Seaweed farm at Swansea lagoon could help 'superfood' go global

A seaweed snack could soon be hitting global markets thanks to Swansea's proposed new tidal lagoon.

A £1bn project to harness energy from the Bristol Channel was approved by the UK Government last month.

Now cockle and laverbread producer Selwyn's Penclawdd Seafoods are in talks to build a seaweed farm within the lagoon's sea walls.

If successful, it will enable their seaweed snack, described as a "superfood", to be mass produced and exported across the world.
