The report describes plans to harvest up to 34,000 tonnes of kelp per year, an estimated 0.15% of the kelp in Scotland. “The next stage is the full environmental survey, which will be carried out by internationally renowned scientists.” “This scoping report is only the first stage of an extensive consultation process,” said a statement issued by Marine Biopolymers. “Kelp habitats are vital ecosystems that absorb the power of waves along stormy coasts, lock up millions of tonnes of carbon every year and provide shelter for hundreds of species,” said Calum Duncan of the Marine Conservation Society. ![]() Public comment on this report is open until Friday 24 August, and various stakeholders have expressed concern over the proposals.

It comprises use of a comb-like harvesting head (3-4 m wide) that is situated within a curved frame. hyperborea The harvesting technique proposed by MBL is similar to that used in Norway for L.
