Can anyone identify projects in the US, preferably the Midwest, that have used ZERI-type integrated technologies that harvest methane, bio-fertilizer, plant biomass and fish from concentrations of animal wastes (hog or cattle)? Can anyone identify people I might contact about this? Can anyone identify people who could discuss the pros and cons (at different scales) of biodigesting and gasifying manure, manure-sawdust mixes, manure-urine mixes, fresh urine, stored manure. Can anyone identify projects in the U.S., preferably the Midwest, that exhaust heat from animal confinement buildings, link greenhouses with animal confinement buildings, use water baths to filter air to remove particulate matter and/or odor from animal confinement building exhaust air, and that use this rinse water in some way? Can anyone identify people I might contact about this? Can anyone identify experts in the range of potential uses of greenhouse (hydroponics, soil-based plant production, ornamentals, vegetables, and so on) linked with animal confinement buildings and/or animal waste streams? Can anyone identify people who can discuss the nutrient value of hog urine; and the potentials and issues associated with use of hog urine as a nitrogen source.

Thanks for your help,
