I'm not sure it will though, it's a bit unlikely that they'd use such a setup. More likely the company that provides the processor will decide, and they'd quite likely opt for a bigger processor (and lower labour costs?). >What I am trying to do >(besides publicly exposing my ignorance re biodiesel), :-) Never mind, so are they. >is to get some >idea of how it will look on the ground so I can fold that information >into my thoughts about the design of the biogas part of the process, >which (as mentioned) is apparently an afterthought.

[p 22, para 3] :-) So it is sometimes alleged, especially in the world of jatropha it seems. Eg: Production principle: SVO - decentralized small oil expellers Biodiesel - central, big industrial units [Also:] Human toxicity SVO - regularly no or small Biodiesel - toxic And so on - from "Comparison of pure plant oil and bio diesel as fuel" by Prof. E. Schrimpff, FH Weihenstephan, Germany <http://jatropha.org/p-o-engines/svo-bd-characteristics.htm> A rather ignorant professor. Schrimpff hmpff. >And he does not even mention biogas (sniff!). Aw.
