LCI Method PrincipleAttributional
LCI Principles DeviationsAttributional LCI methods used
LCI Method ApproachesAllocation - gross calorific value
LCI Method Deviationsallocation by gross chemical content; 93.7% to eggs, 6.3% to spent hens.
Modelling Constants74% of spent hens to human consumption and animal feed rendering, 26% of spent hens considered as waste due to incineration and composting; 100% of mortalities considered as waste due to incineration and composting; Manure storage: 20.70% covered dry pile, 66.34% uncovered dry pile, 12.96% dry pit.
Modelling Constant DeviationsNA
Data Cutoff/Completeness Principles Infrastructure and farm machinery not considered; Other exclusions are antibiotics, cleaners, and enteric fermentation for poultry. Emissions related to burning of industrial machinery not included.
Deviations from Cutoff/Completeness PrinciplesNA
Data Selection/Combination PrinciplesBased on data from 62 reporting layer facilities representing 31058029 dozen eggs sold.
Deviations from Selection/Combination PrinciplesNA
Data Treatment and Extrapolation PrinciplesStandard excretion rate was assumed for manure production, scaled to reported feed conversion ratios.
Deviations from Treatment and Extrapolation PrinciplesNA
