Our upstream processes combine raw material sourcing and separation. Immediately after harvesting, we separate the kelp into two distinct fractions: leaf and stipe.

After harvesting, we stabilise the raw material by separating it into the two specific kelp fractions stipe and leaf. In doing so, we create easy-to-handle starting materials which lay the foundation for our biorefining processes, without using a single drop of formaldehyde to preserve the biomass.
