Hi, I have been offered some oil, it is cottonseed. The chap has a restaraunt and hasnt had oil collected in a long time. He has a large drum about 400L that hasnt been emptied.They have been storing the oil in the drums since the big one wasnt emptied, there are about 40 to 50 20L drums.:D. The question is will this oil be ok to use for bio, and how long can oil be stored for before it losese its apeal?
Thanks Brenden

Hi All

I have beem making biodiesel for awhile now using KOH / Methonal for the catylast, and have a few hundred litres of by product “glycerine” black glug.

Question: How can I turn this into fertiliser, is this possible and is it practial.

We are a Hotel in Araluen NSW, we had been asked by someone if they could have our used Frytol, we have been saving it, and now they have changed their mind and have not come to collect it. Is there anyone out there that would like to pick up 8 drums of used Frytol oil. They are 20 litre drums about 3/4full. We are located 1.5hours from Canberra or Batemans Bay or Goulburn, or 1/2hour from Braidwood. Please send “PM” if interested.

Hi bio forumites!

Imagine my delight when unexpectedly I scored 120L of WVO from an unexpected source who found out I was WVOing and extended good will!

Anyway - this arvo I did a random water (so called smear) test.

It failed!! It has a fair few bubbles!

To cut a long story short - I’m not asking how to get rid of water because there are enough threads here on that topic to kill an army. What I’m on about is:

1. Has anyone tested this?
Vegie Cars - Filter Powder

2. I have four weeks to try to get at least 100L ready so I can go on tour with a decent amount of oil to help pay the trip. Any advice to fast track the dewatering? (Or am I going to be working round the clock heating and blowing bubbles through it?)

Many thanks,
Soc.

Hello everyone,

Has anyone attempted to make BD from complete raw animal waste, ie bones, feet, hearts, livers, heads ect.. from cattle and pigs

We have sucessfully made several litres of Tallow BD with no complication
and complete success, using both Pig, and Cattle tallow ONLY.. however the supply we are using to make the BD is fresh from the buthers knife, so we have constructed an industrial scale rendering unit with some misc pices of equipment we managed to gather up and put together.

Anyway here is what we are running into:
We have rendered the materials using the materials own liquid
to render itself down, (i,e it’s own fat/liquid)
drained off the (tallow) fats?… into a holding tank
heated it up 300F to boil of any moistur that may be present in the stuff, did titration correctly sveral times, mixed up the proper amounts of methoxide, lowered the temp to 125F to mix in the methoxide and tried to make a one litre batch before we made a 200L Batch out of all of those materials mixed together anyway,

What we have run into is the famous beigh foam, gel, gloap whatever you want to call it which happpens when you ad too much caustis soda to the solution.

So we tried again, and again with different amounts of Methonal and
casutic soda (lye) and had gotten the same results everytime’
which was a lovely thick gloap of the entire mixture.

So carrying on from that we had tried just tallow (fat) again from the same animal and it worked fine like it always had worked before.

So we began researching again and it seems that all the reasearch
and peronal opinions/experinces that others had lead to the bone Marrow and blood that is present during our rendering phase of the process messing up the chemical reaction that is suppose to happen during the BD process.

So the biggest questions that I need help answering are:

1. If you use water instead of it’s own liquid to boil the materials will that remove the Marrow/Blood mixture from the tallow by settling out at the bottom of the rendering unit after the straight tallow hardens again?

2. Is there anyway that a centerfuige system would remove the marrow/blood out of the tallow? as it seems everywhere you look online, in the production of tallow BD people are using starigt tallow and have never mention anything about marrow or blood in the mixture and what it can do to mess it up.

3. Does anyone have any input, or experince delaing with this same issue and what were your counter measures to ensure a succesfull batch of BD from tallow?

Any feedback would be greatly appreciated!

Cheers,

Darren
