What you will eventually find is that switchgrass will be used as a thickener to allow the efficient Anaerobic Digestion of swine wastes into Biogas. Swine manure is usually deliverd at about a 6% concentration which is well below the optimum 12% solids content needed for effective digestion in the average AD system. We can handle the 6% solids mix by using some special ultrasonic technology. But, by grinding and adding switchgrass - that is readily digestible - you can greatly increase the digestive efficienty of any swine manure-based system AD system. Our ABPS disgesters will also digest switchgrass by itself quite nicely, producing Biogas support fuel for a coal-fired power boilers, powerhouses, or peaking plants, etc. The Methane from the AD process additionally reduces the overall particluate emmissions in direct proportion to the fueling ratio of Biogas to the coal. Digested switchgrass and manure+switchgrass are excellent and odor-free soil amendment/fertilizer material. A state with economic challenges, but lots of Interstate freeway, could allow planting of switchgrass in the medians (..or even do it themselves..). They could then contract the planting, tending (negligible) and harvesting to nearby farmers, and derive a share of the income by leasing X-miles to each farmer or appropriate civic group at a very reasonable rate. It would certainly beat mowing the existing grassed medians at state expense - at grossly high costs when compared to farmer efficiency. John :-) .
