Brown seaweed
Wakame, cultivated and dried
Undaria pinnatifida — Undaria Pinnatifida Extract
The default Run below is Jeju, South Korea, 4.01 kgCO2e/kg gross, Category B. Published values for this ingredient span 1.10 to 5.40 kgCO2e/kg, which is why a number without its production parameters is not worth forwarding.
Species record
- Species
- Undaria pinnatifida
- INCI name
- Undaria Pinnatifida Extract
- Group
- Brown seaweed
- Harvest methods
- Longline cultivation. Vessel harvest, spring
- Conservation status
- Listed among invasive species outside its native range. Cultivated within it.
- Typical uses
- Food, cosmetic actives, fucoxanthin feedstock.
- Declared unit
- One kilogram of dried, milled cultivated wakame at 8% residual moisture.
- Typical gross range
- 1.10 to 5.40 kgCO2e/kg, Category B
- Default sourcing region
- Jeju, South Korea, Route distance, Busan to Rotterdam
- Grid intensity in the processing region usually outweighs the sea freight leg.
- Sea freight over 20,000 km adds less than a diesel truck over 900 km.
