Annual generation of a manure and wasted food (WF) and b the corresponding phosphorus (P) content contained within these feedstocks. Estimates are based on the annual manure production from concentrated animal feeding operations (CAFOs; indicated with red dots) and wasted food (WF) production at commercial generators (indicated with blue dots) within a transportation range of 20 and 40 km, respectively, from potential anaerobic digester locations. The red star and orange triangle indicate the locations where the largest quantity of WF (Max WF) or WF plus manure (Max WF and Manure Supply) can be sourced, respectively, when the two sources are evaluated separately.
