Biodiesel in Ireland
Hi Dean, nice to see you are still brewing. I could certainly help you out but it's the distance!

Hi Dave, good to hear from you. Ya I'm still plugging away, when I've got oil that is.
NI is just that bit far away I'm afraid though.

I have WVO "runnin' out'a me ears"
Drop by anytime. I can give you 1000 litres of well settled WVO titrating less than 2.

If I recall correctly Tilly is around about Paradise , Australia. That might be a bit far to go from Ireland to get the 1000 litres of used vegetable oil.

Hi folks is there anybody still making biodiesel? I can finally commit to making it. I'm in Cavan near Virginia. I don't have a supply of wvo yet or a processor and but previously spoke with the local authorities about setting up a tax warehouse to legally use the fuel and it wasn't a flat out no.

It may not be a flatout no but they will probably have you jumping through hoops.
Very little happening here on this site now due to troll. Everybody seems to have moved on.

The latest move in homebrew biodiesel seems to me to be making it without heating. I made a small batch at 26 degrees celcius using roughly 30% methanol plus potassium hydroxide. 26 degrees was room temperature when I did it. In making synthetic fuel the question arises of how much energy does it take to make it compared to how much energy we get out of it upon burning/combusting it. I used new corn oil treated with Magnesol to remove as much ffa's as I could before doing a one pass room temperature base transesterification proceedure. An important thing seems to me to be adequate mixing during the reaction to produce the biodiesel. Removing the free fatty acids should minimize formation of soaps during the reaction.

How are you proposing to dry the oil without heat?

In my post I used new corn oil treated by Magnesol. I heated for the Magnesol treatment. If vegetable oil is taken from a fryer it ought to be dry. I tried to do room temperature transesterification in response to a claim made some time ago that calcium oxide dried methoxide solution would make biodiesel in five minutes at room temperature. In the experiment I did I did not address drying the oil without heating, I used oil that was already dry.

In my experience all WVO requires drying before converting to biodiesel, at least for the best results. It is hydroscopic and contains particulate matter that also holds water.
Some (I believe Tilly) has had success by letting it settle in the hot dry sun and then drawing the dry WVO off the top of the buckets.
That method does not seem to work in my climate.
I have found that I can recover around 5 to 15 liters of water out of seemingly dry and clear batches of 1425 litres of low titrating WVO (using vacuum circulation and heat).
