permaculture

[Koreen Brennan <cory8570@yahoo.com>]

It might be cheaper energy wise and financially to just burn the plastic and 
convert to electricity, like a number of waste to energy plants are doing 
currently. I couldn't find anything conclusive but it looks like this method 
might use more oil through the heating and conversion process than it 
creates.

I doubt that it is a hoax, it seems plausible to me.

But I also think there is less there than the video implies.

At every step of this process --

+ pumping and transporting crude oil,
+ refining it into plastic feedstocks,
+ making plastic,
+ shipping/manufacturing/distributing
+ collecting the trash
+ converting it back into oil

energy is lost.  The final liter of oil that comes out of 2.2 kilograms 
of plastic trash embodies quite a bit more energy in its processing.

So it is a way to extract one final bit of embodied energy and maybe to 
process large amount of plastic trash that presently contaminates the 
biosphere.

The video doesn't say anything about any possible residue that might be 
left over after the conversion. Maybe there isn't any.

The best solution to plastic is to stop making it, and eventually that 
will happen.  We would have to think about this proposal and examine its 
ramification as a way to rid ourselves of the terrible plague of plastic 
trash.

Pitty that burning plastic produces loads of dioxin, one of the most toxic
chemicals yet made by man.
