(1) Ratcheting Crimper for use with 15/30/45 Amp Powerpole Connectors

Parts
(1) 800GPH Pond Pump

Sourcing Notes
Any inline or sump pump should work for this. The more control you have over flow rate, the more control you have over the water-cooling of the towers, so finding one that can be modulated is smart. This one is cheap and should work.

(1-6) 1/2-Inch Diameter Stainless Steel CSST connector, 24-Inch Length

Sourcing Notes
These are made for connecting gas appliances to gas lines. They are stainless steel and work well as condensers. I used these to build the final down-tubing for the condenser. You can splice multiple lengths together with Tee fittings, and capture they liquids that way, as an addition to or alternative to using the expensive dephlegmators.

Optional- (1) PID Charcoal Blower

Sourcing Notes
This bit is optional, and I didn’t use one, but I would if I could do it again. These are made for temperature-control of smokers. They have a little thermometer, and temp controller, and they blow a variable amount of air onto charcoal in order to increase the temps. The presets are in the 300-400F range, which is low for pyrolysis, but you can just put the temp probe further up the stack until it maintains the temp you want. In the future I want to add open source control of this, but for now this is a ready-made solution.

(1-6) 1/6th Barrel Sanke Keg

Sourcing Notes
Don’t buy these new. You can find them on craigslist; I just asked my FB freinds and got 5 of them. One is required, more enable you to fill one while another is firing, and switch them out like fuel cartridges.

ALT OPTION- (2-4) 1.5″ Tri-Clamp Condenser

Sourcing Notes
You can get these much cheaper at AliExpress.. I did not use these exact ones (I used 2″), but I would if I could do it again, because they are cheaper, simpler, and less tall than the ones I used, allowing you to add additional distillation stages, for greater control of distillation and temperature.

(2) 1″ diameter 300W Heater Bands

Sourcing Notes
These are the ones I used, Amazon seems to be out of stock. You can also take the band-heater element out of most “crockpot” style warmers, and wrap it around the barrel. The PID will take care of the rest.

(1) Char-Broil Propane Turkey Fryer

Sourcing Notes
Found mine for $10 at Goodwill. The fryer adds structure to hold the charcoal, keeps heat focused on the keg, while also giving you decent low-temp control. Comes set up with a propane burner that can be used to retort the syngas for making biochar.

(1) 4:1 Planetary Geared NEMA24 Stepper Motor

Sourcing Notes
This is the most expensive part of the extruder, but it’s the best way I’ve found to get sufficient torque for extrusion AND precise computer control. Open to suggestions and improvements, but this works.

(1) Lava-Style patio heater

Sourcing Notes
The glass tubes on these particular heaters tend to break, check craigslist for used cheap ones before buying new.

(1) Inverter-type generator

Sourcing Notes
I’ve succesfully run one of these generators with Syngas from the Metabolizer, and it produced 60hz/120VAC, under no load. Have not tried again, but results are promising. Other inverter generators can also likely work. If you buy from Harbor Freight locally (not amazon) you can get a basically-unconditional warrantee, which I recommend doing.

(2) Dahl 1/2″ Dual Hose Drain Valve

Sourcing Notes
I got these to control with servos, but I switched to cheaper ones for that. These are still good for fine control of gas flow, and I use them to control the gas going into the engine.

(1) 2-1/2″ x 10′ Ultra-Flex Clear PVC Hose

Sourcing Notes
This is for delivering the shredded plastic flakes to the extruder via vacuum line. Clear tubing isn’t strictly necessary, but it’s very helpful to make sure material is flowing properly.

(1) Stainless Steel 6 inch x 1.5 inch Tri-Clamp Ferrule Flange

I found that 1.5″ Tri-Clamp pipes fit perfectly inside the neck of the keg, which makes a better seal than 2″

(2) 1/2″ Stainless Steel Mini Ball Valve NPT FxM Thread
