Hi Adrian and Nigel,
local (to seQLD) commercial BD producders are non existant. So we, like most other around the world are left to our devices. There is loads of solid info available through google. I'd start reading at these websites;
http://journeytoforever.org/biofuel.html http://www.schnews.org.uk/diyguide/h...ebiodiesel.htm.
These are the two I started with. Then I drifted towards the forums once I had the basics, and then I started asking loads of the questions.
I figure I'll need to make somewhere between 200-300lts a month. So I'll be looking at making a 200 ltr batch a fortnight or so. I have all of my quotes and am starting to gather all the equipment. Slowly...
Good luck and welcome to the BD community.
Joe
