Transforming Waste Plastic Into $10/Barrel Fuel

Mike writes "Today Washington DC-based company Envion opened a $5 million dollar facility that they claim will be able to efficiently transform plastic waste into a source of oil-like fuel. The technology uses infra-red energy to remove hydrocarbons from plastic without the use of a catalyst, transforming 82% of the original plastic material into fuel. According to Envion, the resulting fuel can then be blended with other components, providing a source for gasoline or diesel at as low as $10 per barrel."

    For most plastics, the making is energetically favourable. That's a fact. You often will have to heat up the monomer mix, and usually add a catalyst to help the reaction, but the reaction itself should be producing energy, not consuming it.

    Cracking the plastics back to oil-type chunks does need a bit of energy to be added.

    And finally to put things into perspective (as you obviously know nothing about the chemistry of plastics), the amounts of energy involved in these reactions are nothing compared to the energy released when burning the oil/plastics. Plastic itself is a fantastic fuel, it's just impractical to use as is in internal combustion engines.

    On the envion.com web site, PVC is mentioned as one of the major components of their feed stock. This indeed surprised me, you are right, the chlorine is an issue. If burned it may produce dioxins (very very poisonous stuff), or hydrochloric acid that wreaks havoc on any metal parts it comes in contact with, such as the internals of your engine.

    Either they have a way to remove the chlorine later, or they take care of it in another way - this is not mentioned on the web site. At least I couldn't find it. If there is really chlorine in the product then I'd not want to use it at all. And I also doubt it could pass any environmental standards when used in engines due to the dioxin problem.

    The chlorine will not be "liberated" to Cl2 as it is not chemically stable in this case. As soon as there would be a Cl2 molecule in the mix, and it finds a hydrocarbon with a double bond, it will react with this hydrocarbon. And double bonds there will be plenty of considering it is a cracking process. So no chance to get Cl2 gas out of it without taking special measures beyond just thermal cracking of the plastic.

    Your contradicting yourself, if it is energetically favorable then no catalyst should be necessary because a catalyst is used to circumvent a difficult step in the making process which would normally not accure. While this company claims they have found a way to use IR to deteriorate plastic back to oil-like products without a catalyst. And this is seen (more or less) over long periodes of time in nature itself for some plastics. So it's not completely nonsens.

    And you obviously don't know what a catalyst is doing really.

    A catalyst will never, ever make a reaction go the other way than it would naturally do. What a catalyst is doing, is lowering the energy barrier for a reaction to take place, increasing the speed of a reaction. In some cases without a catalyst the energy barrier is so high that a reaction would be so slow that it basically does not occur.

    You can however change the favourable end products by increasing the temperature - in the extreme, when temperature is high enough, all atoms will break bonds with each other and go free. This is what is done in oil cracking: heat it up, so smaller molecules are more favourable than larger molecules in terms of energy and entropy.

    Another way to crack molecules is to use radiation like IR. IR with the correct wavelength will energise and resonate the bonds of molecules to the point of breaking, thereby cracking the molecules. Again a catalyst can help in this process, lowering the energy required to get enough resonance to break a bond. As the reaction takes place inside the molecule there may be not much a catalyst can do in this case, or the reaction is fast enough by itself that adding a catalyst is not helping enough to justify the cost.

    The energy barrier to re-make the bond is at low temperatures so high that it can not be formed anymore. That is why ethylene gas is stable, and will not spontaneously polymerise to polyethylene. This in contrast to e.g. styrene or terephtalates which do tend to polymerise over time when stored at room temperature.

    The law of conservation of energy only applies to a closed system. This isn't a closed system.

    The plastic feedstock contains vast amounts of energy, where the point of the process is to change it from a solid to a liquid that can be used in vehicles. Since we've established that the feedstock contains a vast amount of energy, it's only reasonable that some of that energy can be burned to power the process of converting from a solid to a liquid.

    Make plastic into other plastics (recycle!)

    That sounds good, but isn't 100% efficient either. Many kinds of plastic have no recycling market because it's hard to reconstitute it into high-quality material. So what you often get is the recycling center wasting resources on sorting out certain plastic types then dumping them in a landfill.

    Moreover, a lot of other plastics are only turned into low-grade products. Take plastic decking boards. How many gallons of oil are tied up into just one of those huge solid chunks of junk plastic? Will that in turn get recycled again? Doubtful, because they usually mix in non-plastic fibers to give it what little strength it has. All that petroleum will probably get pitched in a landfill after the single recycling pass.

    As long as anybody in the world is burning oil as fuel, it makes just as much sense to get the oil from junk plastic as from direct crude oil. If you want to complain about using petroleum, you need to *first* get all fuel use eliminated, *then* you can worry about plastic recycling. You're putting the cart before the horse.
