Hello I am a Biodiesel researcher, looking at taking over a small scale biodiesel production plant. I am looking for the biodiesel bible by Keith Adddison, can anyone help? I tried to purchase on the journey to forever site, however its been inactive since 2013. Any recommendations on helpful biodiesel books for beginners.

I am looking into the dry washing of biodiesel with puroleit, if I am only producing 350 litres per batch with a wet wash will I have a cheaper and more effective process if I moved to a dry wash?

Thank you in advance for any advise,
Kind regards.
