Welcome - Collaborative Biodiesel Tutorial Website


Basically, you make a 20% methanol 80% used cooking oil mix.

Heat oil to 120* in old h20 heater and add lye/methanol mix.

Titrating Oil - Collaborative Biodiesel Tutorial

This removes the glycerin from the mix to keep it from congealing.

The 120* mix is then pumped into another drum and is left to separate. (24hrs)

This drum has a spout on the bottom to remove glycerin and one a few inches up on the side to drain the bio.

Remove all glycerin. Add water to the oil/methanol mix. Remove water. This will clean the fuel. (2hrs)

You can repeat the water steps as many times as would you like.

You are now ready to go!!!!

I use this site for specifics:

It is really that easy. Although a drum of methanol is getting pretty expensive.

$190. USD = 55 gals of methanol

Very Nice. My biodiesel lab is close to running but its too cold to run now. My exhaust should smell like the local fish fry.

Just curious what you are using the glycerin for?

I'm hoping to have space and time to set one of these up myself. I've heard there is some smell (stench) that goes with processing the mix. If so, how smelly is it=?. Will I get complaints from my neighbors, or just my dog?

Not smelly at all.......

System is sealed.

You don't smell the oil during the refining process.

No complaints yet.

My dog is always whining when food is around

I am extracting it from the cooking oil.

Need some?

Glycerin + Lye = Soap

IIRC, Glycerin by itself is an excellent degreaser...

Free bump for currious minds.

Yes it's an old post. Thanks for the bump, rekindled my interest.

Now if only I knew where to get Methanol in "La Belle Province"... "Je me souviens" pas pourquoi on ne peut pas en trouver (I can't remember why we can't get any here, been told "it's illegal to buy or trasnport without a hazardous chemicals permit"...

How do the backyard biodieselers do it?
