I'm a chemist and still unimpressed.

Yes, I see that but the quantity of vegetable oil is not going to replace
conventional fuel because there isn't enough of it. Ergo, no substitute. A good
idea to replace a *small* amount of fossil fuel though. It all helps.
I doubt the use of microwaves has any beneficial effect because it's a
*chemical* process. Well known and understood for a decade or more.

So how much chip fat oil is he planning to produce ? There's a very limited
source.
Old 'news'. Try again. People have been turning used vegetable oil into a diesel
substitute for decades now. Yes, it can re-cycle what would otherwise be waste (
and is
sensible if you have a suitable source ) but there's not enough of it to make a
significant impact on total fuel usage.

There are many uses for glycerine, including explosives. Dynamite is
nitroglycerine and a binder. Most smokeless gunpowder contains a
substantial percentage of nitroglycerine, in the range of 20%.
Glycerine also can be used to manufacture alkyd (ALCohol/anhYDride)
resins for paints. Besides soap, glycerine is used in emollients and
cosmetics. In consumables, glycerine is used to make distilled spirits
taste smoother.

Well they think too much is made for the demand.
