Open source plastic pyrolysis machine

30/12/2019 at 08:11

I read many articles about converting plastic back to usable fuel using pyrolysis technique. But there are no solid building block for any one about how to setup a pyrolysis plant. I’m searching for a viable open source schematic to build a working model. If i got any, i’ll post on this forum. Here is an example for desktop model of working pyrolysis machine.

Thanks for posting the link. It is an interesting price point. At $4K it is similar to a suite of PP machines. For some people a turn-key system is probably the safest way to go. It would be nice if the site had some basic technical data.

The Precious Plastic approach works well for marked PE and PP but for everything else more work is needed and pyrolysis may be the answer for some of it.

Yes, please post what you find

I thought that this was a good overview.

Everything is about economics of scale.

If you observe the desktop machine in provided link, you can observe that there are clamps in between each condenser. I doubt that there should be a bubble cap like mechanism held inside the clamp. just like a vertical fractionating column but in horizontal alignment.

Plastic Odyssey (https://plasticodyssey.org/en/)Β is working on an open source unit.

@griffinf3 hey πŸ™‚
this comment might be a bit off-topic but worth knowing

they (PlasticOdyssey) are also fully appropriating themselves all the work made by PreciousPlastic :/

Yeah, a TED talk without any T content is yet another “raising awareness” fundraising exercise. To be open source they probably should post some design information for the pyrolysis machine they built. Not sure why they need to shred the plastic though.

For the price of the voyage they could probably build a thousand units and get them in peoples hands. But, hey if you can get sponsors, a voyage is better PR.

@jamyb , well said. if we made small contribution in the way of research towards providing an open source model to make fuel from waste plastic, it would revolutionize the lives of millions of people who still don’t have access to electricity, cooking gas. This would indirectly cleanse already disturbed ecosystem.

Probably this document may help to build a machine..

@kiranmantha , Thank you, that is a good paper. It does suggest that this would not be a casual build to make it safe and efficient. It seems to me that it would be an ideal project for a university to produce a well engineered small scale device and put it in the public domain. Did you see the Dung Beetle project link in this thread?

that’s really an interesting project. the plant is compact and more interestingly it is mobile πŸ˜€
