Make Your Own Biodiesel
Interesting. Could be useful to know I guess. Probably not something I'm going to try.

Major problem with making bio is that you end up with some waste (glycerin) you have to do something with. Who takes glycerin? |

Like I said, I'm going to be looking seriously at.
From the above site:
Reclaimed glycerine can be composted after being vented for three weeks to allow residual methanol to evaporate off or after heating it to 150 deg F (66 deg C) to boil off any methanol content (the boiling point of methanol is 148.5 deg F, 64.7 deg C). The excess methanol can be recovered for re-use when boiled off if you run the vapors through a condenser.
Another way of disposing of the glycerine, though a great bit more complicated, would be to separate its components, mostly methanol, pure glycerine (a valuable product for medicines, tinctures, hand lotions, dried plant arrangements and many other uses -- see Glycerine) and wax. This is often accomplished by distilling it, but glycerine has a high boiling point even under high vacuum so this method is difficult. |
