In case anyone is about to claim that Germany only uses rapeseed biodiesel, here are some biodiesel plants in Germany that use WVO and tallow:

So you think they are the only ones?

When exactly did I say that?

BUTLER, KENTUCKY / USA
Feedstock - used cooking oils
and/or animal fats
Today, every modern BDI
multi-feedstock plant offers the most advanced BioDiesel production technology in the world. The latest example is a plant in Kentucky, realised in cooperation with a big US rendering company, using used cooking oils
and tallow with FFA content of up to 20% as feedstock.

Yup, I am well aware of that plant, and that Griffin Industries is using some tallow in their biodiesel. I repeatedly tell people that if they are using biodiesel that has any tallow content in it, they need to be very very cautious about cold weather use, blending in kerosene preferably, and also using antigel additives. There are threads going on over at biodieselnow right now in which I have been telling people that.

If you are using Griffin Industries biodiesel, you are burning some WVO and/or tallow biodiesel. It is not 100% tallow as they use it as a feed stock up to a certain percentage.

Not all Griffin Industries biodiesel has tallow in it, but some does. Again, I tell people to be very cautious using that. The problems in EUrope look like a result of people using 100% tallow biodiesel in the winter, or at least a very high amount of tallow biodiesel. Very bad idea. I only use soy biodiesel right now, with some WVO biodiesel in the summer. I advocate biodiesel from brassica crops (rapeseed, canola, mustard) and algae as options for the future, as well as biodiesel from thermal depolymerization and possibly from gassification and Fischer Tropsch synthesis of waste wood. In what part of my statements here have you concluded that I advocate use of tallow biodiesel?

P.S. Just for your information, I will no longer be posting about the pro's or con's of biodiesel.

Hm, I seem to recall reading that before.... /images/graemlins/wink.gif
Just in case anyone is misunderstanding me - I am not a fan of using tallow biodiesel, especially in the winter. I *might* consider using SOME tallow biodiesel in the summer when the temperature is regularly over 80F. Other than that, I wouldn't. I think waste animal parts should be converted into biodiesel through thermal depolymerization, which gives better cold weather performance than turning it into biodiesel through transesterification (and for tallow biodiesel, anything below about 65F is "cold weather").
There is one, perhaps two plants in the US that use some tallow in making biodiesel. There are many many plants in Europe that use tallow, with some exclusively using tallow and yellow/brown grease, making biodiesel with VERY poor cold flow properties. I feel that that is the dominant factor in the problems Europe has been having.
