A Japanese company has created the smallest and safest plastic-to-oil conversion machine:
Yeah technology!!! were saved.
Now we just need a DeLorian and a flux capacitor…
I’m skeptical of this video, plastic is made from more than just oil. Not to mention how overly simplistic this sounds. If it sounds too good to be true it probably is.
Thanks, Daniel. Awesome video. I have submitted this video to Digg.com.
David, I think there must be more to this as well. There is probably some other waste left over. Even so, it is still an amazing invention.
oil is BAD…this must be a fake..seriously
yeah oil is just terrible. you should definitely not eat anything that was grown due to reliance on oil, nor use electricity made from oil.
The problem I have is the part where he says, “this can be processed into gas, diesel, or kerosene,” without explaining that process at all. This machine isn’t useful if there’s nothing you can do with the oil product.
I want to think this will save energy and landfills, but I’m not sure. And I doubt it’s cost-effective.
How energy efficient is it?
The critical question is how much energy does it use per kilogram of plastic?
Anything Into Oil “Turkey guts, junked car parts, and even raw sewage go in one end of this plant, and black gold comes out the other end.” - Discover magazine, 2006
I doubt several of the claims made about the machine in the Japanese video.
First of all, it takes heat. He doesn’t say how much energy input in the form of heat is required. And a process that is heat-dependent is going to be much more efficient at a large scale plant than in a small home machine.
Second of all, he claims that this would somehow reduce carbon footprint. I don’t see that at all. Normally, that plastic would be buried in a landfill, i.e. the carbon would be sequestered. Turning it into oil instead, then burning that oil, releases the carbon back into the atmosphere. So if we use plastic-derived fuel to run vehicles, rather that fuel derived directly from oil, there is no difference in carbon footprint. The difference is in landfill-footprint. The only way to reduce carbon footprint from vehicle use is to drive less, or switch to smaller, more efficient vehicles.
I think the carbon footprint reduction he is talking about is that regions could be oil producers, rather than oil importers. By producing oil locally, you eliminate a massive supply chain that involves ships and trucks. So that would result in a reduction in carbon footprint if you didn’t need that.
However, I agree that there are a lot of unanswered questions here. I am guessing that there is some pretty nasty leftover slag from this process, and given the complex chemical compounds that go to make up plastic, that leftover slag is going to be highly toxic.
BTW, if you look into the “Anything from Oil” article and technology, their business model includes actually charging suppliers a fee to dispose of their unwanted refuse. That should tell you something about the questionable economic viability of the technology.
Keep in mind that most plastic garbage in japan is not put in landfills, but is burnt.
By-products of God’s amazing blessings to all of humanity! Now we can take those products and pollute the atmosphere even more than ever before.
You clearly do not understand the carbon cycle.
I think I’d rather see old plastic turned into composites that could be used for building materials, pipes, paving, etc. Still, anything that keeps plastics out of the ocean is probably a step in the right direction.
There’s no way to say that this machine reduces carbon emissions without telling us how much energy it uses. If you were to plug that thing into a wall virtually anywhere in the United States, you’d be powering it by burning coal; that’s a hell of a lot of CO2 right there, regardless of what the machine may “conserve”.
the big problem is that not all plastics are the same thing. They are made from polymers generated by breaking down oil. It does not use all of the oil which would be needed to restore it to oil that could be then processed into gasoline, diesel or kerosene. Also the liter of oil from one kg of plastic seems really improbable due to other things added to plastics. Several folks have also mentioned the question of how much energy is required. I think this is the new cold fusion – someone claims a miraculous and world changing discovery that evaporates when examined. He’s had his fifteen minutes, time to move on.
Pyrolysis. Not a new technology. As other posters have already commented, the video does not discuss how much energy it takes to do this. For all we know, it could take more energy to run the contraption than you get out of it. Also, no indication of hazardous off-gas from the process, nor how poluted the water in the vessel gets. I also doubt there is a 100% conversion, so there’s likely some nasty stuff left over in the heated chamber.
Nice idea as we transition away from fossil fuels, especially when our recycling industries are currently unable to deal with the large quantities of material recycled (ironic that in our throw away society, what little is recycled is too much…).
1kg of waste == 1l oil? More of a dream than reality I guess.
Listen – even if it takes more energy in than the potential energy in the product, it could still be used to, for example, turn the Pacific Gyre (the continent sized area of plastic in the Pacific) into a profitable resource by using solar energy to produce the heat and the resulting fuel as a way to store and release the energy – within an existing infrasructure. Tough to argue that finding a way to make cleaning up the gyres at all cost effective would be a bad thing.
So – the question is – what levels of pcb’s are produced? Could they be safely contained? Would doing this be at least as cost effective as drilling in the gulf? (Obviously, there would be no well to spill out of control.) What are the waste products? Considering that we collect, but don’t actually recycle tons of plastic water bottles – is this a feasible (and more profitable) alternative?
I tend to doubt these simple looking techno-fixes. If it works, why wouldn’t you go large-scale instead of making it into a Ronco Juicer?
The problem with the gyre plastic patches isn’t what to do with the plastic once you have it; the problem is collecting the plastic in the first place. At this point, for every kilo of plastic you collect from the gyre, you’re collecting ten kilos of ocean biomass. It makes removing the plastic from the gyre in the first place one of the biggest by-catch problems since dolphins in tuna nets.
What make me really worried about these magic solutions is that they end up amounting to nothing other then making people think that the magic solution is already here and therefore allow politicians to keep procrastinating on investing in alternative energy research since things are not that bad and we can keep going using oil made from bottle and ethanol made from food.
I have serious doubts.
Generally small scale is less efficient than large scale.
Why not solve land fill and energy issues like this:
(1) Sort the trash. Presorting prior to collection helps with this step. (2) Remove anything that can pay for its removal. (3) Remove anything else that makes problems for step 4 i.e. metals not recovered in step 2. (4) Burn the rest. Recover the energy as electric. (5) Ship ash to land fill.
In step 4 it is likely necessary to chop rubber tires into small pieces. Perform other pre burn prep as needed. Use the waste (pre smoke stack) heat to dry what is soon to be burned.
A well designed and operated municipal trash burner should not emit particulates or carbon monoxide.
The problem there is that you have a choice when burning carbon based materials. You will either get Carbon Dioxide or Carbon Monoxide. One of the reasons for the huge increase in CO2 output in developed countries is that we have spent half a century removing poisons from the exhausts of factories, power plants and motor vehicles, especially CO. Other pollutants such as SO2 can be removed by processing fuels but some form of carbon and oxygen is going to be released.
They are made from polymers generated by breaking down oil. It does not use all of the oil which would be needed to restore it to oil that could be then processed into gasoline, diesel or kerosene.
