Marine animal derived

Marine collagen peptide, fish skin

Gadus morhua and farmed Oreochromis niloticusHydrolyzed Collagen

The default Run below is Brittany, France, 4.83 kgCO2e/kg gross, Category C. Published values for this ingredient span 3.10 to 11.40 kgCO2e/kg, which is why a number without its production parameters is not worth forwarding.

  • Allocation decides this number. The default applies economic allocation to the skin, which is the common industry choice, and charges 6.4 kg of raw skin per kg of finished peptide.
  • Limitation. Under mass allocation the figure is materially higher. The Report states both.
  • No biogenic uptake is reported for an animal-derived ingredient.
