    Hello all, finally started my unit

    Here are some pics of the beginnings of my unit. Unfortunately I missed Jetijs presentation of what plastics yield and types. I would be very interested in seeing it. If its at all possible I would appreciate it very much. I own a metal recycling facility just outside of Ottawa Ontario Canada. Anyone from this area should be able to figure out who I am just by looking at my user name but if you would like to email me that's fine too. My email is ed.carron@yahoo.ca the pictures you are looking at are of a prototype unit. Once I have experimented enough I will be using a 1000 lbs propane tank stood up. I plan to heat it with 4-6 gun burners from furnaces and use the oil produced as fuel. I would like to know if anyone near me is attempting these projects as I have almost 60 acres of equipment to harvest parts from and literally 1000's of tons of steel to work with. Anyway a big thanks to everyone on here who contributes and keep up the excellent work. image.jpg

    Hi everyone

    I'm new to this site but have been checking out this thread for a while now, I too am interested in recovering liquid fuel like gasoline or desile from plastics, but I am also currently interested in recovering copper from computer components and was thinking this would be a great way to dispose of the plastic waste that will accumulate.

    I was wondering what will happen or what should I do regarding Brominated flame retardant found in most computer plastics. Will it be an issue or what kind of damage can it cause the environment. I am already taking precautions regarding mercury and other dangerous chemicals and am seperating them out before this stage but I was wondering what to do about the flame retardants found in the plastic.

    @Beyond biodiesel:

    Thanks for the information about the band heaters.

    I looked on google for band heaters but it seems they only have small ones for extruders. I think i need a very big one for a 1000 liter reactor.(big diameter)

    If i use a band heater then i have the perfect insulation in a store nearby.

    I will be done for about €200. its white and used by proffesionals who make chimneys.

    We used this on the injection moulding machines. the barrel was around 200celsius and after insulation you could put your hands on this.

    Next week my plans are to ask my brother to make a nice 3d drawing of my ideas of the installation. Find some nice parts on the internet with the prices and share this here so we can discuss this.

    Lets go easy and use 1kg of your product, since your BHT is in kg, thats 1000g's so 1000 x 0.0050 = 5 grams , hence 200 parts will be 20 grams and 500 parts will be 50grams of BHT.

    IF you insist to work in Litres you will need your specific gravity, lets assume diesel is 0.86 then simply for 1000ml (1L) you will need 5 grams x 0.86 = 4.3 grams of BHT for 1L of your product.

    Regards
    Thanks AAS,

    the explanation is clear and very valuable to this forum. Will update when i have done another run and conducted the trials with BHT. Maybe sometime next week.

    One could just lift the hose out of the bubbler as soon as the heat is cut. Otherwise, if the retort did not have thick walls, then the vacuum formed would collapse the retort.

    Thank-you AAS, for providing valuable information about reducing polymerization, which is new material for us all here.

    This is the difficult part because normally these machines are driven by hydraulic engines. around 150 to 300 rpm.

    As i already explained i have a recycling company and i have a few granulators and shredders.

    I would like to ask AAS if he can make a detailed photoshoot of his installation.

    I have my eye now on a used ceramic oven of 70 Liters. It only costs €150.
    Chris, I find band heaters are much more efficient for heating a retort with, because they rely upon conduction; verses kiln heaters rely upon radiant heat, which is far less efficient for heat transference.

    However, the insulating material that comes with the kiln, if it is the right size to surround your retort, would be very valuable, because fire brick and kaowool are quite expensive.

    You could also recycle ash and crushed glass into making your own fire bricks.

    I agree, the extruder is a good idea. They are fitted with heaters along the length of the screw. They will be 3phase I believe. So look for redundant equipment where plastic is injection molded or blow molded. Also a granulator from this industry is of the right quality to handle the task of chipping the waste raw material.

    See this animated video of a commercial plant for some ideas. This is gas fired but worth a look.

    Getting people to agree on anything can be a challenge. Perhaps look at all design ideas presented and then cherry pick the pieces you like.

    Need some help:

    1.I have found some BHT Food grade available, has anyone tried this or i need to use some other BHT for Industrial or specifically for petroleum industry?

    2. In what proportion should i add the BHT to the produced fuel? 1Kg to how many liters,etc?

    Please help, i need to deal with stability of produced fuel.

    Ofcourse i don't want to make the mistakes that beginners have.

    I think this thread is meant to be a lesson for anyone who is interested and so they dont have begin all the way from the start.

    Thats why i suggested to make a drawing.
    everytime someone makes a improvement and everyone agrees, there will be a next edition of the drawing. (Any volunteers who can make technical drawings?)

    In the end we should have a perfect working machine with no dangerous situations.

    Ofcourse there has to be some extra safeties buildt in.

    Is this a good idea or am i asking too much for a beginner on this forum?

    I did not read all of the 107 pages but i think i know most of the important stuff.

    I have a small recycling company where i shred plastics. (regrind)

    Now i want to make a plastic to fuel machine.

    The problem is.. i dont want to lose time and money on a small device like 20 liters.

    I´m thinking more like the device of AAS.

    Is it not a possibility that we make a parts list and some drawings so people can build something what works with the right materials?


    Can you give me some good advice what i should do?

    Thank you,

    Gr. Chris
    Welcome Chris, building a pilot plant is a necessary developmental process for each and everyone who wishes to design and build a pyrolysis unit, because in a pilot plant you can make lots of mistakes without killing a lot of people.

    And i would like to have an automatic feed for plastic and maybe also automatic char removal. (Sorry for my bad english)

    I was thinking to use an old extruder from an injection moulding machine to preheat the plastic and to inject it into the reactor.

    Can someone explain the different types of metal because in Holland i think they use other names for this?
    Using an old extruder from an injection molding machine to preheat the plastic and to inject it into the reactor sounds like an excellent idea. We should all go looking for such a device.

    What you have thought about pre heating in extruder is very correct idea . You are on right track .

    First i thought iT would be a good idea to use the fuel and gas for heating the device. But after some Reading electric heating looks better.
    Its not so expensive as i thought it would be.
    Also it works cleaner i guess.

    I have a very big power supply, so that won't be an issue.
