How to turn plastic waste into diesel fuel cheaply

[dedooo]

I have a question what would happen if we made the valve after the reactor 'and closes after the completion of the pyrolysis process' in order to prevent the return of air conditioning or sparkling water to cool down and twisted' then we can open it safely

[Chris@NL]

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 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.

Hi All,

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.

50 ppm 0.0050%
200 ppm 0.0200%
500 ppm 0.0500%

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

I have already have one extruder wich i can use. It only needs a electric motor.
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.

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.

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.

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.

@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.

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.

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

I found band heaters that were designed to fit around a 200L drum. Often band heaters can be linked back to front to make them go around a larger diameter. Any size can be ordered though from the makers.

Welcome curlyrocks, I have not looked into the pyrolysis of Brominated plastics, so I am not sure what you will end up with, but other haulogenated hydrocarbons tend to produce toxic byproducts, and poor quality fuels.

Welcome, EdCarron, nice work, decent flange, very good. Your retort should work great as long as you get your heating and insulation right, then condensers, and a water trap, and you are good to go.

How to turn plastic waste into diesel fuel cheaply

Hello
Thanks for sharing information.

Well I want to know little more about the effects and problems occurs by the process.

Is it Eco-friendly to Environment?

I want to know when we heat plastic its convert to vapor, When it converts to vapor is there any bad smell release from it?

I want to install such plant in residential area is there any side effect?

[Beyond Biodiesel]

Welcome, syed722, if you stay away from cracking halogenated hydrocarbons, and you develop an efficient condenser system, and use a water bubbler and a burner to burn anything that makes it past your bubbler, then the exhaust should be only CO2.

On the other hand heating any flammable hydrocarbon up to 400c in sufficient quantities to make it useful for fuel making, then that is going to be a potentially hazardous situation with the possibility of fire or explosion.

[Excalibur]

The process is a good form of recycling waste material into usable fuel which would otherwise fill dumpsites or pollute land and waterways. With proper controls and good practices, the effects can be contained or eliminated.

Yes, if you were to sniff the vapor, you'd declare the smell as very bad but this vapor gets condensed into liquid and any non-condensable gases are best incinerated. Otherwise I thought those gases could be captured and stored for later use. Either way don't simply vent the gases to atmosphere.

As for side effects, much of the dangers can be controlled with good engineering of the equipment. A pyrolysis plant has the potential to become a large fireball if a leak met an ignition source with oxygen. Then a situation would get out of control with no way of stopping it. I suggest position the unit well away from buildings.

Hello All

I have design one Plant.

Can anyone help me in finalizing the design?
