Not really earthshattering. How much energy goes into the process for what return?
Read the note at the bottom of the article..
I am sorry, but I must close this thread and kill anyone who read it.
Can't get the video to work, but I'm very interested.
Okay, Now that just MAY be worth it!
Seems to me that it is being promoted as a way to recycle plastic, not as a replacement for "traditional" oil.
I'm on a phone and the page is not loading well.
We make plastic FROM oil, so it's not much of a surprise that someone figured out how to convert it back. It's a good idea and it will help, but it's hardly a panacea.
The machine costs almost ten grand. I'd like to see what could be done using a large pressure cooker. It seems that's all it is, really. Except the steam escapes down a tube and into a vat of tap water, where it is cooled and thus oil collects at the bottom of the water vat. However, it looks to be some pretty high temps to get the plastic to this point (read: really dangerous).
Basically 2 pounds of plastic garbage can be turned into a liter of light crude. From there I would assume the oil could then be transesterfied into diesel.
That doesn't sound right. I find it hard to believe he is getting 1.9 pounds of crude out of 2 pounds of plastic.
I'd be a lot more impressed if someone figured out how to make decent plastics out of something other than oil, like lawn clippings & tree leaves - then we wouldn't use so much oil for that in the first place.
Converting oil to plastic and back to oil just sounds like a waste of energy to me.
The waste of energy is just throwing the plastic into the landfill, why not turn it into something?
Not sure on the weight of one liter of light crude.
Again, I would like to see what could be done with a modified pressure cooker. What kind of temps, specifically, are we talking about here.
Because it takes more energy to turn it into oil then you get from the amount of oil the process would yield. You have a net energy loss in the whole transaction. You would be better off just keeping the energy you had to begin with.
While this might help with landfill usage, it does nothing to help our energy needs (in fact it makes it worse).
I swipe plastic into pump at 7-11 and gasoline comes out.
Organic chemist here. I would need to know what the conditions inside his reactor are, but I think this guy is seriously over simplifying and over stating his case. The products you obtain will depend heavily on the type of plastic you use. You're not going to get gasoline from polycarbonate, say. It's not going to be turned into the same composition of crude out of the ground. I think he also said that you get a lot less CO2 burning his "oil" product than you would burning the plastic starting material, and that doesn't seem to make sense either.
I believe he was referencing getting rid of the waste- it could be burned (which is what they do with plastic in Japan) or it could be "melted" down and returned to it's natural state (no CO2 byproduct of melting).
All he is saying is that if you melt the plastic down *enough* you will get it's basic composition, which is light crude, which can then be refined into gasoline or diesel or petroleum jelly or whatever your little heart desires.
I also want to know what the conditions inside the vessel are. I can walk to the cemetery down the road (1/4 mile) and pick up two pounds of plastic garbage no problem. If it can be done, I want to learn how to do it.
As for the plastics involved, supposedly it can use polypropylene (PP), polyethylene (PE) and polystyrene (PS). Your typical consumer-trash plastic, no?
simpler and takes less energy to convert plastic to plastic.
