Bridges and Real Estate

[doo_much]

I think we need a new thread

i was pondering that very thing this morning...

Indeed it seems we does.

Although some of the stuff we lol about might turn out to be viable?

Anywhooo.

I'll kick off:

A Fil­ipino inven­tor has found a way to con­vert plas­tic trash into fuel – Gaso­line, Diesel and Kerosene. Though not a very new inven­tion, Jayme Navarro has found his own way of turn­ing plas­tic into fuel, through a process called “Pyrol­y­sis”. This patented sys­tem has been proven to con­vert non-biodegradable and non-recyclable plas­tics into fuel. If imple­mented in a large-scale this sys­tem could lit­er­ally turn hill sized land fills in the Philip­pines into a gold­mine – “fuelmine”.

Now I don't know much chemistry, but this seems to good to be true?

And no, this is not the same Filipino who claimed to have invented a water-fuelled car.

Whats with the odd thread title?

[doo_much]

Never heard of people selling bridges and real estate in marshlands?

Yes, indeed we does

Nope. But I get the idea for the thread, still a little vague though.

I am no chemist but isn't plastic made from oil/petroleum? So if you melt it down and can make a engine run on it with its extra additives that would be a win. Just dont see it as being plausible...

We need input from Cap I think. He works for SASOL and should have a valid opinion?

And as for the title - read here and here.

Well, technically it's all just carbon, hydrogen and oxygen. I'm not so sure though how you get them in the right compositions- you might as well end up with sugar
And what about fuel quality?

According to the article they just boil/cook the mush and then condense the fumes?

i'm still not sold on the commercial viability... it would require a fair amount of power...

unless they're feeding some of the recovered fuel back into the system?

and pyroly­sis is how charcoal is produced... the use of the word hints at woo...

<edit>or not much energy at all

The actual energy consumption for cracking and vaporizing PE into fuels is 1.328 MJ/kg which is less than 3% of the calorific value of the pyrolysis products

- so, very possible...

Hmmm - well spotted Rusty.

"pyrolysis: chemically decomposing organic materials by heat in the absence of oxygen"

And as for the title - read here and here.

As long as it makes sense to you.

Thanks.

So rusty - you think it's feasible? So not a 'bridge' then?
