Anaerobic digestion of manure provides a first step for subsequent processing to produce stable, concentrated fertilizers that can be sold to generate additional revenue and to facilitate nutrient management. More importantly, this can reduce excess application of nutrients that result from direct manure spreading. Sampat et al. quantify the economic loss associated with excess field-applied phosphorus (i.e., in excess of crop needs) . Using corn (the dominant grain crop in Wisconsin) and crop nutrient requirements from Kissel and Harris , we estimate that the 11.2 tonnes of manure produced by the 245 largest CAFOs would result in 2.45 million kg excess phosphorus applied (i.e., by applying manure to cornfields at a rate meeting its nitrogen requirements). Using the cost analysis of Sampat et al., this equates to 182 million USD/year in avoided social cost due to phosphorus. This cost can potentially be averted under the bioeconomy activated by FERC-2222, as this can help create incentives to deploy nutrient recovery technologies such as solid/liquid separation, ultrafltration, granulation, and struvite production.
