Don't the strawbridges do something like this, down in Cornwall. I am sure it was one of their things a few years ago. |
They did do a course, but I think they've sold up and moved on now.

I wouldn't claim to be an expert, all the vehicles on our fleet are known to be none too fussy, so it doesn't matter too much if we don't get it quite right.
Also I'm struggling for raw materials since I lost my main contract.
But it is not difficult, it just involves nasty chemicals so you have to be careful: I'll wager that safety makes up more than half of any course you go on.
In brief, you do a titration to determine quantities, mix up the nasties and bung them in the oil.
Stir vigorously then leave it to settle, and voila: you have biodiesel, just clean it up* and chuck it in your motor. |

Yes, I agree this would make a good article.
What Im really after is someone to teach an event...Im looking for someone who has taught this before (possibly at a recognised centre or for a sustainable living group),
but your post was a really good insight into how do-able this is at home. |
I'm very active on a specific Biodiesel forum, although I run my vehicle currently on SVO and WVO. I thought I was wel informed on Bio Diesel until I joined a specific forum, then found out the technology and quality of fuel and processing was far beyond the simple processing shown by the Strawbridge's
There are people on there that will show you how to produce it on their processors. I know one in Suffolk and one in Cornwall. There's plenty around though.
There are many sites and products claiming that biodiesel is really easy, buy an off the shelf processor, chuck in some highly toxic and flammable chemicals, switch it on and in 20 minutes you get high grade fuel. Unfortunately it's not quite that simple. You do run the risk of blowing youself up in a cloud of Methanol vapour, or going blind then dead breathing fumes from a non sealed and properly vented system
Firstly you're going to need the raw materials to process anyway, no point building a processor if you have nothing to put in it. The waste oil market's quite competitive with some big players in it, so you will want to ask friends and local businesses what they do with waste oil to gauge whether it's likely you'll have a regular supply.
Graham Laming has a very useful site and information on the GL Eco processor has been used as the basis for many successful plants. It's a good place to start, but you'd be best then joining a proper Bio forum advice. They're mostly a friendly lot, but do search for answers in the forums first as lots of Newbie questions will already have been covered.
Not sure I can post links on here as I'm new, but if you want to have a link to the forum and wiki sites PM me. |
