Dear Agnes David House advocates putting it into a biogas digester for a high gas yield. Says it is wonderful stuff.

Dear AD, yes, it can be re-used, but the question is, how often can you do that and what happens with it afterwards; is it thrown away then, fed to the pigs, or could it be filtered and used as a fuel?

November 2011 16:32 An: Discussion of biomass cooking stoves Betreff: Re: [Stoves] Vegetable oil or biodiesel? Dear Richard, vegetable oil is used in India mainly as a medium for frying. One uses the left over oil again for the next batch to be fried. Throwing away used edible oil is not a common practice. It is generally re-used.
