I agree that we need to look and keep looking at actual processes to try and find ways to do things better, to look for lost opportunities. Probably wine is best used as an already fermented feedstock for ethanol fuel. Don't know the current price, but relatively decent table wine in Spain used to be cheaper than bottled water. To my knowledge it is difficult to reverse the process that causes vinegar. You're probably stuck with it.
The grape pits are a nice source for oil as it is a byproduct that isn't used for anything else (that I know of). There should be literally tons of grape mashings left over from the production of wine. Rather than have them just go to waste, potentially you have a good source of energy. I don't think it was very cheap to extract the oil for edible use -- based on the price that they sold the grape seed oil in the health food store. However, as someone pointed out, oil extraction could be a lot cheaper if one doesn't care if the end result is an edible oil. There are probably other sources of oil in plants stems and similar that we just haven't ever thought about. I think to that we need to look for things where we benefit twice or more. The prime example of this is the utilization of waste cooking oil. Here is something that has been used already and generally has just been discarded. When we use it a second time in the production of biodiesel, we are gaining a big benefit. In Spain, and Europe in general, (and I fear most of the rest of the world) the big waste product that should be coming down the line will be the rendering of all the animals exposed to BSE and FMD. There will be and have been literally millions upon millions of animals destroyed. This amounts to a huge source of oil that could be used in the production of biodiesel. Regards, Derek W.
