Floating Seaweed Farms

Proposed site for two floating seaweed farms, off Cornwall’s Roseland Peninsula

I​n England, ITV News reports that license applications for two floating seaweed farms off Cornwall’s Roseland Peninsula have been submitted to the Marine Management Organisation for review.

Seaweed farming businesses Biome Algae and The Carbon Sea Garden want to harvest seaweed for food, low-carbon animal feed and fertilizer, and alternative biomaterials to replace single-use plastic and takeaway cartons.

They have submitted identical license applications which state the sustainable farms will involve a range of 3,080 to 9,400 grey surface floats connected by long lines in 22 rows. Each farm site would be 55.3 hectares, with the floating infrastructure occupying a total of 5.5 hectares.

According to the license applications, farming seaweed does not require freshwater, land, feed or fertilizers and it does not produce waste. It can sequester carbon at a rate six times that of trees. 

In a statement to ITV News, Dr. Angela Mead from Biome Algae said, “Sustainable seaweed farming has ecological, economic, and social benefits. Research and evidence demonstrate that seaweed farming contributes positively to the marine environment — increasing local biodiversity, restoring habitats, and protecting species. This includes commercially fished species, increasing local stocks. The seaweed farmed are all native species found within the locality.

“Both Biome and Carbon Seagarden are small, local companies with local connections. Building resilience within the communities in which we operate is important. All at-sea and land-based operations will be local. As such we will be offering local employment opportunities, training, and education.”
