Examining the scenarios in Table 9.4 in more detail in Table 9.5 shows the
following;
1. Carbonization of poultry manure
Fertilizer created by reusing phosphorus through the carbonization of poultry
manure is produced commercially. Thus, in this scenario, of the 222.8 kt of phos-
phorus in livestock excreta, 21.2 kt (which is half of the 42.3 kt of the poultry
manure of broilers) was presumed to be subject to carbonization treatment for
reuse as fertilizer.
