Re: [Biofuel] best oil to make BD

Dear Mr. Tom Irwin: Did you find by your own experience that tallow is a good raw material for producing biodiesel? or there is any bibliography that you can indicate me on the subject?. Your help will be the most appreciated, thanks in advance. Cordially, Mr. F.J.

The main obstacle is that it is primarily a summer only fuel as it solidifies at about 10-14 C. A lot depends on what resources you have and your local climate. If you have a farm with animals that need feed, perhaps canola (non-GM variety) is a good candidate. It has a good oil yield per hectare and a reasonably low iodine value. You can feed the crushed seedcake to your livestock. If you are in a good sized town or city, waste vegetable oil is usually available from restaurants. It's quite variable and more difficult to convert than unused oil but you can usually get it for just your transport costs. If you live in a poorer area then look for wild castor beans. They're have large yields and are generally free for the picking but you can't use the seedcake for animal feed. It composts rather well for a garden or farm soil amendment.  It takes a stronger stomach than mine to deal with the aroma. Castor oil was once used an an emetic to cause vomiting. Other I'm sure have their favorites.   Tom Irwin     From: Mike Weaver [mailto:[EMAIL PROTECTED] To: Biofuel@sustainablelists.org Sent: Tue, 18 Oct 2005 21:28:27 -0300 Subject: Re: [Biofuel] best oil to make BD Free is the best oil to use ;-) Juan B wrote: Hello Everyone, I Would like to know what is the best vegetable oil that can be use to get the most biodiesel ? or it would be better to get animal fat?
