxygen. And it'll take a lot of trouble to store and transport these gases. So don't hold your breath for a practical fuel cell any day now.

        When will people quit repeating this falsehood? It's been disproven over and over. You can trace most of these claims back to some named David Pimental, along with the number "70% more". The most recent study that disproved it that I am aware of (in a long chain of them) was by the USDA in 2002. Not only is there a 34% net energy gain (and there is tons of room for technological improvement), but of the energy used to produce the ethanol, only 17% came from liquid fuels such as gasoline.

    • Of course it is. And many versions of "reformulated" gasoline are simple mods on gasahol. However, there's also E85, which is 85% ethanol and 15% gasoline -- note they're still using gasoline as a component. E85 has been found to be more or less readily compatible with current technology and many cars/trucks currently produced will run off of E85 with no modifications required. Just fill up.

      Cellulose ethanol is a terrific idea, and saves food crops for food purposes...

      Actually, it's a myth that the ethanol process uses corn that goes for food. Most corn doesn't get processed into food [usda.gov]. It is used as animal feed and the by-product of corn ethanol production is a distiller's mash that is actually better for animal feed since it is high in protein and rich in water-soluble vitamins and minerals. Because the fermentation process removes only starch, all the remaining digestible nutrients are left in the distiller's grain.

      Additionally, the net energy output of corn ethanol is 34% (PDF) [usda.gov]. It does not take as much or more energy to produce a gallon of ethanol. Plus, this is using traditional distillation methods. If we really wanted cheap energy we could use solar stills [motherearthnews.com] and run a 160-170 proof ethanol in our slightly modified E-85 cars and trucks.

      I do think ethanol from waste straw is a good idea but getting it from corn is also a good idea that could be even better.

  • could you use the stalks of corn and other agro waste to produce ethanol?

    and will this produce enough to increase the percent of ethanol in gas from 10% to 50% or more?

    if they can do that, and make it cheaper than a gallon of gas, then we should see a drop in energy prices.

    Because it doesn't provide enough biomass per acre. The more conventional crop to make ethanol out of is sugarcane. It *is* feasable to make ethanol out of high biomass crops like sugarcane.

        Sugarcane isn't the only crop which is feasable, there are several high biomass crops which thrive under differing conditions; Napier Grass, Leucaena, Eucalyptus, Sweet Sorghum is one of the more promising.

          Irony? Try, "luckily"... this just means that the land can be had cheap, or the people can be employed cheap, and either way it's more money to their community AND a lower cost of production. Which of course means that the ethanol will be cheaper in the end, meaning lower prices to the consumer.

          Hopefully, this will raise the locals out of poverty. If some of the richest areas were best for growing sugar cane, no one would ever be able to afford to grow the stuff in the first place.

    I, my father, and some of my closes friends have worked in ethanol production from food crops, and we have 2 observations to present.

    1. Farmers around the midwest are being paid not to raise crops. The crops they do raise are at times bought by the US and dumped at sea. Others are mixed with the maximum amount of dirt to make sure the maximum profit can be made on sales by weight & volume without violating health rules. From here, we can't see why there is any need to preserve food crops for "eatin'"

    2. Ethanol from corn uses as much energy to make as it provides when you burn it right now. Like any new effort the process is going to be inefficient at the start. As we continue to streamline the process, produce continuous flow rather than batch production, and become more selective in the corn we use, this problem should fade away.

      Let's see some links. Or did you just hear this from some guy?

      Oil companies do lots of research into natural gas and ethanol and the like because they know that one day, many many years from now, the oil production will not be able to meet demand. The company that can provide the fuel via another method will be the one making the profit. It just makes sense.

      Anyway, if you get a patent on something, it is made public knowledge, and it is available for public use by anyone after a few years. And, in the meantime, the knowledge is used to further the state of the art.

      So what you are saying is: Oil companies fund alternative fuel resource research and that knowledge is made public, furthering the state of the art and making us more independant from oil. They own the rights to the inventions for a while, but they make the invention public knowledge and the invention is released to the public after a period of time.

      Well, that sounds pretty reasonable! Maybe these companies aren't the evil entities the propaganda you listen to would leave you to believe? Maybe they are normal people, trying to make some money, and concerned about the future.

    This is really neither hear nor there. Nobody is thinking about using ethanol as a combustable fuel. It is just too expensive for that. One big reason for this is because ethanol needs to be very pure for combustion, the main thing being that it can't have any other liquids like water in it. So at present, it is only used as an additive to gasoline, because the blend results in cleaner exhaust.

    However making ethanol for fuel cells is something like 4x more efficient, because it doesn't have to be as pure.

    1. The research is not mature enough to be able to tell if ethanol produces more energy than it takes to produce it. People around here and in the media make blanket statements without any scientific research to back it up. All the reports I have seen don't even qualify where they stop and start measuring energy use for production. The fact remains that very little research has been performed on ethanol production when you compare it to the oil industry. Even if Ethanol doesn't produce as much enegy as it takes to produce right NOW..why not give it a chance an keep spending money on the research to maximize it. I've been around Ethanol production for the past 15 years. It has been bashed by the big fish for many years, because it was a threat. It has also been the victim of a monopoly (ADM).

Am I the only one that can see this? E85 fuel can be placed in the EXACT same fueling infrastructure that we have here in the US. This is the next step in my opinion.

      Big oil companies produce most of the ethanol used for fuel at least in the US . . . from crude oil sources as a byproduct. This will not cut our dependency on OPEC. If ethanol becomes a staple fuel, big oil can comvert refineries to maximize ethanol production and produce it in larger volumes and cheaper than bio-sources.

      Producing more energy than it takes to produce it is not the lynch-pin in the economics model. Right now, ethanol can be and is produced in chemical plants from crude oil sources for much cheaper than it can be produced from bio-sources. Purification of this byproduct is also cheaper because ethanol is slightly polar and most of the other things in the chemical soup at these plants are non-polar.

      Not true. Apparently you can't run the mix through long pipelines. Much of our fueling ifrastructure relies on these pipelines from the refineries to fueling depots where it is further distributed by truck.

      When sent through the pipelines, E85 tends to separate back out... It's only available near locations where the alcohol is produced and can be mixed directly.

        The separation occurs due to water contamination. When water content becomes to high, then the ethanol tends to separate from the gasoline. That is why you can't use the current pipelines without cleaning and retrofitting. Also, most modern day fueling stations use pumps that can handle the e85 fuel, they also use tanks that would need to be washed to be useful. Ethanol has different corrosive properties than gasoline. NOTE: If the equipment is rated to handle methanol, then it will handle ethanol with

    We are close to the point where we are using oil faster than we are discovering new supplies. The only direction for oil prices is up.

    Alternative energy sources are now becoming profitable. We are going to see a lot more of this kind of thing.

    My current favorite project converts turkey guts to oil. (www.changingworldtech.com) The latest I have heard is that they are now running a profit. They calculate that if America's agricultural WASTE could be converted to energy, there would be no need for oil imports.

    These are exciting times. Building 'refineries' all over the country to convert waste to oil will create many jobs. This will be a good thing for the economy. It will also be good for the environment. If we use biomass rather than dug-up oil, we will not be contributing new CO2 to the atmosphere.

    Anyone know if there is a cheap way to purify ethanol? Ethanol from biomass is essentially fermentation and the alcoholics ;-) in the crowd will know that typically it is hard to get fermentation to produce concentrations of alcohol above ~12%. This is because the fermenting bugs don't live well in liquid with high concentrations of sugar or alcohol.

    One must separate the water from the Ethanol to make it useful, this is typically done by distillation which uses nearly as much energy as the ethanol produced. What is worse is that Ethanol/Water is aziotropic. This means that when distilling ethanol from water, eventually the separation hits a stopping point at about 95% ethanol because the boiling points of water and ethanol in a mixture of 95%/10% ethanol/water are about the same. This is why the highest proof alcoholic drinks are typically 180-190 proof (as opposed to 200 proof which would be 100% Ethanol). Mass separating agents (nasty additives) have to be added to the ethanol/water mixture to elicit a near 100% separation. This makes purification even more expensive.

    Ethanol in gasoline is almost all chemical and refinery byproducts. Almost none is from bio sources because the chemical byproduct is so much cheaper than bio-fuel ethanol. In fact some alcohol produced at chemical plants is purified and sold for human consumption (it is added to some cheap gins). It's kinda weird to see a bonded and taxed tank of ethanol on a chemical plant site.

    Bio-produced ethanol often sounds good to politicians, but unless there is a new low energy water/ethanol separation process, it will never be economicall feasible on a large scale.

    I was reading here some mentions of how the US government pays farmers not to grow crops. I've heard of it before and I was wondering what the rationale is. I guess we'd have a huge surplus if everyone grew as much as they could all the time, but isn't it a little more complicated than that? If we used all of our land all the time, wouldn't we deplete it faster? I mean, doesn't the soil need time to regenerate? I know people want to grow food at full capacity and feed the world or make fuel or whatever, but is that really sustainable? What about all the petroleum products used to make the fertilizers to grow the crops? Does that get figured into the amount of net energy the ethanol provides?

    It's rare to HEAR about it. It's not rare for it to happen.

    Most media outlets aren't willing to say anything positive about capitalism, it undermines their agenda.

      No, the reason the media don't report it isn't their 'hatred of capitalism', it's because it isn't sensational enough. Bad things are sensational, whether it's US troops being shot up, princesses dying in Parisian road tunnels, or Democrat presidents playing around with interns. Companies investing money into research isn't news, it's business. Results get reported in the business news, they only reach the main news either when it goes wrong, or the

  • You have to dig around a bit on Iogen's site, but they do come up with *some* numbers. On their FAQ page [iogen.ca] they claim 300 liters per tonne of feedstock. Corn-based ethanol has a similar yield, though, and it yields more per acre than barley or wheat. (If my superficial googling is reliable, corn can yield 10 or more tons per acre compared to about 3 or 4 tons of straw.)

    This is fantastic if it reduces the cost of ethanol production, and allows it to be produced from straw that is currently just burned. But it won't make the gas industry obsolete.

    Novozymes from Denmark also develops these enzymes. Funny thing is the enzymes are first sold to liquor companies because they help them to get "cleaner" booze out of their raw materials. As price is much less an issue in that industry, the whiskey-boys end up paying for a large part of the devellopment costs. So think about it during your next tequila slammer: you are paving the way to a clean environment!
