Sounds to me like a very good proposition to convert plastic waste into a high quality and valuable fuel.

>>Commonly used to make a wide variety of items, low-density polyethylene can be recycled into new plastic, but there’s much more waste than recycling facilities can currently handle. With that in mind, scientists have now devised a method of converting the material into something else – jet fuel.

Led by Assoc. Prof. Hanwu Lei, a team at Washington State University started with low-density polyethylene waste obtained from sources such as plastic bags, milk cartons and water bottles. They then ground that plastic into granules measuring approximately 3 mm across, or approximately the size of a grain of rice.

Those granules were then placed inside of what’s known as a tube reactor, on top of a bed of activated carbon. The plastic and carbon were subsequently heated to a range of 430 to 571 ºC (806 to 1,060 ºF), resulting in a thermal decomposition process called pyrolysis. With the carbon acting as a catalyst, this caused the plastic to break down and release its stored hydrogen content.<<

sounds like a similar process to making biochar.

See Good Scientist cartoons on this topic.

It’s not true of course, it should be “heat and natural gas turn plastic waste into jet fuel”.

Ok. I’ll read the link later. I like the idea.

it would be good if old tyres could be recycled in a similar way.

Also, I would have to question the need for jet fuel (presumably they mean alkanes with carbon chain of between 12-16?) specifically. A gas turbine power plant could use a wider variety of fuel than just this.

Wouldn’t jet fuel be quite useful for fueling jets?

You mean aeroplane jet engines? Yes, but presumably the level of purity and refinement required for that would be greater than running a power station. A gas turbine in a power station is very similar to an aircraft jet engine, but usually they can run on a wider variety of fuels.

I think I read something about that the other day – a pilot plant in regional NSW.

Yep, out the back near some shit hole ..

my optus internet bill came today and apparently this service has been disconnected because of the nbn.
i’m listening to fugue while waiting to talk to carbon based unit.

You’re right. They are after C9 to C16, which is what they refer to as jet fuel plus diesel fuel.

So they produce C9 to C16 plus biochar. The biochar adds to the activated carbon.
