Plastic to diesel machines
« on: March 02, 2017, 11:02:40 am »
Or on a larger scale also called plastic pyrolysis plant.  It can turn plastic into a burnable oil that can be mixed with diesel or into diesel.

Many news article around about people building and selling such machines in South Africa but yet I don't see any stories about people making a business out of a machine they bought. Why?

I know a WD who has been struggling to make those.  Problem is the diesel is inconsistent.  It is ok for old fashioned stationary diesel engines - those single cylinder electric generators (Perkins?  I forget the common ones name).  Often good enough for diesel engines with traditional diesel injector pumps - diesel bakkies.  Very unlikely to be good enough for current pressure rail systems.

I have been looking to buy bio/recycled diesel  for some time, as I run an old  diesel  lister engine for power, and an old tractor which has a Perkins engine on the farm, and even a land cruiser which will run on such crude fuels, but it is completely unobtainable commercially as far as I can figure.. If someone knows of where I can go and buy say 1000l at a time, please let me know.

i am busy with one of the dogs on the forum who is busy refining the process and machine to produce this diesel. have just got the go ahead to start making the burner and all the steel work. biggest problem, as i understand it, was getting the process right so that it did not produce wax. he runs his old Mercedes on it with no issues. he has a test plant running.
i only work to support my hobbies!!

Seems there are many building such machines and even some selling them yet as DB9 noted no product available to buy?

Is it purely due to the quality being that bad? Even for farm use like in lister engines or old tractors?

Correct me if I'm wrong but doesn't it take more power to convert plastic to diesel that you get out of the fuel?

I have produced ester( biodiesel) for about 5 years and of good enough quality to run my cdi vito on it, said vehicle is still on original motor.
Out of my experience, the effort you have to put in to make good and effective alternate fuel in most cases is not worth the saving made.
I am looking at putting up my plant again and also looking at the plastic as I have the base material available.
I cannot see it working except if you do the whole lot together.

As I understand the plant should be able to run on the product it produces requiring no external input. Apart from startup. Efficiency of the design is obviously important.

Thanks, so there is a lot of effort involved?  They all make it seem like an easy process: Throw in shredded plastic, turn on and get diesel.

Read an article which they used the process to make an oil (from tyres though) and mixed it with diesel which they claimed improve the diesel.

Did you build your own machine or buy one?
A picture maybe?

Yip interesting

With his cheap machine he only saves 10-15%. Does not sound worth the effort. Wonder what makes it so expensive.

And then the diesel/petrol produced varies from batch to batch and you don't really know what you got.

Built my own, it is not very complicated, but I have mine all stripped down in pieces from when I left the farm.
I use a sentrifical to remove the last water and solids, that alone will set you back over R100 000 so there goes the economy of scale.
