small scale pyrolysis plant for making fuel

16/12/2017 at 19:20

Has anyone out there tried making a small scale pyrolysis plant for the really gross plastic and tires? I’ve been researching them a bit and it doesn’t seem too difficult, if anyone have experience with this process and has any pointers…

I’ve been watching this closely too.  PP user plaspod turned me on to the ‘Wastebot’ designed by Ben from Victory Gasworks.
he offers diy plans for $100 – to fund his further work with waste to fuels..
it’s a multimachine of sorts, using charcoal as both a heat source and a catalyst for breaking down long chains of plastic pyrolysis gases into their gaseous elemental form, that can later be burned for domestic heating or other light industrial processes.  Gases can otherwise be routed through condensing units for collection before reburn via the charcoal catalyst.
true regulations are likely a nightmare with this – but this represents a kind of tech that seems feasible only when small
Our crew just wrapped up building what he calls the diy model – to date we’ve had 3 runs on it, mostly successful.  This thing is great for dealing with hard to remove sticky paper labels, waste bits from PP processes that can’t be re-shredded, or some of the food waste covered plastics that are too gross to bother washing.   For our last run we used 9 lbs of charcoal to gasify 5 lbs of these dirty plastics (no pvc, #7’s)  in about 1.5 hrs.  These aren’t impressive numbers… but we’re getting there.
with some dedication to our local scrapyard I’ve got less than $800 US at this point

I’ve been on the energetic forum for some time, long before joining here.
The pyrolysis of plastic has been of interest to me due to the fuel produced being a valuble resource, for deprived communites.

Most things can be pyrolised, tires, waste oil and grease, and in our case waste plastic.  except PVC, PET, ABS.
PVC gives off clorine gas,  Which might be mitigated by the addition of an alkaline to the bubbler water.  Would need to be tested.
PET Leaves behind a residue in the pipes, reducing internal diameter, increasing pressure, and in extreme cases may cause explosion.
ABS is nasty and pollut’s the bubbler water, to the extent that it’s disposal becomes a problem.

If you want to discuss this, you can probably find me here.

I tend to have it running most of the time.
