I'm interested in making some biodiesel out of tallow or other similar harder fat, but I currently only have access to cottonseed oil. Is there anyone in the Melbourne area who would be happy to do some kind of swap, litre for litre?

Cheers, Steve.

Hi Steve,
Just wandering why you would want to use tallow when cottonseed makes good fuel?
Cheers Maxwell

Sure, cottonseed makes good fuel!! I just wanted something a bit different to try as well and apparently it has a bit more 'go' in it. Perhaps someone could correct me if I'm wrong.

Cheers, Steve.

Yeah, I reckon from experience animal fat makes biodiesel with more Umph. We once has a batch of chicken fat, which made great fuel, It definitely had more Umph, and had an amazing aroma from the exhaust, Much like KFC. These days Chicken abatoirs throw away most of the chicken skin which contains all the fat. Aparently it takes the skin of 22 chickens to make one litre of Biodiesel.
Go here and read about how the Vietnamese are making BD from Fish fat. Apparently the Vietnamese make 30,000 tonnes per anum of tinned catfood from Mekong delta catfish farms for the US petfood market. But to make it consumable for Cats they have to cook out the Fat in the canning process. The Vietnamese have most of their power derived from diesel generators, and diesel pumps run the fish farm pumps.

Hi All,
Thought it a bit rude to ask why, but glad I did!
Never thought of chicken fat. Would any one know how much oil out of 1kg of fat,what sort of waste is there.
I figure that the lighter oils are going to be harder to get as more people
find out about biodiesel and won't want to have the hassle of tallow.

Cheers,
Maxwell

That's cool Max. We all have to learn these things from somewhere. I only wish my boss were as understanding!! We can't be expected to automatically know everything!!

Tallow makes wonderful fuel too. Just do not expect touse it incold climates or cool ones for that matter. It has to be warm to use it.

Its a fantasy of ours to dumpster dive a lyposuction clinic. Imagine telling people "my car runs on the arse of Fat people."

Lard ,tallow,animal fat makes excellent BD.However they have a high FFA .The industry practise is to either hydrogenate it or mix it with another oil that has a low FFA to arrive at a balance.
I don't see any reason why this principle of mixing cannot be used by us fringe dwellers.
Then we can be unbiased in saying
"Our car runs on fat from all kinda arses".

Dumpster diving a liposuction clinic - sounds a bit like Fight Club (for those who have seen it. For those who have not and make biodiesel, or soap, you must see it, you'll get the parallels)
The first rule of Biodiesel Club is "Do not talk about Biodiesel Club". The second rule of Biodiesel Club is "Do not talk about Biodiesel Club"...

Of course, you could always ask a liposuction clinic, they may just consent (with patient approval) and it could make some great publicity. This guy here in NZ has done just that for his round the world boat trip.
