Hello Cliff >Sorry for the double post, it was very interesting. >The comments on non-sustainability appears to be someone else's >opinion of why it can't work, without much scientific reasons why >not.
My comments (see below). It doesn't imply that the technology itself "can't work", it rejects the idea that it's a "sustainable" technology for producing fuel. What that immediately transfers to is whether or not concentrated pig confinement operations are sustainable. Such operations are not and cannot be sustainable, the evidence against their sustainability is rather vast. If you want to argue with that, the onus would be on you to provide scientific evidence that such operations are sustainable. In fact there's a large amount of scientific and other evidence to support my comments. You can find some of it here, and from here (there's a great deal more): http://journeytoforever.org/farm.html Small farms http://journeytoforever.org/farm_library.html Small Farms Library - Journey to Forever http://journeytoforever.org/farm_pig.html Pigs for small farms >It still sounds like a good idea and I hope the University >of Illinois continues to pursue it. Even in the article it says >that only 70% is converted, which sounds like to me there is still >some waste to be disposed of. But if some good can come of this, >by all means it should be pursued. It gives more uses for pigs >besides meat and lard. There used to be far more uses for pigs other than meat and lard when pigs (and other livestock) were *farmed* rather than just "produced" without any integration with the land and its requirements. Pigs were and are used for land clearance, for weed control, as a highly efficient refertilising stage in a crop rotation, and more - all jobs which, instead of costing money, labour, time, fuel and off-farm inputs, provide better results and produce good pork, without any of the many problems which make industrial hog production unsustainable. See, for instance (again, there's much more than this one piece available): http://www.ssu.missouri.edu/faculty/jikerd/papers/EconFallacies-Hogs.htm Economic Fallacies of Industrial Hog Production John Ikerd University of Missouri Presented at Sustainable Hog Farming Summit, sponsored by Water Keepers Alliance, White Plains, NY, held at New Bern, NC, January 11, 2001. So the hog farmers have been put in the same position as free-range poultry farmers were put in previously. Just an anachronism, victims of free-market forces? No, just victims of corporate bullying, at the expense of the community at large. Turning the manure lakes into fuel might to an extent help to cure the symptom, or one of them, and in so doing could help to prolong this unsustainable abuse of farming.
