Guys,

I've been investigating biodiesel for a time, and I did my first batch during the weekend. The final goal is to create high quality diesel from waste oil in 50-100 litres batches. Burger grills have to pay to get rid of their old french fries oil, and with the process I've been testing the waste oil diesel meets the requirements for Swedish DIN standards for diesel.
Pretty cool aight? Happy

Here's a batch waiting for further processing. The bottom layer is glycerol and the rest is pure diesel.

Hmmm quite fancy doing this myself.. being very good friends with the owner of the local chain of chippies getting hold of used oil would not be a problem... so what is the process involved ? one concern I have is... does it make the engine produce chipshop smells ?

cheers

Actually it smells pretty good, depending on the oil. Waste oil smells french fries, rape oil smells burnt bread. Happy

Nasty smell, it feeds the reptile brain and I'm getting hungry of it. Grin

I'm going to be female in a year. Long process, but I promise to bitch around. Wink

But if you were talking about the diesel, this is good reading: http://journeytoforever.org/biodiesel_make.html (don't join the mail list though, they just discuss off topic stuff)
My plan is to build a processor that follows the "fool proof"-process. I'm going to do 50-70 litre batches which will be more than enough for my own driving. Of course it depends if I want to go for 100% bio or mixes with dinofuel, but my car is really low consuming so one batch every month is enough. On the other hand I have friends who want to run biodiesel too, so if I process every second week I will get rid of it anyway.

Be precise, be careful. The chemical catalysators are truly nasty stuff! But besides that it's not more difficult than baking bread. Happy

I've got a friend with a type 4 van and he runs his one 100% vegy oil. In the winter he adds a 1/3 diesel to help with starting but it has been fine all winter. He's done no conversion he just poors in the vegy oil. I was gonna do 60/40 vegy/diesel this winter but I thought I might as well wait until it gets warmer just to aid things.

Love the idea of alternative fuels.

I spoke to a nice lady at HM Customs a few days ago. She informed me that the recent budget was going to allow private users of veg oil to use something like 2100 litres per annum duty free. However there hadn't been a date set to implement this. Anyone got any more "From the horses" mouth information on this potentially great bit of news?

This thred is stolen from the 80 90 site

I'm glad this is what you've been told by HRMC. It means that things are going ahead...

There was a consultation paper out which discussed this in detail. Then the section deep down in the budget...section 7.49

"Following consultation, HMRC will relax
requirements for small biofuels producers to register and submit returns and reduce the
requirement for all but the largest producers from monthly to quarterly returns."

I hope nobody minds me nicking threds from some place els and posting them here

Say what?! I'm not the only one in the world home brewing diesel, of course people discuss it on other places. If the same image resides somewhere else - they have stolen it from me!

I have a new test batch standing in my kitchen, it's bright clear as apple juice and I just need to do the washing process before I use it.

Pugvan, lets clear this: what exactly is "stolen"?

Regards,
