MATERIALS REQUIRED

* 1 liter WVO (waste veg oil)
* 10 - 20 gr KOH (Potassium Hydroxide) or NaOH (Sodium Hydroxide)
* 220 ml Methanol

EQUIPMENT NEEDED

* 1x - 2 liter seal-able container
* 1x - measuring cup to measure out 220ml methanol
* 1x - scale to measure KOH or NaOH
* 1x - seal-able container to mix methoxide.
* 1x - funnel

THE TECHNIQUE OIL PREPERATION

* Filter WVO to remove junk and any solids.
* Heat WVO to 55deg C

MAKING THE METHOXIDE

* Do titration test for additional catalyst amount to use See: "Titration Test" for details

IF USING KOH: * Mix 220ml methanol and 7gr KOH + titration test amount to make methoxide. IF USING NaOH * Mix 220ml methanol and 5gr NaOH + titration test amount to make methoxide

* Stir or swirl to dissolve all, make sure it is completely dissolved.

NOTE: NaOH / KOH see "Adjust for Purity" article

MAKING THE BIO-DIESEL!

* Make sure WVO is about 55 deg C, using funnel pour into 2 liter container.
* Using same funnel slowly pour in methoxide mixture, replace container lid securely
* Shake the bottle hard for ten seconds
* Place the bottle on flat surface, observe the colour change, from light brown to dark brown.
* After 10 minutes the glycerin will start to settle and form a layer on the bottom
* After one hour, most of the glycerin will have settled
* You should now see a 2 distinctive layers, top is bio-diesel, bottom is glycerin.
* Bio-diesel will still be very cloudy and will take a day or more for it to clear

End of process, you know have unwashed Bio-Diesel

Proceed to "Wash 1 Liter" batch of bio-diesel
